This wristband will give you a 255-volt shock when you spend too much money

What better way to save for that new TV than by getting an electric shock every time your bank balance drops?

If you're struggling to save cash for your holiday, perhaps the Pavlok wristband is the thing for you.

This wearable device can be linked to your bank account and will deliver a 255-volt shock to your arm when your account drops below a pre-set amount, the BBC reports.

"Willpower is great if you've got it -- not everybody has," said David Webber, CEO of Intelligent Environments, the banking technology firm behind the prototype.

Pavlok, the maker of the hardware, has previously used its technology to help you get out of bed in the morning and to avoid procrastinating on the Internet.

So far, no banks have signed up to offer the band. For now, at least, you'll have to figure out your own ways of controlling your shopping sprees.
