NTAG216 vs. NTAG203
These two chips, the NTAG216 and the NTAG203 are from the same NTAG family of chips. They are both 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 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.
