Ultralight EV1 (48 Byte) vs. Ultralight EV1 (48 Byte)

These two chips, the Ultralight EV1 (48 Byte) and the Ultralight EV1 (48 Byte) are from the same MIFARE family of chips. They are both manufactured by NXP.

The NXP MIFARE Ultralight® EV1 is a updated version of the very popular Ultralight chip from NXP. The original Ultralight chip dates back to 2001 and the product has been used for ticketing the world over. It’s a very simple, reliable and cost effective product. Unfortunately, there’s probably almost as many non-genuine MIFARE Ultralight chips as genuine ones. The EV1 update added an originality check feature to help counteract this.

There are two variants of the Ultralight EV1 with two memory capacities. The smaller chip has 48 bytes of usable memory (similar to the NTAG210 and NTAG210micro) and the larger has 128 bytes (similar to the NTAG212).

Both these chips have a strong ScanStrength and will work very well with mobile phones.
