A checkout register at the Lawson Takanawa Gateway City convenience store in Tokyo took a 322-yen payment in the yen stablecoin JPYC on Aug. 6, printing "stablecoin" on the receipt as the payment method, according to CoinPost, whose reporter Ritsuki Kumazawa made the purchase during the demonstration.
Tokyo-based HashPort ran the trial. Customers paid by showing a barcode in the non-custodial HashPort Wallet, which the store's standard point-of-sale register scanned. On the store side, acceptance ran through HashPort Wallet for Biz embedded in that POS, HashPort said, meaning Lawson did not open or manage a wallet itself.
Between the register and the customer's wallet sits PAYTREE, a multi-code payment gateway from Canal Payment Service, which relays the payment data so the wallet provider can check the balance and return an authorization, CoinPost reported. Retail stablecoin acceptance in Japan has until now required either a dedicated payment terminal alongside the normal register or a displayed QR code; this trial added no stablecoin hardware at the till.
The payment settled on Polygon. CoinPost put the gap between the scan and the completion screen at roughly five seconds, an on-site impression rather than a figure released by HashPort or Lawson.
