Your debit card has no annual fee and no fee for purchases. The only exception is if you use your card while traveling in another country, or to make a remote purchase from the United States with a foreign merchant, in which case a foreign transaction fee will apply, regardless of whether a currency conversion is required. If you use your debit card at another financial institution’s ATM, a fee may apply. Please see your Deposit Account Agreement for more information on fees.

Remember, BMO Harris debit card customers get unlimited fee-free transactions at over 40,000 BMO Harris and Allpoint^® ATMs nationwide.  Footnote 2²

You can use a debit card just like a credit card wherever Mastercard^® is accepted. The difference is, when you use a debit card the money is deducted directly from your BMO Harris checking account, so you don’t owe anything after. It’s a great way to manage your money and avoid building up credit card debt.

When you use your debit card to make a purchase, the merchant will request an authorization — in other words, an approval — for the transaction to confirm that your account is open and has enough money in it to cover the amount. A merchant hold or authorization hold simply means that the amount of the purchase has been set aside in your account — it is, ‘on hold’ as a pending transaction. It will stay on hold for up to 3 Business Days if you made the purchase in person, or up to 5 Business Days for online, phone or mail order purchases. Once the transaction goes through, the actual purchase amount will be deducted from your account. It may take several Business Days for the final purchase amount to replace the pending transaction amount on your account.

If you have an issue with a purchase you made, please contact the merchant. If you need further help, please call us at 1-888-340-2265.
