NTAG216 vs. Ultralight EV1 (48 Byte)

These two chips, the NTAG216 and the Ultralight EV1 (48 Byte) are from different NFC chip families. The NTAG216, manufactured by NXP belonging to the NTAG family, and the Ultralight EV1 (48 Byte), also manufactured by NXP.

The NTAG216 has the largest memory capacity of the NTAG21x range. It's typically used in business cards and similar vCard storage applications. With a better availability than the smaller memory NTAG215 chip, it's essentially the only option if you need more memory than the NTAG213. It's not a cheap chip and prices for NTAG216 tags carry a heavy premium. Seritag strongly recommend that NFC tags shouldn't be used to store data but contain only the link to data. In which case, using a large memory chip such as the NTAG216 isn't always a good idea in the first place. However, if your application absolutely requires it, this chip is an option.

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.
