Are there compact solutions with NFC tag?

Question

Smart cards

There was an idea to independently make thin bracelets with nfc tags for constant wear, most likely the material will be leather. It’s very reluctant to make bracelets wide (maximum width 2cm), but I didn’t find compact marks, they usually sell stickers with a diameter of 20mm or more.
At first, there was an idea to implement it not on NFC, I looked at long and narrow RFID tags, but they are of the iso 18000-6C standard with a huge range and the ability to read a large number of tags at once, a fly-gun is shorter.
There are a number of questions:
1) Is it possible to bend the nfc sticker several times several times (of course, without damaging the tracks) and will this affect the ability to read data?
2) Are there really compact ISO14443 tags?
There are a lot of large stickers on the market, or small ones that seem brittle for a pcb bracelet.
