IZ2822
description
The IZ2822 RFID circuit with read/write functions is purposed for usage in contactless plastic cards. Application areas: transference supervisory control system, antitheft systems, access control systems in buildings, restricted areas, burglar alarm, registration & identification systems in transportation & technological processes. External coil is connected to create contactless identifier mark. Build-in radio channel receive signal induced in antenna. This signal is used by power supply unit to generate supply voltage & by control unit to separate clocking signal.
