Paradox Proximity (C702 / C704 / C705) Compatible Cards & Fobs
Paradox proximity credentials (C702 card, C704/C705 fob) use 125 kHz 24-bit encoding — AKC supplies compatible replacements without OEM pricing.
Paradox Security Systems' proximity credentials run on standard 125 kHz RFID technology with a proprietary 24-bit format, making them fully cloneable and replaceable with compatible aftermarket cards. American Key Cards programs and supplies Paradox-compatible clamshell cards and keyfobs for Digiplex and Magellan system users, saving dealers and property managers the OEM markup on routine credential replacements.

Our compatible Paradox Proximity (C702 / C704 / C705) credentials
American Key Cards manufactures non-OEM credentials engineered to work with your existing Paradox Security Systems readers — no hardware changes, encoded to your facility code and card-number range.
Can Paradox Proximity (C702 / C704 / C705) cards be copied?
Paradox Proximity (C702 / C704 / C705) is an open format, so a compatible card can be produced from your facility code and card number. We don't copy individual cards on request — we manufacture new, correctly-encoded credentials for systems you own or manage.
Paradox proximity credentials operate at 125 kHz using a 24-bit encoding scheme. Like all 125 kHz prox technologies, they carry no cryptographic protection and can be cloned with Proxmark3 or T5577 blanks. Paradox panels also support higher-security smart card readers for sensitive installations.
Where Paradox Proximity (C702 / C704 / C705) is used
- Residential and small commercial Paradox alarm/access hybrid systems
- Multi-unit residential complexes running Digiplex or Magellan controllers
- Replacement fobs for C704/C705 teardrop keytags lost by tenants
- Retrofit installations requiring additional Paradox-encoded credentials

What chip format do Paradox C704 and C702 proximity credentials use?
Paradox proximity cards and fobs (C702 clamshell card, C704 teardrop fob, C705 flat fob) operate at 125 kHz using Paradox's 24-bit encoding. Credentials are sequentially numbered and encoded at the factory.
Can American Key Cards supply a replacement for a lost Paradox C704 fob?
Yes. Send us a working fob or your credential list and we will program compatible 125 kHz fobs encoded to the same Paradox 24-bit format. They read on Paradox proximity readers without any panel reprogramming.
Do Paradox readers also accept standard 26-bit HID cards?
Some Paradox reader configurations support standard 26-bit Wiegand output, depending on how the panel is programmed. Contact us with your panel model and we can advise whether a standard H10301 card will work in your installation.
