Xuhal 100 Pcs Black NFC Cards Blank 504 Bytes Memory Color Tags Digital Programmable Business Card Chip,

Very good unbrickable cards, or at least, That's what I received. Not quite the read distance of some others, but perfectly ok. With a proxmark and the *correct commands*, you can make mistakes with, say, amiibo cards and go back, unlock and fix it. Of course, UID, and OTP can be changed as much as you like. Non Gen1b cards cannot do this and once locked, have to go to landfill. Unfortunately, I've found that most sellers are ending up getting the bad(normal) cards even if they were stocking the gen1b's originally, so I can't guarantee what you'll get in the future!

Excelente, reconoce rápido y sobre todo no fallan. Podría tener un valor agregado de enviarlos con logo personalizado. Opciones para más colores

Excellent item, I used these for business networking for my technicians

The sleek black gives a premium look

The description says that these can be customized and decorated and has a picture of a heat press but these cards cannot withstand the high temperature and melt and deform quickly. Even at low temps like 280 for 10 seconds. The NFC works fine for website and contact info and can be easily be written using free apps. But if you're looking for cards that you can press vinyl or dtf then you'll have to keep looking. :(
