I had never heard of biometric finger scanning until my son’s school sent home a permission form. Apparently the technology has been around for several years to monitor school attendance and checkout library books. Seems like a good idea to me. Parents who elected to opt out of the system were told their children would be issued with cards. I would like to see the biometric system introduced at my workplace. I have four different cards for the three offices I have to work from and the carpark. Cards can be stolen, but my finger is going nowhere I don’t want it to go.
