Which banks can issue unlimited number of virtual cards? Affiliate.

 As of my last knowledge update in January 2022, there aren't many banks that issue an unlimited number of virtual cards for affiliate programs. Additionally, the policies and offerings of banks can change, and new services may emerge. It's important to check with specific banks or financial institutions for the most up-to-date information on their virtual card services and affiliate programs.

Some banks may offer virtual cards as part of their business or corporate banking services, but the issuance limits may vary. Additionally, dedicated fintech companies and online payment platforms may provide virtual card services with different terms and conditions.

Keep in mind that unlimited issuance of virtual cards may not be a common practice due to security and regulatory considerations. It's advisable to thoroughly review the terms and conditions, as well as any associated fees, before choosing a bank or financial service for virtual card issuance in the context of affiliate programs.
