Card networks (or Card Schemes)

Card schemes are payment networks linked to payment cards, such as debit or credit cards, of which a bank or any other eligible financial institution can become a member.

These companies operates a payment card network, such as Visa or Mastercard. These networks facilitate the transfer of funds between card issuers and acquirers.

Card networks impose charges for payment processing and also oversee the determination of interchange fees, influenced by various factors unique to each transaction.

Visa, MasterCard, and Union Pay are three of the biggest worldwide brands recognized as card schemes or card brands. TrustPay is a principal member of all three.
