Comments: This software was created in Filemake Pro. The main window MUST stay in full screen mode in order for it to detect and respond to a card scanner and unlock a security door. No minimizing of screens or multitasking allowed. It requires a dedicated Windows PC. If you are entering a new client and someone scans their card at the same time all the fields in the new client screen will be filled with the name of the person who scanned their card. This is TERRIBLE software, poorly thought out, with a horrible menu navigation. Any updates will totally wipe out all previous clients and they must be re-entered manually. AVOID AT ALL COSTS!
