Commerce Bank enforces explicit contractual limits on electronic fund transfers and card operations. According to the official personal checking and money market account disclosures, cardholders are authorized to withdraw cash from Commerce Bank's proprietary automated teller machines up to a maximum of $1,000 per business day. Note that dollar limitations and terminal fee structures may differ when using automated teller machines operated by other financial institutions or independent networks. Customers requiring cash over the $1,000 ATM limit can obtain funds via teller services at a physical branch.
