High-tech Cheating on Exams

India is cracking down on people who use technology to cheat on exams:

Candidates have been told to wear light clothes with half-sleeves, and shirts that do not have big buttons.

They cannot wear earrings and carry calculators, pens, handbags and wallets.

Shoes have also been discarded in favour of open slippers.

In India students cheating in exams have been often found concealing Bluetooth devices and mobile SIM cards that have been stitched to their shirts.

I haven't heard much about this sort of thing in the US or Europe, but I assume it's happening there too.
