The PRX-C is a non-contact security card that can be used with Viking Proximity Readers to allow entrance into a secure area. These cards are also compatible with certain legacy 125KHz HID® proximity card readers. The PRX-C is a clam shell card made made from 0.070" thick plastic to resist bending and folding. A slot is provided at one end to allow a lanyard to be added for creating a "dog tag" style neck strap.

The cards are pre-programmed with a standard 26-bit Wiegand format consisting of a three digit facility code and a five-digit card number. The range of facility codes is from 2 to 254, and the card numbers range from 1 to 65,534. The actual card number can be printed on a label and placed on the back of each card for easy reference, or the card number can be offset by a fixed value for security purposes.

When ordering, the quantity, facility code, and starting card number along with the card number printing must be specified. Please use the order form located in the Product Manual.
