How the MIFARE Ultralight EV1 48-byte works
The MIFARE Ultralight EV1 48-byte is a 13.56 MHz high-frequency contactless credential read over the ISO/IEC 14443 air interface. The MIFARE Ultralight EV1 48-byte is genuine NXP; disposable hotel silicon — data structure ISO 14443A; 7-byte UID; 48 bytes; 32-bit password + counters + originality signature; no sector crypto — the same chip platform the major lock, transit, hotel and payment systems specify.
We stock it as an encodable blank, supplied unprogrammed or pre-encoded to your specification, so your access-control system, card bureau or application writes it with your own data and keys — exactly as you would chips ordered through the NXP; disposable hotel distribution channel, at a fraction of the price. There is nothing aftermarket about the chip itself; what we add is sourcing, encoding and bulk availability.
Whether you need a handful of spares or a bulk run for a facility, transit programme or NFC project, tell us the exact NXP; disposable hotel chip and quantity and we confirm the part before production. Security ID Systems supplies genuine NXP; disposable hotel silicon and is independent and not affiliated with NXP; disposable hotel.
