Regulation E protects consumers who use electronic fund transfers. As a FinTech, you are responsible for assisting customers who report errors impacting their account balances or unauthorized transactions. Regulation E covers electronic fund transfers including point of sale purchases, ATM withdrawals, ACH transfers, and overdrafts. It requires disclosures of fees and limits, as well as procedures for error correction, liability, preauthorized transfers, and receipts. Transactions not covered include paper checks, wire transfers, and intra-bank automated transfers between a consumer's accounts at the same bank.
