Taken from this google alert:
Seven & I Holdings Co. (3382.TO) said Friday that it will set up e-money reader terminals at its group stores starting this autumn in a bid to lay the groundwork for accepting different types of electronic cash.
The Japanese retail giant, which operates Seven-Eleven convenience stores in Japan, said it will install "multi-reader writers" in registers at 11,000 of its stores. The reader system, developed by Matsushita Electric Industrial Co. (6752.TO), will allow customers to pay with Seven & I's "nanaco" prepaid e-money available next year, as well as with JCB Co.'s QUICPay pay-later e-money service.
So Japan is well up to the non-cash e-money types. And in doing so the Japanese market is living proof of the inevitable interoperability and acceptance of multiple cards at one location.
