HID iCLASS access cards and readers offer high-security, contactless smart card technology for advanced door access control systems. The 2120BGGNMN iCLASS Prox composite card combines iCLASS smart card technology with 125 kHz proximity compatibility, ideal for transitioning from prox to smart access. The 2000PGGMN 26-bit iCLASS BP card is designed for secure authentication using HID's secure communication protocols. Thin cards like 1326 NMSSV and 1386 NGGSN are standard HID proximity cards, while 2000CGGSN and 2002CGGSN are secure iCLASS smart cards with 2k bit memory and application partitions. The 1380 clamshell card offers a durable design for high-use environments, and 1386 LGGMN is a printable smart card version. HID’s 2K2 SIO-enabled smart cards and iCLASS GP (Generic Profile) smart cards provide enhanced security through Secure Identity Object (SIO) data structure for encryption and authentication. These cards are compatible with various HID readers, including the 2104PGGSN, the compact and secure wall switch-sized reader, R10 ProxPoint Plus, the 6005 MaxiProx for long-range proximity access, and the advanced Signo reader series, which supports multiple credential technologies, OSDP protocol, and mobile access—offering scalable, secure, and future-ready door access control solutions.
