A QR menu solved one problem and left another: the scan. For a hotel or restaurant, the honest version of NFC is this: a tap replaces the scan, not the system behind it. A guest holds a phone near a fixed point and the menu, the order, or the bill opens on their screen. What takes work, and money, is whatever receives that tap.
In short
- A tap opens a link or an identifier. That is what the tag carries; the system on the other end records the rest.
- A tag cannot charge anyone; it only opens the bill. NFC Forum describes a separate mode where the phone acts like a bank card in front of a reader.
- Apple documents reading without an app from the iPhone XS on, with a notification the guest taps first.
- Room access needs an electronic, NFC-compatible lock. The table, the register, and the bar do not.
- Tags cost under ten pesos (MXN) each. The build is the system, not the tag.
What actually happens when a guest taps
The sequence is shorter than a QR scan, but it is not zero steps. Apple documents that on iPhones supporting background tag reading, the system reads NFC data without requiring the user to scan the tag with an app, shows a pop-up notification each time it reads a new tag, and delivers the tag data to the app after the user taps that notification. A locked iPhone has to be unlocked first (Apple, Core NFC).
The same page notes that iPhone XS and later support background tag reading, and that with no installed app tied to that link, the system opens it in Safari. On Android, Google documents that devices are usually looking for NFC tags when the screen is unlocked, unless NFC is turned off in Settings, and that because devices scan tags at very short range, making a user pick an app by hand is likely to push the phone away from the tag and break the connection (Android, NFC basics).
Before you count a point as solved, tap it with the phones your guests actually carry, including one a few years old.
Where NFC earns its place, area by area
NFC does not do the same job in every corner of a property. The restaurant system Walabi buildsalready takes orders table by table, which is the kind of system a tap needs on the other end.
| Area | What the tap does | What to check before you count it in |
|---|---|---|
| Table | Opens the menu with what is available right now and sends the order without a server writing it down | Whether the order lands in the system the kitchen already works from |
| Register | Opens the bill at the table, so nobody has to go back for it | How the guest actually pays once the bill is open, on that screen or on your usual terminal: the tag itself charges nothing |
| Hotel bar or restaurant | Puts the charge straight onto the room account | Whether your property system takes that charge when it happens, not at closing |
| Room | Requests towels or service without calling the front desk, and replaces the key only where the lock is electronic and NFC compatible | Ask the lock manufacturer whether it already issues a phone key, and through which system |
What the tap records is what owners end up caring about: what was ordered, how long service took, which table turns over fastest, which dishes go out together. None of it lives on the tag, which carries an identifier or a link. The system receiving the tap stores it and puts it on the operations dashboard.
If orders also arrive through other channels, how to take WhatsApp orders without losing anycovers the same problem from a different entry point: getting the full order to the kitchen.
What it takes to set up
For the table, the register, and the bar, nothing gets renovated: the points are small, programmable tags placed on what is already there, they cost under ten pesos (MXN) each, and they last for years. Phone-as-key is the exception, since it needs an electronic, NFC-compatible lock.
Range is short by design. NFC Forum puts the certified compliant range at 5 millimeters, with a typical range of up to 2 centimeters (NFC Forum). So the tag goes where a hand already lands, the table edge or the door frame at handle height, not a wall across the room.
The money goes into the system that turns a tap into an order, a ticket, a notification, or a record. That part gets built to spec. Walabi builds it: its Nova ID CRMalready includes NFC alongside WhatsApp, kanban, and AI bots, so the tap can stay inside the same system running the rest of the business.
What to ask before you sign
Hiring a provider in another country adds questions the technology does not answer.
- Who owns the code once the system is finished, and does the contract say so in writing? Settle it before the first tag goes up, not after.
- What happens to the tags already stuck to your tables if the system changes? Ask who writes the same link or identifier onto new tags, and how long that takes.
- Who picks up the phone when a point stops working, in which language and from which time zone?
If you want to see what this would look like in your property, Walabi's 30-minute call is free, held in Spanish with a person, not a bot: you leave with a map of what an existing product already solves, what would have to be built, and what is not worth touching yet.
Frequently asked questions
Does a guest have to install anything?
Not on an iPhone from the XS on: Apple documents reading without an app, with a pop-up notification the guest taps first. On Android, Google documents that devices are usually looking for tags when the screen is unlocked, unless NFC is switched off. Test with the phones your guests carry.
What happens when a tag stops working?
You replace it. Tags cost under ten pesos (MXN) each and last for years, so keeping spares is cheap. The part worth settling with your provider is who writes the same link or identifier onto the new tag, and how fast.
Will the discovery call be in English?
Walabi's call runs in Spanish, with a person on the line rather than a bot. If nobody on your side speaks Spanish, agree beforehand how you want to handle it instead of finding out once the call starts.
What if the property is not in Mexico?
That is a question for the provider, not for the technology. Ask who installs the points, who supports them and from which time zone, and whether a price quoted in Mexican pesos covers getting the tags to you.
