About
au PAY is the smartphone code-payment service of KDDI Corporation, the Japanese telecom operator behind the au mobile brand, launched in April 2019. In stores the shopper pays with a barcode or QR code in the app, and the payment draws on a prepaid au PAY balance that can hold up to JPY 1 million. That balance can be topped up from a credit card or au Jibun Bank account, by adding the charge to an au or UQ phone bill, with Ponta points, or with cash at Lawson Bank and Seven Bank ATMs, Lawson stores and au shops. Although it grew out of the au carrier ecosystem, anyone with a smartphone can use it.
