Going to Japan? Your fingerprint is your new debit card

That's because the government will start testing a new payment system in which tourists verify their identities and pay for goods and services by touching their fingertips against a reader.

The idea is that by eliminating the need to carry cash and credit cards, crime will be reduced.

As The Japan News reports, the system aims to roll out completely by the 2020 Tokyo Olympic and Paralympic Games.

Here's how it will work. As a tourist, you would register your fingerprints and other data like credit card information when you arrive at the airport in Japan.
