Why not all products are found using a barcode scanner - and where our data comes from

Matthias Schmid

In this article, we give you a look behind the scenes at how we process barcodes and where our product data comes from.
How does a barcode work?
A barcode, also known as a stripe code, is a machine-readable identification number. It makes products identifiable for commercial use and retail - ideally unique on a global scale.
The first barcode (Universal Product Code, abbreviated UPC) was introduced in 1973 in the USA. The commonly used UPC-A in the USA consists of 12 digits. It quickly becomes apparent that, aside from the country and the manufacturing company, not much information is contained within those 12 digits.
An EAN13 barcode - the machine-readable part on top, below the encoded 13-digit identification number. No more information is contained directly in the barcode. By VaGla - own work created in Inkscape based on the graphics by Grzexs, CC BY-SA 3.0
In Europe, three years later in 1976, the European Article Number (abbreviated EAN) was introduced. It is 13 digits long and compatible with the UPC system.
Identification scheme since 2015
Since 2015, the identification numbers used worldwide in commerce have been renamed to Global Trade Item Number (GTIN). It is 8, 12, 13, or 14 digits long and always contains a check digit to detect errors during machine reading.
How does one access the product data?
GS1 Germany GmbH based in Cologne is the only official provider of EAN8/EAN13 codes in Germany. Anyone who wants to sell a product with a barcode must purchase a unique barcode from there.
Up to 30 barcodes can be retrieved for free per day from there - however, without all the relevant sizes that are of interest for the storage of food. For example, the product name, the package size, and the nutritional values are missing.
As a test, I used the official barcode search of GS1 Germany called Gepir to look up a randomly selected item: A pack of Haribo from an Edeka in Munich. The barcode 8426617106201 immediately reveals the country that issued the barcode: The two digits on the left stand for Spain (84).
The search in Gepir yields the following result: Company name "HARIBO ESPAÑA S.A.U." as well as an address.
Unfortunately, we can't do much with this yet. Commercial use of the service is costly and does not provide us with the data we are interested in. At a minimum, these would be: name, quantity, nutritional values of the food, and information on any allergens it may contain.
The first pantry app with product data: Crowdsourcing
When we launched the first pantry app in the App Store in 2013, there wasn't even a barcode scanner - and accordingly, no product data was stored.
Each user had to enter their items manually, which was quite laborious. In December 2015, the time had finally come: We created a product database for the pantry, with which users still had to enter food items, but these were then shared among all users! This way, at least common items were usually already in the database, and the recording of stock or shopping became much faster.
However, over time, weaknesses of the approach have become apparent:
Thus, there was only one field per article for the product name - even though the app was also used internationally. People then filled in the name sometimes in Swedish, sometimes in English, sometimes in German.
Although the app had storage locations, it seems that these were not sufficient for organizing items for some users. Thus, cryptic category names like "30 Juice", "31 UHT Milk" quickly emerged, which were only understandable to the respective user.
Some users have meticulously transferred all nutritional values - others have completely skipped this part. The level of detail of the products varied accordingly. Excerpt from the product database of the Pantry App, where product names have been entered by different users in various languages.
The current Pantry WebApp
Before we released our current WebApp for public beta in 2019, we spent a long time searching for the right model regarding the product database. We considered how we could improve the quality of the existing data.
Ultimately, we have actively decided to stop using our own product database and instead switch to the open model of OpenFoodFacts.org. Here too, product data is maintained by volunteer users and stored in a publicly accessible database. However, the project has several advantages, as we will see in the following section.
Keep track of supplies, groceries and durable products before small price increases turn into unnecessary extra costs.
Discover SmantryProducts can be accessed directly from OpenFoodFacts and used for one's own purposes. The product data is licensed under the Open Database License - this ensures the data can be used for any purpose - as long as newly added product data is contributed back - thus the crowd-sourcing effect is ensured through the license.
A few facts about OpenFoodFacts
- OpenFoodFacts was founded in France in May 2012
- Meanwhile, there are 1,875,095 product data from all over the world listed with barcodes
Compared to our first database, OpenFoodFacts has a very extensive data schema. For instance, name fields are provided for any language.
Additionally, OpenFoodFacts allows for the uploading of photos of the product, the list of ingredients, and the nutritional value table. This enables automated machine quality control of the entered nutritional information, significantly improving the quality of the data.
