Understanding how transactions are processed helps you manage your account balance. Here’s a breakdown of how common payment types affect your Available Balance and Current Balance and what happens if your balance isn’t enough to cover a transaction.
ACH transactions and checks
These are processed in batches and include direct deposits (such as payroll), automatic payments made using your account number (like utility bills or subscriptions) and checks you write.
If your Available Balance is too low when a payment or check is presented, we may transfer funds through Overdraft Protection, pay the item using Discretionary Overdraft, or reject/return it unpaid, which could result in a merchant fee.
ATM withdrawals
ATM withdrawals are deducted immediately from both your Available and Current Balance. If your Available Balance is too low, the transaction will be declined.
Overdraft Protection and Discretionary Overdraft services do not apply to ATM withdrawals.
Point-of-sale (POS) debit card transactions
These include in-store purchases, online shopping and digital debit card purchases. Funds are deducted from your Available Balance immediately. If you don’t have enough funds and Overdraft Protection isn’t active, the transaction will be declined. Discretionary Overdraft does not apply to everyday POS transactions.
Most POS transactions are processed either through a PIN network or the Mastercard® network.
- PIN network (such as Star) transactions are submitted for payment immediately. If approved, the payment is deducted from your account, reducing both your Available and Current Balance at the time of the transaction.
- Mastercard® network debit card transactions are authorized immediately, reducing your Available Balance. However, it may take several days to post and reduce your Current Balance. While the transaction processes, your account will show as a pending transaction or a hold.
If your Available Balance is insufficient when the transaction is presented for payment and posts, your account will still be debited, which may result in an overdraft if you don’t have Overdraft Protection set up.
