How many prox cards will you need per year?


When ordering prox cards, there is some information you need to provide and many options to choose from so you can get custom cards designed specifically for your organization. To order cards, however, you’ll need to understand what all those choices are – so let the experts at Prox Source help by explaining all your proximity card options.

  • Types of Prox Cards

    Proximity cards come in a wide range of styles from standard blank cards to printable cards, dual-encoded cards with magnetic stripes, key fobs, thick clamshell cards, and more.

  • Prox Card Brands

    Prox cards are available from a wide range of brands - although HID was the first manufacturer, there are now many other options with different card types and price points to match any customer's needs.

  • Prox Card Formats

    The card format describes the data pattern programmed on your cards, and the compatibility with card readers. All prox cards use a radio frequency of 125 kHz to transmit their data to the card reader.

  • Prox Card Facility Code

    Each access control system has a facility code, that identifies your proximity system. This code is represented as a number between 0 and 255.

  • Prox Card Sequence

    Every prox card has a unique card ID number, called a sequence number. You cannot repeat sequence numbers, since duplicate cards will not work. Numbers are between 0 and 65,435.

  • External Printed Number

    By selecting to print the card sequence numbers on your prox cards, each card's unique sequence number is easily visible so you can identify a card and know who that card belongs to in the case of a lost card.

  • Slot Punches

    Slot punched cards attach to lanyards, badge reels, key rings, or other card accessories for easy card access. You can choose to have the manufacturer slot punch them for you, or slot punch them yourself.

  • Custom Pre-Printed Cards

    Customizing your prox cards with artwork allows you to use them as employee IDs, membership cards, security passes, and more. To order these cards, you will need to submit your card design to the manufacturer.
