EM4022 compatible equivalent, multi frequency contactless identification device anti-collision compatible.
Implements all BTG anti-collision protocols: Fast SWITCH-OFF, SLOW-DOWN, and FREE-RUNNING Can be used to implement low frequency inductive coupled transponders, high freq.
It is even possible to identify transponders with identical codes, thereby making it possible to count identical items..
The EM4022 (previously named P4022) chip implements patented anti-collision protocols for both high frequency and low frequency applications. It is even possible to identify transponders with identical codes, thereby making it possible to count ident.
