The full answer
A wallet is a ledger with an app on top. We build the ledger first: every credit and debit is a balanced, immutable entry, balances are derived rather than overwritten, and each operation carries an idempotency key so a retried request can never create money or spend it twice. Daily reconciliation against your payment providers and bank accounts is part of the core, not an afterthought.
Typical features include onboarding with KYC tiers and limits, top-ups by card, bank transfer or UPI in India, send and request money, QR code payments at merchants, bill and recharge payments, transaction history, notifications, and a merchant or agent app for cash-in and cash-out. An operations console handles limits, holds, refunds, disputes and compliance reporting.
Wallets attract fraud, so we design device binding, step-up authentication for risky actions, velocity limits, and machine learning signals that flag unusual patterns for human review. Encryption in transit and at rest, role-based access and audit logs are standard, and we run penetration testing before launch.
Wallet licensing and limits differ by country, from RBI rules in India to KNET and local gateway requirements in Kuwait and the Gulf, so discovery confirms which licence or banking partner you operate under before we scope. Consumer apps we have built, such as FlashNow and MakeMyLook, show the checkout and booking experiences a wallet typically needs to plug into.
