IssuerBank

IssuerBank is a financial institution that issues payment cards on behalf of card networks to consumers and businesses. It underwrites the card accounts, sets credit limits or debit funding, and assumes payment risk.

In the payments ecosystem, the issuer interacts with cardholders, merchants via acquirers, and networks. It authorizes or declines transactions, manages risk, and settles funds with merchants through the acquirer.

Typical products include credit cards, debit cards, and prepaid cards. The issuer may provide rewards programs, customer service, statements, dispute handling, and digital wallet integration.

Operations: underwriting and risk management; fraud monitoring; compliance with KYC/AML and data security; operations in collaboration with payment processors to handle authorization and settlement.

Regulatory and market context: regulated by financial authorities; subject to capital and conduct requirements; consumer protection; adherence to network rules; fee structures like interchange and issuer processing fees.

Issuer banks collaborate with card networks such as Visa and Mastercard to issue cards and access network rails, and with acquiring banks to settle merchant transactions.
