Beijing Metro to replace NFC ticket gates with QR codes?

Mobile phone payment to smooth out Beijing subway rides — The Beijinger — “Beginning in May, commuters will be able to pay for their fares on the Beijing Metro by using electronic payment systems like Alipay. All entrance gates to subway stations in the city will be equipped with QR code sensors… The new feature is not related to last year’s feature that allowed Beijing commuters to enter city subways using near field communication (NFC) technology… The Beijing Metro intends to phase out NFC technology at its entrance gates at an unspecified future date.”
