Ultralight EV1 (48 Byte) vs. NTAG203
These two chips, the Ultralight EV1 (48 Byte) and the NTAG203 are from different NFC chip families. The Ultralight EV1 (48 Byte), manufactured by NXP belonging to the MIFARE family, and the NTAG203, also 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).
The NTAG203 was the first of the NTAG series of chips from NXP released in 2011. The previous generation to the current NTAG series of chips.
The NTAG203 is no longer in production and we very, very strongly recommend that you do not purchase any tags using this chip. They are either very old or non-genuine NXP chips.
Both these chips have a strong ScanStrength and will work very well with mobile phones.
