These two chips, the NTAG203 and the NTAG213 are from the same NTAG family of chips. They are both manufactured by NXP.
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.
The NTAG213 is part of the NTAG21x series of chips and along with the NTAG210, is the most common. It's a full featured tag with enough memory for almost all standard use cases. Widely available, it's found in a very broad range of tags and products.
Both these chips have a strong ScanStrength and will work very well with mobile phones.
