A new product will help us save money. It is a wristband called the Pavlok. It knows how much money we have in the bank. It gives us a small electric shock if we buy something but do not have enough money. In the future, many banks could give the Pavlok to their customers.

The Pavlok is part of the Internet of Things. People like it. Shoppers said it is better than getting a big shock from credit card bills. It is good for people who cannot stop spending – people with no willpower. Many young people buy too many things. They don't think about what is in their bank.
