UPI payment module for AC EV chargers
A UPI payment module turns each AC charger into a pay-and-charge point that anyone can use.
THE CHALLENGE
Chargers where vehicles park for hours, with no way to take money
AC chargers sit where vehicles park for hours: apartments, offices, hotels, malls and public parking. Most have no screen and no way to take money, so apartment associations split bills by hand, hotels give charging away, and visitors cannot use a charger tied to an app they do not have.
WHAT IT DOES
What it does for you and your customers
RNDSquare designs a compact payment module that fits inside your AC charger or on its mounting plate. It shows a QR code per connector on a small display, or as a printed QR with a status light, and connects over 4G or Wi-Fi. It reads energy from your charger’s meter and works over OCPP or as a standalone controller. We also build the application support: per-kWh or hourly tariffs, separate rates for residents and visitors, monthly statements for building managers, and an owner dashboard.
Accept UPI from any app
The user chooses an amount, energy or time, then scans and pays.
Sound confirmation
The charger announces the payment and switches on.
Instant refund on service failure
If charging does not start, the user is refunded automatically, and unused balance is credited back.
Hosts receive payments within 24 hours
Building owners and associations get their collections the next day.
Full application development
Usage tracking per user and per charger, statements and tariff control are built for you.

FAQ
Questions buyers ask us
How can an apartment charge residents for EV charging with UPI?
Each AC charger gets a UPI payment module with a QR code per connector. Residents and visitors scan, pay for an amount, energy or time, and the charger switches on. Building managers get monthly statements and the association receives collections the next day.
Does the AC charger need a screen?
The QR code can appear on a small display, or as a printed QR with a status light. The module connects over 4G or Wi-Fi and reads energy from the charger’s meter.
Can residents and visitors pay different rates?
Yes. The application supports per-kWh or hourly tariffs with separate rates for residents and visitors.
When do owners receive the money?
Building owners and associations receive payments within 24 hours. Each day's collections arrive the next day, with a settlement report.
