Wink uses in-app nudges to guide merchants through integration setup and drive adoption of new payment methods
Digia Engage powers step-by-step merchant onboarding sequences, feature discovery bottom sheets, and fraud alert widgets inside the Wink dashboard.
About Wink
Wink is a modular payments platform connecting identity, risk, and commerce in a single stack. The platform powers biometric checkout (face, palm, voice), payment orchestration across 200+ gateways, AI-powered fraud detection, and age verification.
- Biometric checkout: face, palm, and voice authentication
- Payment orchestration across 200+ gateways
- Integrated with Fiserv/Clover, SUNMI, PAX, and Qualcomm
The Challenge
Wink's merchant onboarding is complex. Each integration partner (Clover, SUNMI, PAX) requires custom setup flows with different API configurations, compliance steps, and go-live checklists.
- Every onboarding variation required native development. The product team wanted step-by-step guidance inside the app.
- When Wink launched a new biometric checkout option, existing merchants did not discover it. The feature sat in a settings menu with no way to surface it at the right moment.
- White-label customisation requests went through the engineering queue, slowing merchant activation
The Solution
- Step-by-step onboarding nudge sequence: after sign-up, the app shows a progress widget ("Connect your POS", "Configure payment methods", "Run a test transaction", "Go live"). Each step triggers a nudge specific to the merchant's hardware partner.
- Feature discovery bottom sheets that surface new payment methods at the right moment. When a merchant hits a volume threshold, a nudge introduces biometric checkout with a one-tap setup flow.
- Fraud alert inline widgets in the merchant dashboard when unusual activity is detected, with a direct link to review flagged transactions
- White-label configuration through in-app widgets where merchants adjust checkout branding. Changes apply immediately without an SDK update.
Impact & Results
- Merchant onboarding completion improved — step-by-step in-app nudges replaced static documentation
- New payment method adoption increased — contextual feature discovery surfaces options when merchants are most likely to act
- Partner-specific onboarding managed from the dashboard — not the codebase
- White-label customisation without engineering tickets — merchants adjust branding through in-app widgets
