Keri Systems DK1-3 Key Tag Smart Card, 13.56 MHz

Optimize site access and simplify credential management with the Keri Systems DK1-3 Key Tag Smart Card. This MIFARE-compliant key fob delivers a practical, battery-free solution for access control, security monitoring, and on-site surveillance programs. With a 13.56 MHz operating frequency and 1 kB custom-format memory, the DK1-3 can be ordered pre-programmed to common Wiegand formats and supports Keri’s MAXSecure and ValidID features for enhanced fraud detection and data integrity.

Designed for busy commercial, education, and healthcare environments, the DK1-3 combines a compact profile with a reinforced brass eyelet to withstand daily wear on keyrings while ensuring consistent read performance up to 0.75 inches (19 mm). Because it is a passive tag, organizations reduce lifecycle costs associated with batteries and maintenance. Integration is straightforward: the DK1-3 interoperates with Delta readers and many third-party access control systems, enabling centralized monitoring and streamlined credential issuance.

Choose the Keri Systems DK1-3 when you need dependable, secure credentials for employee badges, visitor management, or multi-site access control. Contact us to order pre-programmed formats or to request volume pricing.
