Palm Biometric Payments
Authorise payments and verify identity using palm vein biometrics, without cards, phones or PINs.
The challenge
Card and PIN-based payment verification adds friction at physical points of sale and remains vulnerable to theft, cloning and shoulder-surfing. Biometric alternatives such as face or fingerprint can raise privacy concerns or hygiene objections, creating demand for a contactless option that does not require carrying a device.
Key capabilities in this use case
Palm vein enrolment
Register a customer's unique palm vein and print pattern once, linking it to their account for future authorisation.
In-store payment authorisation
Let customers authorise a purchase with a palm scan at the point of sale instead of a card or PIN.
Identity verification at entry points
Use the same palm biometric for secure physical access or identity checks beyond payments.
Device-free experience
Enable authentication without requiring the customer to carry a phone, card or token.
Core capabilities
Palm vein biometric matching
Verifies identity from vein and print patterns.
Payment authorisation flow
Links biometric verification to a payment transaction.
Enrolment management
Handles onboarding and re-enrolment of biometric profiles.
Physical access use
Same enrolment can extend to entry and access scenarios.
Enabling contactless palm payments in-store
A retail chain wants to offer a faster checkout option that avoids fumbling for cards or phones at busy tills. It rolls out palm vein enrolment kiosks in flagship stores, allowing customers to register their palm biometric once against their loyalty and payment account. At checkout, a customer simply presents their palm to a reader to authorise payment, with the biometric match completed in the time it takes to scan a barcode. The retailer retains its existing payment processor, with Authsignal handling the biometric verification and authorisation step in the transaction flow.
- 1Customer enrols palm biometric once via in-store kiosk
- 2Palm scan presented at checkout to authorise payment
- 3Transaction proceeds through existing payment processor
Expected outcomes
- Faster checkout with reduced friction
- Lower reliance on cards or phones for payment
- Reduced exposure to card cloning and PIN theft
- Reusable biometric enrolment for access scenarios
How CyberLane helps
CyberLane advises retailers and payment teams on evaluating palm biometric deployment, including enrolment logistics, privacy considerations and integration with existing point-of-sale and payment systems.
- Palm biometric feasibility assessment
- Privacy and consent framework review
- POS integration planning
- Pilot store rollout design
CyberLane is independent and works on the decision rather than the deployment. Product-specific delivery is coordinated with the vendor or a qualified implementation partner.
