Have other alternatives been considered?
The high school I work at here in Australia issues students with barcoded ID cards that act as library cards, concession cards for public transport, and registering attendance. When entering the school, and leaving at any time other than the schedulaed end for the day's classes, they simply swipe the card through a barcode reader and the details are recorded. This system works well and has cut down on time used manually recording attendance. Have similar systems been investigated for Irish schools, or have they jumped straight to biometrics?
