OCPP & UPI mobile payments
Digital payments are rapidly becoming the preferred method for everyday transactions around the world, including EV charging. That’s why OCA has published a whitepaper on UPI (Unified Payments Interface) in collaboration with the India Smart Grid Forum.
UPI is widely used in India and enables instant account-to-account payments using QR codes or mobile apps. It has transformed digital transactions, offering instant, 24/7 payments directly between bank accounts. This capability makes it a natural fit for public EV charging, where drivers can pay quickly without the friction of cards, wallets, or cash.
Our whitepaper explores how UPI can be integrated into EV-charging payments, looking at both simple and advanced integration models. It highlights how OCPP supports these scenarios through features such as remote transaction control and prepaid transaction limits.
