SentriCard®

You will use a SentriCard® to access and program lockboxes. A SentriCard® is an ISO 7816 compliant smart card. Unlike their credit card counterparts, smart cards utilize an embedded "chip" that contains the security data for the lockbox system. This chip is immune to magnetic fields as well as employing tamper detection logic and circuitry.

The SentriCard® is the same size as a credit card.
