Lock Your EMI Payments
Smartly

LetzPay Locker is an EMI lock and mobile lock system for phone retailers and device-finance businesses. Record the sale and the instalment plan in the dashboard or the retailer app, link the customer's Android handset at the counter, and the phone follows the plan: it locks when a payment is overdue and unlocks the moment the payment is recorded. Everything is managed from one dashboard.

Mobile shops, distributors and device-finance businesses — a single retailer in Dhubri or a dealer network across Assam. If you sell phones on instalments and need the handset to follow the payment plan, this is the software.

The handset runs LetzPay Locker as an Android Device Owner — the same official device-policy framework enterprises use. When an instalment is overdue, the dashboard locks the phone: the customer sees a payment reminder with your shop's contact number and emergency calling stays open. Record the payment and the phone unlocks on its next check-in, or immediately when it comes online. If the phone has no data, the seller can unlock it with a one-time offline code or by SMS command.

Financed phones running Android. iPhones are not supported: iOS does not allow third-party remote lock, so the enforcement point is always the customer's Android handset. Most new Android handsets enrol at the counter; some OEM builds need extra setup steps.

Yes — the dashboard lists every financed device and instalment in one place, with filters and bulk lock/unlock, and a retailer/dealer hierarchy so each shop manages its own customers.

Enforcement runs on Android's official Device Policy Controller APIs rather than accessibility-service tricks, the dashboard is served over HTTPS with authenticated sessions, and phones only act on plans that come from your own ledger. Factory-reset protection is pinned to your shop's Google account, so a wiped phone cannot simply walk away.

At the counter, on a new (or factory-reset) phone: scan the shop's Setup QR — it installs LetzPay Locker and sets it as the device owner in one step. For phones whose setup wizard cannot take the QR, there is an ADB Method over wireless debugging.

The lock comes from Android's device-owner policy, so it survives rebooting and safe mode, and factory-reset attempts are blocked and pinned to your account. Unlocking is only possible from your dashboard or with the one-time offline unlock code the seller issues — not by clearing data or reinstalling the app.
