A pen, some tape and good intentions
Handwritten labels smear in the cold room, fade and vanish. When someone checks the tub, nobody can read it — and what cannot be read gets thrown away.
Kitchen traceability · food safety
Your kitchen’s expiry label, printed in three taps.
MrTag works out the expiry date from the rule you set and prints straight from the phone to your thermal printer. No computer in the kitchen, no box to install — and it keeps printing when the internet drops.
In daily use in a restaurant kitchen in São Paulo since August 2026 — not a prototype.

The notebook on the wall will not survive an inspection
Three things happen in every kitchen that still labels by hand — and all three show up when the inspector walks in.
Arithmetic done from memory
Every product has a different shelf life for every storage method. When the maths happens in someone’s head, the mistake enters stock today and leaves on a plate the day after.
The record that does not exist
The inspector asks when it was prepped and who prepped it. With no history, the answer is somebody’s memory — and memory is not a record.
The cost does not show up as a fine: it shows up in food thrown out because nobody knows if it is still good, and in a cook filling out labels instead of cooking.
How it works, in practice
Three taps from picking up the phone to sticking the label on the tub. No long training, no manual.
01
Who is printing?
The operator identifies themselves by name or PIN before printing. That name goes on the label and into the history — which is exactly what an inspection asks for.
- One account per person, no shared passwords
- Four-digit PIN on the kitchen device
- Every label has an owner
02
Pick the product and the storage method
The catalogue is yours: section, category and the shelf life of each storage method already set up. The expiry date is worked out on the device, by your rule — not by whoever is holding the phone.
- Search by name, internal code or barcode
- Chilled, frozen, ambient, in use, thawing
- A different shelf life per product and per method
03
Check the preview and print
Before any paper is used, the preview shows exactly what will be printed. The label comes out on the thermal printer connected over Bluetooth, local network or USB.
- A preview faithful to what the printer will produce
- Copy count on the same screen
- No internet? It prints anyway and syncs later
What gets printed
Everything a prepared-food label is expected to carry — and everything your brand needs to show.

QR
A QR on every label. Checking takes three seconds.
Whoever points a camera at it — the manager, the customer, the inspector — opens that label’s record: what it is, when it was prepped, how long it is good for, who issued it, batch, health registration and ingredients. Nothing to install, and it works on any phone.
- No app for the person checking
- Shows the live state: in date, due today, expired
- Ingredients and allergens when they are on file
Phone · tablet · computer
One account, every screen in the operation
On the bench, the phone prints a label in three taps. At the prep station, the tablet keeps the day’s plan on screen — and it is the tablet that holds the printer cable when the printer has no network. In the office, the computer opens the dashboard and the reports full screen, with nothing to install.
Phone Android with Bluetooth printing, or any browser — iPhone included.
Tablet The whole print screen in view, with the printer on a USB cable.
Computer Dashboard, reports and catalogue full screen, straight in the browser.
What comes with it
It is not just printing labels. It is the whole prep routine, from the morning mise en place to the monthly report.
Your kitchen’s catalogue
Products by section and category, each with its own shelf life per storage method, ingredients and allergens.
Work plans
The morning mise en place becomes a list. Tick what you are producing and print it all at once.
Expiry dashboard
Expired, due today, due tomorrow and in date — in large numbers, on the manager’s home screen.
Compliance reports
Printed, expired and still open, discarded, consumed, and the share properly closed out over the last 30 days.
Closing a label
Used, discarded or voided in one tap. What left stock stops counting as open.
Team with PINs
Each operator signs in with their own PIN on the kitchen device. The name goes on the label and into the history.
Multi-site
Several kitchens on one account, each with its own producing unit, products and printers.
Your printers
ZPL, ESC/POS and TSPL over Bluetooth, local network or USB. Zebra, Elgin, TSC and most thermal label printers.
Template per product
A product line can carry its own label design and branding without touching the rest of the catalogue.
Batch and health registration
Fields required for animal-origin products, printed only when the product needs them.
Genuinely offline
Catalogue and calculation live on the device. Labels printed with no signal queue up and sync themselves when the connection returns.
Barcode search
Type it or scan with a wedge reader into the search field: the right product opens straight away.
Your brand
Company logo, colour and theme in the app and on the label.
Four languages
Portuguese, English, Turkish and French — each device picks its own.

Runs on the kitchen’s Android device or in the browser on any phone, tablet or computer.

Not a pretty prototype
MrTag runs every day in a restaurant kitchen in São Paulo, printing the service’s labels on a Zebra thermal printer. The system was built from what that kitchen actually needed — not from a feature list imagined in an office.
- A real catalogue with hundreds of products and shelf lives per storage method
- Bluetooth and local-network printing, in daily use
- A dedicated label template for one of the house product lines
- Label history verifiable by QR from day one
What it costs
Remote setup is free — we do it with you over video. On-site only if you want someone in your kitchen. After that, a monthly fee per site, with no charge per label printed.
Remote setup
Free no cost
Over a video call: we load your catalogue with its shelf lives, configure the printer and train the team. This is how most kitchens start.
On-site setup
R$ 499 one-off, optional
If you would rather have someone there on switch-over day: we come to the site, set everything up and stay for the first service.
Monthly
R$ 149 per site / month (BRL)
Unlimited labels, updates, support and accounts for the whole team. Month to month, no lock-in.
Not included: the thermal printer and the label rolls. If you do not have one, we will point you at the right model — we do not sell hardware and take no commission on it.
Book a demoNo lock-in
The fee is month to month. If it does not fit, you stop the following month.
The data is yours
The label history belongs to your operation. If you leave, we hand all of it over as a file.
A demo with your own menu
We do not show a generic example: we build it with your products and shelf lives.
You talk to the people who built it
Support comes from whoever wrote the system, not a call centre.

Questions that always come up
Do I need a different printer?
Usually not. MrTag speaks ZPL, ESC/POS and TSPL, which covers Zebra, Elgin, TSC and most thermal label printers, over Bluetooth, network or USB. Send us your model and we will confirm before you commit to anything.
What if the internet drops mid-service?
Printing carries on. The catalogue and the expiry calculation live on the device; labels printed offline queue up and upload themselves when the connection returns. No label is lost.
Does it work on iPhone?
In the browser, yes: the same screen runs in Safari and can be installed to the home screen. Bluetooth printing needs the Android app — normally the kitchen device rather than the manager’s personal phone.
We already use a spreadsheet or another system. Can we migrate?
Yes. Setup includes bringing your catalogue over with its shelf lives already configured — that is how it went at the restaurant running the system today, with hundreds of products.
How long until the kitchen is printing?
The technical part takes a day. What takes time is reviewing each product’s shelf life with your food-safety lead — and that review is yours, not ours: we do not invent shelf lives.
Does it handle more than one site?
It does. Each site has its own producing unit, printers and team, all under one account. The fee is per site.
Where is my data kept?
On a server dedicated to your operation, in Brazil or in Europe depending on the contract. Each establishment is isolated from the others. No ads, no trackers, nothing shared with third parties.
Is there a contract?
No. The fee is month to month and your label history is yours — if you leave, we hand all of it over as a file.
Start with the demo
Thirty minutes over video, with your own menu on screen. If it does not make sense for your kitchen, we will say so on the call.
