About
d Barai (d払い) is NTT Docomo's smartphone payment service in Japan, launched in physical stores on 25 April 2018. The shopper shows a barcode or QR code in the d払い app for the cashier to scan, or chooses d払い at an online checkout, and confirms with a four-digit PIN. Its distinguishing feature is funding: Docomo subscribers can add purchases to their monthly phone bill, while anyone with a d Account can pay from a prepaid d払い balance, a d Card or another credit card, or with d POINT, which the service also earns. Docomo reported 70.04 million users as of September 2025, counting app downloads and iD members.