Everything that can be found on OpenFoodFacts about the bag of Haribo from the example above can be found here.
Pantry App and OpenFoodFacts
Since October 7, 2019, we have been retrieving product data from OpenFoodFacts and, of course, also contributing back for the benefit of all users.
Since then, our users have created 10,184 articles from scratch and edited 20,441 articles, mostly to add missing attributes.
With this, our users have created 0.5% of all articles in the global database - that's an impressive sum, from which users in Germany benefit especially! A heartfelt thank you at this point for the careful entry of data, which will be very conveniently available to all future users.
Although it may happen that individual products are not found when scanning, we believe in the approach: A product database maintained by users is independent of the interests of food manufacturers, can be expanded as needed, and is unrestrictedly usable for all future purposes.
So if you come across an article that is not found, and you have to enter it yourself - think of the many users who will also scan the article, they will thank you for your product entry! 😊

Smantry? Yes, it’s still us. Why we changed our name from Speisekammer.App to Smantry
Maybe you recently searched for “Speisekammer App” and suddenly saw a different name. Maybe that confused you, or you thought the app no longer exists. Maybe you even switched to another app because you couldn’t find us again.
We’re sorry about that. And that’s exactly why we’re writing this article today.
We’re still here. We are Smantry. And we’d be happy to explain to you what happened, why we took this step, and why this really only means good news for you as a user.
What was Speisekammer.App anyway?
Speisekammer.App was the name we started with. The idea behind it was as simple as it was important: an app that helps you keep track of your pantry, reduce food waste, and shop more smartly.
Every day, food ends up in the trash just because people forgot there was still something in the fridge. Because they bought the same thing twice. Because the best-before date was overlooked. Speisekammer.App set out to change exactly that, with a digital pantry system that simply works.
And it worked. Thousands of people have used the app, organized their fridges better, and thrown away noticeably less. That makes us proud.
But at some point we realized: the name is holding us back.
Why the name Speisekammer.App has reached its limits
A good product name grows along with the product. And that was exactly where the problem lay.
"Speisekammer" is a wonderful German word. Everyone knows it, everyone understands it immediately. But it is also a very specific word. It describes a place, a single room in the house where supplies are stored.
What we’ve built has long since grown beyond this one room. We don’t just help you manage your pantry. Together with you, we think about how your household as a whole can handle food more consciously: from the shopping list to using up leftovers, all the way to the question of what you can even cook this week based on what you already have at home.
➜ Simple tricks for using the Smantry app
On top of that, the name Speisekammer.App made it hard for us to think internationally. An app that only works in German because its name stops making sense once translated is a structural problem. Smantry, on the other hand, works in any language, sounds modern, and is easy to remember.
What is behind the name Smantry?
Smantry is a combination of smart and pantry. In other words: the clever, forward-thinking version of your food cupboard.
Smart here doesn’t just mean intelligent in the technical sense. It stands for a new way of thinking about everyday life: wasting less, consuming more consciously, planning better, without making life more complicated. Quite the opposite.
➜ Smantry: Not perfect – but made with a lot of heart
Pantry is the English word for larder and has experienced a kind of comeback in recent years. More and more people are talking about pantry organization, meal prepping, and zero-waste cooking. Smantry builds on exactly this and combines the trend with a practical, everyday-friendly tool.
The name may not feel as familiar yet as “Speisekammer”. We understand that. New names take time. But we believe that Smantry is the right name for what this app is today and what it will become tomorrow.
What has changed for you as a user? Spoiler: Very little
This is the most important section of this article, so we’ll read it through slowly together.
Your account still exists. Exactly as you left it.
Your data is still there. No losses, no gaps, no restart.
Your lists, your products, your settings: everything is preserved.
The app will continue to work on your device. You don’t need to sign in again, set anything up again, or re-enter anything.
What you see is a new logo, a new name, and a freshly designed interface that’s clearer and more intuitive than before. But the heart of the app—your data and the system behind it—has stayed the same. We’ve only renovated the house, not torn it down.
➜ All the new features in the Smantry app at a glance
Why we are writing this article now
Because trust is the most important thing we have.
In the past weeks and months, we’ve noticed that many users who used to actively work with Speisekammer.App could no longer find us. They searched for the old name and were left confused. Some left because they thought the app had been discontinued.
