Along with VR and driverless cars, the Internet of Things is set to play a big role in how technology develops over the coming years.
A new IoT banking platform has been launched by Surrey-based Intelligent Environments, and it includes a wristband that will administer an electric shock when users spend beyond a set limit.
The Pavlock wristband raised £193,000 on Indiegogo in 2014, and works with the IoT banking platform to warn you when you get close to a predetermined limit with a quick vibration.
You can set your own limits using the IoT app, and decide how the program should respond to changes in your bank account.
If you're spending too much money, the app will automatically turn your thermostat down to help you save on energy bills.
All pretty clever stuff, but the guys behind the project are yet to get any banks onboard.
