First Security Bank sets specific security and operational limits on its debit and ATM cards to safeguard customer funds. Standard consumer debit cards typically carry a daily ATM cash withdrawal limit ranging from $500 to $1,000 per 24-hour period, depending on the specific account type and cardholder credit profile. In addition to ATM restrictions, these cards usually feature a separate higher limit for point-of-sale merchant purchases. Account holders who need to withdraw cash amounts exceeding their standard daily ATM threshold can visit a local First Security Bank branch during business hours for teller assistance.
