50 PCS NFC Tags Sticker with NTAG213 Chip Blank NFC Stickers Adhesive Labels RFID Tags Rewritable 144 Bytes Memory Compatible with All NFC-Enabled Smartphones and Devices

I've four so far for various automations in the iOS Shortcuts app on my iPhone and they've worked well. But note, it seems like sticking them to a conductive surface permanently disables them. I tried sticking one to a piece of silver trim in my car (which I thought was plastic) and the tag stopped working even after I peeled it off and it visually seemed fine. I thought it was a dud so I tried another tag and the exact same thing happened (and I verified it was working right before sticking). But as long as you avoid metallic-looking surfaces, they seem to work well. I'm only using these to trigger automations on my phone, so I have not attempted to read or write any data with them. They're quite compact and easy to stick onto anything. They unlock a lot of possibilities: any routine task you do, app you open, or setting you change that is associated with a location or object can now be automated.

El producto funciona muy bien y se programa fácilmente con nfc tools. Lo he probado y usado tanto en iPhone como en Android y funciona de maravilla.

Works great! Embedded into a plastic ring that is 3mm thick, picked up by several phones. Worked best with apple devices, android surprisingly was hit or miss. Read through phones with cases as well. Great range. Id say upto 10mm applications should be fine.

They work, they’re cheap, a little bigger than some micro nfc tags. Can’t complain. If I had to be a whiner, I wish for their size they would be detected a little easier.

Great product. 4 stars because their photo of the product is extremely misleading.
