Checkout

Checkout refers to the user experience and the process by which customers complete a purchase on an e-commerce website or application. It involves entering payment details, confirming the order, and processing the transaction. Typically checkouts are supported by a specialist Payment Service Provider (PSP) allowing the seller to use an off-the-shelf software to integrate their e-commerce, payment acceptance and banking requirements in a way that encourages a fast and seamless purchase.

Applications

E-commerce:

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

  • Fraud prevention: Helps reduce chargebacks related to fraud.

Challenges