That wasn’t a planned transition, that was a gap. And we’re going to close that gap now.
If we had lost you: welcome back.
If you’re just finding us for the first time: we’re glad you’re here.
And if you’ve stuck with us through all the changes: thank you. You’ve driven us forward.
Smantry and the issue of food waste, a mission that has not changed
No matter what we’re called or what we’re about, that stays the same.
In Germany, millions of tons of food end up in the trash every year. Most of this doesn’t happen in restaurants or supermarkets, but at home, in private households, at your place and ours. Yogurt that has passed its expiration date. Vegetables that were forgotten. The leftovers from Monday that didn’t make it to Wednesday.
➜ Making a lot out of a little: How to whip up simple recipes from your leftovers 🥕🥖✨
Smantry is our answer to this. No wagging finger, no logic of renunciation. Instead, a tool that makes your everyday life easier and at the same time helps ensure that less is thrown away. Good for your wallet. Good for the environment. Good for your conscience.
That was the mission of Speisekammer.App. That is the mission of Smantry. No difference.
What comes next
The name change wasn’t an endpoint; it was a fresh start. In the coming months, we will continue to develop Smantry, release new features, and further grow the community around mindful shopping and smart pantry management.
You can be part of it.

Hope, the whale, and what his fate has to do with our shopping basket
From awareness to responsibility: Why each of us should think of Timmy the next time we buy fish.
Since the beginning of March 2026, a humpback whale has been keeping Germany on edge. First spotted in the port of Wismar, “Timmy,” also affectionately called “Hope,” had become entangled in a net and was rescued. Since then, volunteers, veterinarians, politicians, and the entire nation have been emotionally fighting for him. Human chains, rescue boats, sandbags, drones. Everything is being tried to save this one animal.
That’s beautiful. And it’s a good thing.
But it also confronts us with an uncomfortable question: Why are we so deeply moved by a single whale, while every day we buy products that systematically kill whales and dolphins?
What connects Timmy with our everyday life
Timmy’s story is not just a natural spectacle. It is also a mirror. According to Wikipedia, his appearance on German coasts is a sign of the partial recovery of humpback whale populations – the result of decades of international protection measures and the moratorium on commercial whaling. Protection has worked.
At the same time, Timmy may be dying from exactly what happens every day: fishing nets.
His first appearance: he had become entangled in a net.
Bycatch: The Invisible Catastrophe
Bycatch is the leading cause of death for marine mammals worldwide. What few people realize: with every fish stick, every can of tuna, every shrimp cocktail, this silent mass dying can be co-financed.
What exactly is bycatch? When fishing with large nets (trawl nets, gillnets or purse seines), it’s not only the target fish that end up in the net. Whales, dolphins, sea turtles, sharks and seabirds are also caught. Many die in agony because they can no longer surface or are injured by the pressure of the net.
Particularly dramatic: the death of a single whale can destabilize an entire family group. Whales live in close social units. If the experienced matriarch, who knows the best feeding grounds, dies, the entire group suffers.
The MSC label: No free pass for whales
Many consumers trust the blue MSC label (Marine Stewardship Council) as a guarantee of sustainable fishing. The problem: even MSC-certified products do not guarantee adequate whale protection.
According to a study by NABU and BirdLife International, only 13% of the MSC-certified fisheries examined received a good rating on the issue of bycatch. For the overwhelming majority, the unwanted bycatch rates of whales, dolphins and other threatened species did not even decrease after certification.
The Whale and Dolphin Conservation organisation (WDC) is also clear: MSC certifications do not guarantee that whales and dolphins did not suffer or die during the catch.
Which fish products are particularly problematic?
These products and fishing methods are particularly under criticism:
🚫 Avoid or question
- Tuna from purse seine nets (often canned). High dolphin bycatch; even MSC-certified fisheries in the Mexican Pacific have been criticized
- Prawns and shrimpEspecially from trawl fisheries using bottom trawls, which also destroy the seabed; in addition: North Atlantic prawn and lobster fisheries demonstrably contribute to the decline of the North Atlantic right whale
- Fish sticks, breaded fish and convenience products.Here, the origin and fishing method are often not declared.
