Forget having to pull your wallet out of your pocket ever again. For foreign tourists coming into Japan, the country is currently undergoing testing of a new payment and identification method that requires only your fingerprint.

Some companies are already finding ways to phase out the credit card. But the entire country hopes to implement fingerprinting just in time for the Tokyo 2020 Olympics.

The Perks

When you arrive in Japan as a tourist, you place two fingers on a designated scanner (at the airport or elsewhere). This registers your fingerprints and other data, including credit card information. You only need to scan your prints once, and you’re good to go.

As of now, there are 300 souvenir shops, restaurants, and hotels in Japan that are currently experimenting with fingerprinting. They’re predominantly in popular tourist areas such as Kamakura, Hakone, and Yugawara in Kanagawa Prefecture. By next spring, the list of participating regions and prefectures will enlarge. By 2020, the Japanese government plans to recognize this method across the entire country, in the hopes of drawing in 40 million foreign tourists.
