Mastercard debit payment issue

[keld1]

Hello, yesterday I tried purchasing a voucher online for my pre paid account using my bmo Mastercard debit card. The transaction kept saying there was an error. Today i notice a charge of $1 from Rogers each time i tried to pass the card. So is my card now going to be charged 3 times for the voucher. I hope not as I did not want to purchase 3 vouchers and as the transaction said failed I assumed it was which is why i tried a couplew other times.

Hi @keld1,

The $1 charge is actually a temporary preauthorization from your credit card company, basically giving the merchant (Fido) the green light to charge your card for the full amount when your final purchase is made. By preauthorizing your card $1, they don’t have to place a larger hold against your account.

The $1 charge disappears when the final amount you’ve spent is no longer pending, the preauthorization is lifted and the $1 charge doesn’t show up on your final statement.
