Attached is an application I created in Visual BASIC 2005 Express which allows a Parallax RFID Card Reader connected to a PC to read tag data. This application has a small form which allows you to select and open the COM Port for the RFID Card Reader and enable or disable reading as necessary.

By default the RFID Card Reader is enabled when the COM Port is opened. Optionally you can trigger a System Beep during each read. The RFID Card Reader is disabled for 1.5 seconds after a read. This delay is provided to avoid duplicate reads. The RFID Card Reader is then re-enabled. Once tags are read into the Text Box they can be copied into a database or other application, speeding tag entry.
