Whatever a fintech app does, lending, investing, payments or insurance, it shares a common base: verify who the user is, move money correctly, keep it secure and prove all of it to a regulator. Product features sit on top of that base and fail without it.

01

Onboarding and KYC

Most drop-off in a fintech app happens during KYC. Each extra step costs users, so use the method the regulator permits that needs the least effort.

Mobile and device bindingOTP, SIM binding where required and device registration
PAN verificationName and status check
Aadhaar-based KYCDigiLocker, offline verification or eKYC where the entity is permitted
CKYC lookupReuse an existing KYC record
Video KYCFor full KYC without a branch visit
Bank account verificationPenny drop or reverse penny drop over UPI
Liveness and face matchTo prevent impersonation
02

Payments and money movement

Use licensed partners for regulated activities and design every flow for retries and failures.

Every money-moving request needs an idempotency key. Users double-tap and networks retry.

UPICollect, intent, QR and AutoPay mandates
Cards and net bankingThrough a payment aggregator, with tokenised cards
PayoutsIMPS, NEFT and UPI with status tracking
MandateseNACH and UPI AutoPay for EMIs and SIPs

03

Security features

Security has to be visible enough to build trust and quiet enough not to block honest users.

App PIN and biometricsWith session timeouts
Two-factor authenticationFor login from new devices and for sensitive actions
EncryptionIn transit and at rest, with keys managed separately
Device checksRoot or jailbreak detection, screen-capture controls and certificate pinning
Fraud monitoringVelocity rules, device fingerprinting and alerts

04

Compliance built into the product

Regulatory requirements become product features: disclosures, consents, storage rules and reports.
