Keri Systems PDT-1 Pyramid Series Proximity Disc Tag, Wiegand, 3.5" (88mm), PVC, Glossy White

Reduce credential clutter and speed secure access with the Keri Systems PDT-1 Pyramid Series proximity disc tag. This compact, glossy white PVC tag adheres to an existing card, phone or wallet so employees no longer need multiple credentials when sites expand. Built on proven 125 kHz RFID technology with Wiegand output, the PDT-1 integrates smoothly into access control and security monitoring systems used in corporate, education, healthcare and government environments.

The PDT-1 offers a practical operating range of up to 3.5" (88 mm) for fast, touchless reads, and because it is a passive tag it requires no battery or ongoing maintenance—reducing lifecycle costs and administrative overhead. Optional AWID and HID compatibility increases multi-reader interoperability, minimizing deployment friction across mixed-reader installations. Finished in durable PVC with a strong adhesive backing and backed by a lifetime warranty, the PDT-1 is built for reliable day-to-day operation.

Ideal for access control, physical security, and surveillance integrations, the Keri Systems PDT-1 provides a simple, cost-effective credential solution—add it to your next access control rollout or contact sales to order.
