I would like to initiate a project with RF ID, which allow us to monitor our packages (Bags / Packaged Items) Entry / Exit. Each time they cross the door, it would automatically enters the record on the system database.

Our project is in PHP. So I would like to have your kind suggestions and recommendations about relevant RF ID Device and PHP Codebase /SDK / Library.

All kind suggestions are welcomed.
