NFC

Blank NFC tags, and what to look for.

An NFC tag closes a reminder with a tap — no camera, no aiming, works in the dark. Any blank tag will do; these are the details that decide whether it works on your object.

You may already own one

Before buying anything: an old transport card, a hotel key card, a ski pass or a work badge is an NFC tag. Enforso can bind a reminder to any of them — it reads what is already on the card and leaves it exactly as it was.

Buy blanks when you want a tag that lives on the object itself: stuck to the pill box, the water bottle, the front door.


What to look for

NTAG213 or NTAG215
The two common chips. Both work; NTAG215 just holds more. Anything sold as "NFC sticker for Android/iPhone" is one of them.
Anti-metal, if it goes on metal
A plain tag stuck to a fridge, a tin or a machine will not read. Look for "anti-metal" or "on-metal" — it has a shielding layer.
A small pack first
10–25 tags is plenty for a household. A bigger pack only makes sense if you plan to hand the spares to friends who want to try it too.
Waterproof for kitchen and bathroom
PVC or epoxy-coated tags survive wiping and steam. Paper-backed ones curl off a bottle within weeks.

A few examples

Programming the tag

By default Enforso does it for you: a blank sticker out of the pack gets written right from the app while you are creating the reminder. If you would rather nothing was written to it, skip that step — the reminder binds either way.

And the tag does not have to be one Enforso programmed. When what you have cannot be rewritten at all — a locked transport card, a hotel key, a work badge — Enforso binds to it exactly as it is.*

* Within reason. The chips listed above are the ones we test against and support; with anything else — exotic, very old or locked-down cards — we cannot promise the phone will read it at all.
