New NFC Pay / EMV contactless capable readers are being deployed on J Mups systems along with the necessary backend support for VISA / Mastercard / American Express / J Speedy EMV contactless transactions. The flaky old FeliCa only but Apple Pay Suica Express Card dumb JREM readers are being swapped out with ultra reliable Panasonic JT R550CR units.
The finicky UT1-Neo readers used by CardNet systems will also be gradually replaced with new EMV capable UT-X10 readers with the necessary EMV backend support that CardNet announced back in 2015. The current installed base of UT1-Neo readers is 200,000. Hopefully the migration to the new NFC Pay capable devices will not take too long.
J Mups and CardNet are very popular payment systems for smaller Japanese retailers and shops.
