Now Japan is trying out a new idea:
Fingerprints to be tested as ‘currency’
Starting this summer, the government will test a system in which foreign tourists will be able to verify their identities and buy things at stores using only their fingerprints.
The government hopes to increase the number of foreign tourists by using the system to prevent crime and relieve users from the necessity of carrying cash or credit cards. It aims to realize the system by the 2020 Tokyo Olympic and Paralympic Games.
The experiment will have inbound tourists register their fingerprints and other data, such as credit card information, at airports and elsewhere.
Can’t wait for it to hit the U.S. Then again, maybe I can….
