How the NXP DESFire EV2 works
The NXP DESFire EV2 is a 13.56 MHz high-frequency contactless credential read over the ISO/IEC 14443 air interface. The NXP DESFire EV2 is genuine NXP silicon — data structure ISO 14443A; AES-128; MAC'd secure messaging; TransactionMAC; MFKD diversification; Virtual Card + proximity check — 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 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 chip and quantity and we confirm the part before production. Security ID Systems supplies genuine NXP silicon and is independent and not affiliated with NXP.
