Scott: Now this week, we found something that just might revolutionize your lunchroom. Imagine paying for lunch with a wave of your hand. Some California schools have been trying out the lunchroom palm scanner. Students get up to the register, place their palm on the scanner and they are good to go.
Here is how it works: the scanner can take a two-inch image of the vein patterns on your hands, and then assigns each student a unique ID number. So, when it is time to pay for lunch, students just scan their hand and the school’s computer servers locate the student ID.
- What could you use a palm scanner for?
- Is having more biometric technology – devices that recognize you – a good thing, or a bad thing? Explain your opinion.
