THE CHALLENGE
Cloakrooms still run on staff, tokens and cash
Cloakrooms and luggage lockers at railway stations, temples, beaches and malls still run on staff, paper tokens and cash. Queues build at peak hours, keys get lost, and owners cannot see how many lockers were rented or for how long.
WHAT IT DOES
What it does for you and your customers
RNDSquare designs the controller for your locker bank. It drives each door’s lock over RS485 and senses when a door is open, with a central QR screen or a printed QR on each door. It runs on 4G with Ethernet backup and battery backup, so doors keep working through power cuts. We also build the application support: pricing by locker size and duration, peak-day rates, one-time codes to reopen a locker, overstay charges, and staff overrides with an audit trail.
Accept UPI from any app
The visitor picks a size and duration, pays, and the locker opens.
Sound confirmation
The unit announces the payment as the door unlocks.
Instant refund on service failure
If the locker does not open after payment, the visitor is refunded automatically.
Hosts receive payments within 24 hours
Site owners and operators get each day’s rentals the next day.
Full application development
Live occupancy per locker bank and per site is built for you.

FAQ
Questions buyers ask us
How does a UPI smart locker work?
The visitor picks a locker size and duration, pays from any UPI app, and the locker opens as the unit announces the payment. A one-time code lets them reopen it later.
What happens during a power cut?
The controller has battery backup, so doors keep working through power cuts. It runs on 4G with Ethernet as a backup connection.
What happens if the locker fails after the customer pays?
If the locker does not open after payment, the visitor is refunded automatically.
When do owners receive the money?
Site owners and operators receive payments within 24 hours. Each day's collections arrive the next day, with a settlement report.
