Multi Frequency Contactless Identification Device
Anti-Collision patible with BTG's Supertag Category Protocols
Description
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 identical items. The chip is typically used in “passive” transponder applications, i.e. it does not require a battery power source. Instead, it is powered up by an electromagnetic energy field or beam transmitted by the reader, which is received and rectified to...
