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. :(

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

The sleek black gives a premium look

Its good working.

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!Proxmark info shows the following!hf mfu info[=] --- Tag Information --------------------------[+] TYPE: NTAG 215 504bytes (NT2H1511G0DU) ( Gen 1b )[+] UID: 04 C1 7B CF 2D 02 89[+] UID[0]: 04, NXP Semiconductors Germany[+] BCC0: 36 ( ok )[+] BCC1: 69 ( ok )[+] Internal: 48 ( default )[+] Lock: 00 00 - 0000000000000000[+] OTP: E1 10 3E 00 - 11100001000100000011111000000000[=] --- NDEF Message[+] Capability Container: E1103E00[+] E1: NDEF Magic Number[+] 10: version 0.1 supported by tag[+] : Read access granted without any security / Write access granted without any security[+] 3E: Physical Memory Size: 496 bytes[+] 3E: NDEF Memory Size: 496 bytes[+] 00: Additional feature information[+] 00000000[+] 000 .... - RFU[+] ...0 ... - Don't support special frame[+] ....0 .. - Don't support lock block[+] .....00 - RFU[+] .......0 - IC don't support multiple block reads[=] --- Tag Counter[=] [02]: 00 00 00[=] TAG IC Signature: 00000000000000000000000000000000[=] : 00000000000000000000000000000000[+] Signature verification: failed[=] --- Tag Silicon Information[=] Wafer Counter: 16795065 ( 0x10045B9 )[=] Wafer Coordinates: x 449, y 635 (0x1C1, 0x27B)[=] Test Site: 7[=] --- Tag Version[=] Raw bytes: 0004040201001103[=] Vendor ID: 04, NXP Semiconductors Germany[=] Product type: NTAG[=] Product subtype: 02, 50pF[=] Major version: 01[=] Minor version: 00[=] Size: 11, (512 <-> 256 bytes)[=] Protocol type: 03, ISO14443-3 Compliant[=] --- Tag Configuration[=] cfg0 [131/0x83]: 040000FF[=] - strong modulation mode enabled[=] - pages don't need authentication[=] cfg1 [132/0x84]: 00050000[=] - Unlimited password attempts[=] - NFC counter disabled[=] - NFC counter not protected[=] - user configuration writeable[=] - write access is protected with password[=] - 05, Virtual Card Type Identifier is default[=] PWD [133/0x85]: 00000000 ( cannot be read )[=] PACK [134/0x86]: 0000 ( cannot be read )[=] RFU [134/0x86]: 0000 ( cannot be read )[+] --- Known EV1/NTAG passwords[+] Password...
