Wink Verified
A device or model is "Wink Verified" when it meets these criteria:
Use Cases
Connect to your current payment processor, acquirer, and POS system.
Wink layers in on top — no migrations, no new contracts, no downtime.
Frictionless
Customer Checkout
Returning customers authenticate with face or palm for instant account-linked checkout. Eliminates card fumbling and speeds up lines during peak hours.
Loyalty Recognition
at POS
Recognize enrolled customers the moment they approach the counter. Automatically apply rewards, discounts, or personalized offers without manual lookups.
Employee
Access Control
Authenticate staff at the device level to control Clover permissions, track time-on-terminal, and eliminate credential sharing between shifts.
Age-Restricted
Product Sales
Verify customer age in real time for alcohol, tobacco, cannabis, or other restricted items—fully compliant and audit-ready.
Fraud Prevention
Combine biometric liveness detection with Wink's AI fraud scoring to reduce chargebacks and block account takeover attempts at the POS.
Drive-Thru & Curbside Authentication
Recognize returning customers at drive-thru windows or curbside pickup with Clover Kiosk or handheld devices.
