CDVI K3 KRYPTO Bluetooth Proximity Card Reader and Keypad

The CDVI K3 KRYPTO Bluetooth proximity card reader and keypad delivers secure, flexible access control for commercial and high-security sites. As a proximity reader/keypad, the K3 combines Bluetooth and NFC mobile credentialing with support for KRYPTO Mobile-PASS and 13.56 MHz MIFARE/DESFire credentials to simplify credential lifecycle and mobile access deployments. Built for integrators, the K3 uses a FULLY secure RS-485 interface and CDVI’s encrypted protocol, ensuring end-to-end protection between the credential, the reader and A22K door controllers. Its compact single-gang surface-mount design and touch-sensitive keypad (4–8 digit codes) make installation quick and provide a familiar user interface for staff and visitors. With an intentional ~2” read range, the reader reduces the risk of unauthorized skimming while maintaining reliable performance in busy entryways. Ideal for access control, security monitoring, and physical security systems in corporate, healthcare, education and government environments.