- Krill products (dietary supplements, omega-3 from krill). Krill is the main food source for whales; fishing it literally deprives them of their means of survival
- Gillnet fishing in the North and Baltic Seas. According to WDC, very likely associated with negative impacts on harbour porpoise populations
What can we do? The good news
Consumption plays a part in the decision. And this is where smantry becomes relevant: anyone who shops consciously, wastes less, and deliberately chooses alternatives is already doing a lot.
📱 How the Smantry app helps
When you use Smantry to plan your food and avoid leftovers, you automatically reduce your footprint – including on the oceans. Anyone who plans more consciously shops more purposefully, chooses plant-based proteins more often, and takes a second look at the label when buying fish.
Tip: Use Smantry to replace fish meals more often with sustainable alternatives, e.g. legumes, mushrooms or tofu as the main protein source, and save fish for moments when you really know what’s in it.
The conclusion: Timmy as a turning point?
Millions of people have been rooting for Timmy in recent weeks. This shows how deep our connection with these fascinating animals is. Now it’s time to turn this feeling into action.
Because while Timmy’s rescue is in the spotlight, whales and dolphins are silently dying in nets every day. Without a name, without a hashtag, without a live blog.
Let’s make sure that the empathy we feel for Timmy doesn’t end with his fate, but begins with our next purchase.

Organize your cosmetics: How to stay on top of everything (and avoid unnecessary waste)
Do you know that?
You’re looking for your favorite cream and instead you find three half-used ones.
Last summer’s lipstick is buried somewhere at the very bottom.
And with the mascara you’re wondering: Can I still use this… or is it better not to?
Cosmetics can quickly become confusing. And just like with food, something happens here that many people underestimate:Products are bought twice, forgotten, and ultimately thrown away.
But it can be done differently.
Why organizing your cosmetics is so important
Cosmetics, just like food, have a limited shelf life.
The problem: it’s often less visible.
Many products bear the so-called PAO symbol (Period After Opening), for example:
- 6M → 6 months shelf life after opening
- 12M → shelf life of 12 months
- 24M → Shelf life 24 months
👉 But: Who actually remembers exactly when something was opened?
The result:
- Uncertainty in use
- Skin irritation caused by expired products
- unnecessary new purchase
- more trash
The solution: Organize your cosmetics like your pantry
With the Smantry app you can not only manage your groceries –
but also organize your cosmetics smartly.
And this is where it really gets exciting.
How to use the app for your beauty products
1. Record all products
Simply add your cosmetic products in the app:
- Face creams
- Make-up
- Hair products
- Sunscreen
- Perfume
💡 Tip: Create categories like “Skincare,” “Makeup,” or “Haircare” so you can find everything again more quickly.
2. Record opening date
This is the game changer.
As soon as you open a product:
👉 enter the opening date in the app
This way you can always keep track of:
- how long you have been using it
- whether it is still safe
💡 Especially important for:
- Mascara (very short shelf life!)
- liquid products
- Natural cosmetics
3. Keep an eye on shelf life
Even though cosmetics don’t have a classic “best before” date:
👉 You can set your own reminders
👉 or sort by usage time
This is how you immediately recognize:
- which should be used up soon
- which has been open for a long time
4. Avoid duplicate purchases
How many times have you bought something and only realized at home:
"But I’ve already done that…"
With your digital overview, that won’t happen anymore.
👉 Take a quick look in the app before buying
👉 see what you really need
This saves:
- Money
- place
- Resources
Sustainability starts in the bathroom
Cosmetics is an often underestimated area when it comes to sustainability.
Many products:
- contain microplastics
- come in elaborate packaging
- are disposed of when half full
With better organization, you can:
✔ Use up products completely
✔ Consume more consciously
✔ Reduce your waste
Bonus: Less chaos in your head
Keeping things tidy in the bathroom also means:
- less stress in the morning
- clearer routines
- more conscious decisions
You just know what you’ve got.
And that changes more than you’d think.
Conclusion: Small habit, big impact
Organizing cosmetics might sound trivial at first.
But it isn’t.
Because this is exactly where the following are hiding:
- unnecessary expenses
- unconscious consumption
- avoidable waste
👉 With the Smantry app, you create transparency
👉 and take another step towards a more mindful everyday life
Challenge for you:
Open your bathroom today, pick 5 products and enter them into the app.
Include the opening date.
You’ll be surprised how quickly the way you look at your own things changes.
