HID 2121BGGMVM Composite iCLASS/Prox 16K/2 Programmable Card with Glossy Finish
When you're deploying a hybrid access control system that needs to support both legacy 125 kHz prox readers and modern 13.56 MHz iCLASS technology during migration or across multiple facilities, you need credentials that work seamlessly across both protocols. The HID 2121BGGMVM composite card delivers dual-technology functionality in a single credential, with 16K bits of iCLASS memory and two application areas for flexible programming across mixed reader environments.
Key Features
- Dual-technology credential supports both iCLASS 13.56 MHz and 125 kHz prox readers in the same card
- 16K bit (16,384 bits) iCLASS memory with two programmable application areas for segmented access control
- Composite construction provides enhanced durability compared to PVC-only cards in high-use environments
- Glossy finish on both front and back surfaces for professional appearance and easy cleaning
- Matching number sequence between iCLASS and prox credentials simplifies credential management and database synchronization
- Standard CR80 credit card dimensions (3.375" x 2.125") compatible with existing badge holders and printers
- Sequential numbering ready for large-scale provisioning and inventory tracking
- Compatible with HID iCLASS readers and standard 125 kHz prox readers without modification
The composite card construction combines PVC with polyester, creating a more rigid credential that resists warping and withstands the mechanical stress of repeated reader presentations better than standard PVC cards. This makes the 2121BGGMVM particularly well-suited for employees who present credentials multiple times daily or in environments where cards experience frequent handling. The dual-glossy finish accepts thermal transfer and dye sublimation printing for photo ID badging while maintaining a professional appearance that resists smudging.
The matching credential number architecture between the iCLASS and prox chips streamlines database management during system migrations. You can program access permissions once and maintain consistent user identification across both technologies, eliminating the credential management headaches that typically accompany dual-technology deployments. The two programmable application areas within the iCLASS segment allow you to separate physical access control from secondary applications like cashless vending, time and attendance, or logical access, all within the same credential.
