NXP NTAG203

The NTAG203 was the first of the NTAG series of chips from NXP. When the NTAG213 was later released, NXP also released a number of other variants including the NTAG216, NTAG215, NTAG212 and NTAG210. The cut-down featured version of the NTAG210, the NTAG210micro was launched at a later date.

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.
