NFC Tag NFC Stickers White NTAG215 Tag Rewritable Round Coin NFC Cards with Adhesive Back Compatible with Tagmo NFC Enabled Mobile Phones(30Pcs)

Works well with my Switch 2. You can easily write to these using Tagmo and it just works. I'd recommend keeping the tag flat on a table and then placing your phone on top of the tag in order to keep it very still. If you move the tag around while you write to it, the write may fail and you'll have to try again. I've yet to have a tag fail to write, although one took two tries. The smooth side can be written to using a sharpie and the writing does not wipe off easily. You could cut out a circle of paper you've printed something on and stick it to the adhesive side for something more artistic. I haven't tried this yet with Home Assistant, but theoretically you can write data to them to use with automations. The tags scan from a couple of cm away and it even managed to scan a plastic object. The tags aren't very thick, maybe a millimeter or two with the adhesive backing removed. Overall, I think these work great and are a good price for my use.

These nfc tags works just as expected. They're easy to use and are quick in function. They are priced incredibly well and are perfect for those trying to add a little more convenience and automation to their homes.

Cheap and easy to setup as long as you have the app and cache codes to register the “figures”!

These are easy to program and work well and the adhesive sticks very well. My only complaint is how thick they are. They don’t work well for my projects so I ended up going with the very thin flexible ones instead.

They just work, and for the right price. Adhesive has held up for three months so far.

These tags are exceptionally durable and reliable. They work flawlessly, and the data is always easily readable on my smartphone. I even embedded a couple in laser-engraved wooden signs, and the information remains perfectly legible. They're ideal for discreetly displaying payment details or other valuable information.

Fabulous - trying these out in my home - the modern “easy button”! Poor dog doesn’t get two breakfast now - with a nfc programmed to text my partner I’ve already fed her. No yelling up the stairs to empty the dishwasher only to be ignored - text has much better effect - nfc text shortcut set up. One by fridge with shortcut to have irobot vacuum the kitchen - same in the master bathroom/closet. Can’t wait to set up more.

Signal too weak to scan with a switch. It reads on a phone. I've had no issues with other brands. Verified the switch controller is still able to scan tags created from another brand.

Considerando il prezzo vanno bene ma c'è di meglio sicuramente

These work fine with the Home Assistant Companion app on Samsung NFC-equipped phones. I've not tried them with other applications or reader/writers yet but don't expect any problems. They are made of hard plastic less than a millimetre thick and can be written on using, say, a Sharpie. One side has an adhesive coating protected by a peel-off film so they can be stuck to most flat surfaces.

Programs easily, but data is not retained when used outdoors.
