When Does Billing Seek Credit Card Authorizat

Q u o t e:
Let's say the account was set to expire on the 16th of the month, what day would the billing system attempt to charge the card?

Usually when a purchase is requested our system will contact the bank the credit card is contacted and the amount of the purchase is checked. If the funds are available your bank will hold those funds until the purchase has been fully processed. This usually takes 3-5 business days.

Your bank should honour the purchase for the date it was originally initiated, Forums, but I am not entirely certain how the internal workings of a bank work.
