Payment shock: bank customers could get zapped for overspending

New technology can link wearable device to bank accounts and give electric shocks to help customers manage their spending

Bank customers who overspend could soon get an electric shock to warn them that they have gone into the red, thanks to an invention from a British technology firm.

Zapping someone for going overdrawn might sound harsh, but the company behind the idea claims many customers worried about exceeding their limits would agree that it is better to get a little shock now instead of a nasty jolt later.
