Card scheme

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. By becoming a member of the scheme, the member then gets the possibility to issue cards or acquire merchants operating on the network of that card scheme. UnionPay, Visa and MasterCard are three of the largest global brands, known as card schemes, or card brands. Billions of transactions go through their cards on a yearly basis.
