Pay by Link / QR Codes

Pay by Link and QR Code payments enable businesses to request payment by sharing a link or scannable code, often via email, SMS or on-screen display. These methods support instant and remote payments across devices and can include dynamic QR codes linked to real-time payment APIs.

Applications

E-commerce:

Reduces fraud in online card payments by verifying the cardholder's identity

Banking and fintech:

Advantages

  • Enhanced security: Reduces unauthorised transactions by verifying that the genuine account holder is authorising the payment
  • Fraud prevention: Helps reduce chargebacks related to fraud.

Challenges

  • User Experience: Additional authentication steps can cause friction and increase checkout abandonment
  • Implementation complexity: Requires integration with card schemes and issuer systems.
