Paradox Security Systems Compatible Cards & Fobs

Paradox Security Systems is a globally distributed alarm and access control brand with strong residential and small commercial presence, using a proprietary 24-bit 125 kHz proximity encoding on its C702 card and C704/C705 key fob credentials. American Key Cards programs and supplies Paradox-compatible clamshell cards and key fobs for Digiplex and Magellan system users, saving dealers and property managers the OEM markup on routine credential replacements.
