With the new HITAG S family, NXP has extended the HITAG platform with the next generation of IC’s that are substantially smaller in size, lower in cost, quicker speed, better distance but still being operated with the same reader infrastructure and transponder manufacturing equipment. The protocol and command structure for HITAG S is based on HITAG 1, including anti-collision algorithm.
There are two memory sizes available (operating using the same protocol) - HITAG S256 and HITAG S2046.
