iCLASS SEOS Credentials

PACSprobe now supports iCLASS SEOS physical access control credentials. It extracts PACS bit data from the access control card and applies the appropriate card format to decode facility code and card number


Note that this requires a card reader with on-board SAM (SIO processor). The following readers are supported:

OMNIKEY 5127/5427CK (gen1 and gen 2)

Welcome to the PACSprobe software blog – a blog about probing physical access control cards via desktop card readers. I will publish notes about new releases, interesting features and many other things with regard to physical access control cards commonly used to access buildings and spaces. I am sure many of you are already familiar with physical access control cards a/k/a prox cards or fobs. They are widely used used  to get access buildings secured with physical access control systems (PACS). PACSprobe checks such access cards electronically, using commercial desktop readers in the 125KHz (prox) or 13.56MHz range. So far we have integrated HID OMNIKEY 5025, 5125, 5325, 5326, and 5427 readers. I’ll write about details down the road.
