Cypress WRT-4+D2 Key Fob with Smartcard Insert, Supports 4-Bit Encoding and EV2 2K Technology

Designed for enterprise access control and security teams, the Cypress WRT-4+D2 Key Fob delivers a reliable, flexible way to manage doors, turnstiles and monitored entry points. This key fob transmitter pairs long-range 433 MHz RF control (button press range up to 200') with a DESFire EV2 2K 13.56 MHz smartcard insert, so administrators can use a single credential for both remote activation and proximity presentation (up to 3.5"). The four programmable buttons let operators assign multiple functions — from gate and door control to panic or auxiliary commands — improving response times and operational efficiency. Built for real-world security deployments, the compact PC housing includes an LED indicator, accepts a standard CR2032 battery for quick field servicing, and is fully compatible with Farpointe-compatible WRR-22 and WRR-44 long-range receivers. Ideal for access control, surveillance entry integration, and monitoring stations, the WRT-4+D2 supports MIFARE DESFire EV2 credentialing to meet modern RFID security standards. Streamline your credential management and enhance site security — add the Cypress WRT-4+D2 Key Fob to your access control deployment or contact our sales team for volume and integration support.
