Innovators in Japan hope to execute a revolutionary idea before the 2020 Olympics: replacing credit cards and cash with fingerprints! The new system will be able to determine a person’s spending money via their fingerprint, and will conveniently require only one scan upon entering the country. All the customer would do to pay is undergo fingerprinting on a scanner by placing two fingers down, and they would be good to go, barring any lack of funds, that is.

This technology already exists in several businesses in Japanese prefecture Nagasaki, but the government now hopes to expand the fingerprinting locations to 300 popular businesses in tourist areas as an initial experiment. The idea is a huge draw for tourists because it would eliminate the need to fill out tax exemptions, and would only require passport identification for certain purchases. With the goal of setting up fingerprint payment infrastructure all around the country, Japan hopes to attract 40 million visitors to the 2020 Olympic Games. The initial experiment will provide information about the feasibility of the idea that will help officials improve the system over the next four years. Though critics doubt people’s willingness to submit fingerprints, Japanese bank Aeon is fully in support, and even hopeful that fingerprinting will increase security and cut down on fraud.
