Consumer habits have just taken an interesting turn thanks to recent developments in Japan involving fingerprint shopping. Now, this isn't referring to shopping for fingerprints -- which would seem like an underground business if there ever was one -- but instead shopping by fingerprints. Foregoing cards and chips all together, the country is experimenting with the technology in a few places right now.
Currently available in 300 locations in a handful of areas (Atami, Hakone, Kamakura and Yugawara), fingerprint shopping hopes to expand nationwide by 2020, right when Tokyo is hosting the Summer Olympics. Of course safety and security is also a high issue. People won't like the idea of the government being able to track your shopping habits and more.
