What is the Kantech eXtended Secure Format (XSF)?

The Kantech eXtended Secure Format, or XSF, is Kantech’s proprietary credential format for their line of ioProx proximity cards, key fobs, and tags compatible with their line of ioProx card readers. The ioProx credentials and card readers use Kantech’s EntraPass access control software to verify the user's identification.

The Extended Security Format is a 26-bit format. Kantech also offers the KSF or Kantech Secure Format, a 34-bit format compatible with HID and Shadow Prox readers.

Advantages of XSF

Kantech’s XSF cards are advantageous because they can be encoded with over 4 billion unique credential codes thanks to the combination of Family Code, Facility Code, and Card Number. With this many codes, your business is guaranteed never to run out of identification numbers. The Family Code could be especially useful for large corporations with multiple subsidiaries.

Besides the billions of unique codes, this format is compatible with a host of ioProx 26Bit card readers and various credential types, so your business can choose the exact configuration that suits your needs. This includes Kantech’s proprietary offerings but also compatible non-proprietary 26-bit card options that are usually associated with improved customer support and cost savings.

The eXtended Security Format offers Digital Signal Processing (DSP) that ensures rapid and reliable credential verification.

XSF Card Reader Compatibility

All ioProx card readers are compatible with cards using Kantech’s proprietary eXtended Secure Format (XSF) cards and the popular Weigand 26-bit format. This includes dual-encoded cards using these two formats. Kantech’s ioProx cards can also be combined with a PIN number request to add another level of authentication.

 ioProx readers can be installed in interior or exterior environments because they are highly durable and resistant to vandalism. Readers contain a bi-color LED that displays green when a card is successfully authenticated or red when it’s not. All of Kantech’s readers integrate with Kantech’s access control software, EntraPass.

Customers can select from a single gang box or mullion card reader, depending on mounting preferences. Here are the Kantech card reader options:

  • Mullion Mount Reader P225XSF
  • Mullion Mount Reader with Keypad P225KPXSF
  • Single Gan Mount Reader P325XSF
  • Single Gan Mount Reader with Keypad P325KPXSF
  • Long Range Reader P600

What credentials work with Kantech?

Kantech’s ioProx readers are compatible with several credential types, including cards, fobs, and adhesive tags. Kantech has 5 proprietary credential selections for you to choose from:

P10SHL Clamshell Card – not printable, available with vertical slot punch

P20DYE ISO-Thin Card – printable on both sides, available with vertical or horizontal slot punch

P30DMG ISO-Thin Card with Unencoded Magnetic Stripe – printable on both sides, available with vertical or horizontal slot punch

P40KEY Key Fob Tag – not printable, comes with a key ring hole

P50TAG ISO Self-Adhesive Round Tag – not printable, has no slot punch because it is attached to a personal item like a phone, id card, or wallet using the adhesive backing.

Besides these proprietary cards, key fobs, and adhesive tags, you can also purchase non-proprietary proximity cards, other credentials, and accessories (like wristbands) that are compatible with ioProx 26Bit format. Selecting non-proprietary options usually results in major cost savings, especially when buying large volumes.

Figuring out the Family and Facility code for your Entrapass system

Need to order new ioProx cards, but don’t know your Family Code or Facility Code? We can help with that.

If your organization is already using the Entrapass system, it’s super easy to figure out the family and facility code by looking at any existing ioProx proximity card in your system. Along the side of the card you’ll find a series of numbers and letters.

The XSF code lets you know your existing cards are ioProx Extended Security Format cards. Then you’ll see a number within quotation marks, this is your Family Code. And finally, your Facility Code is made up of the numbers between the quotation marks and colon.

Here’s how it should read:

XSF (Family Code) Facility Code : Card Number
