A BIN Sponsor has several key responsibilities: Relationship with Networks: The BIN Sponsor manages the relationship with the card networks (e.g., Visa, Mastercard) on behalf of the sponsored entity. This includes negotiating terms, ensuring compliance with network rules, and resolving any issues that may arise. Compliance: The BIN Sponsor is responsible for ensuring that the entire program (including the sponsored entity) is in compliance with all relevant regulations, including those related to anti-money laundering, data privacy, and consumer protection. Financial License: The BIN Sponsor must maintain the necessary financial license to issue cards and process payments. This license is essential for ensuring the security and integrity of the financial transactions. Implementation Support: The BIN Sponsor often provides support to the sponsored entity during the implementation process, helping them integrate with the card network systems and establish the necessary infrastructure. Back-Office Operations: Depending on the capabilities of the sponsored entity, the BIN Sponsor may handle certain back-office functions, such as settlement, chargeback management, and fraud prevention. In essence, the BIN Sponsor acts as a financial intermediary, providing the necessary infrastructure, regulatory compliance, and support to enable the sponsored entity to offer card-based financial services.
