HID Proximity (PROX) card number
HID Prox card number access made easy using SmartCardAPI.
- extracts card number (CN) and facility code (FC) according to card format
- returns raw bit string to extract a number of bits at any offset
- HID PROX card access via managed code
- ProxCardDemo sample code (Visual Studio project)
- supports Windows 10,11
- supports .NET framework 4.6.x and .NET 5.0,6.0,8.0
- tested with OMNIKEY and Elatec readers
No need to sift through HID PROX card and HID OMNIKEY proximity card reader documentation. Nor do you need to look into PC/SC documentation of unmanaged code, write a winscard wrapper in C# or VB.NET etc.
Some readers return Wiegand data via ATR, others via UID, and there are also readers that require proprietary commands.
By the time you are done a week of development time can easily be gone.
Thanks to CardWerk SmartCard API, reading the HID PROX Card Number is quite easy. The sample code shows how to read 26-bit Wiegand data or any other standard prox card format. Wiegand data is parsed according to known card formats.
All you need is SmartCard-API and a few of lines of code read a card number or facility code. This means that you can generate the same Wiegand data, card number and facility code on your desktop system as it is being used in the physical access control panel. Now you can do more with your PROX card than opening doors.
SmartCard API provides you with easy-to-use methods to extract data items such as Facility Code and Card Number.
SmartCardAPI SDK contains a Visual Studio project ProxCardDemo. A few lines of code is all you need to read a PROX card number.
And in case you would like to see the library at work without any coding, download our ready-to-use PACS credential tester for Windows. PACSprobe is available at PACSprobe.com and is based on the same libraries used for ProxCardDemo. However, you don’t need to build the executable first. It is the ideal utility for a quick, free PROX card test just to see if your HID Prox card can be detected. The program calculates the PROX card number applying some known Wiegand encoding formats and supports Windows 10 and Windows 11.
