Since you all seem to know sweet fuck all about how Visa cards work, here's a little schooling.
Merchants have something called floor limits. The floor limit is a maximum amount a merchant can charge to a Visa card without obtaining an authorization. The floor limits are specific to the merchant category and not merchants themselves.
For example (and these numbers are totally made up for example purposes), all grocery stores can process transactions of up to $200 US without requesting an authorization.
When a transaction is passed under the floor limit, no communication is done with Visa before the transaction is completed. The merchant swipes the card the capture the account information for when they do their deposits afterwards.
If a transaction is done under the floor limit, it'll automatically go thru on the account, regardless of whether the account is closed, overlimit, delinquent, been placed on hold, etc. If for any reason the transaction is not valid (for example, a fraudulent transaction), Visa takes responsibility.
On top of that, a merchant can process transactions of any amount without requesting an authorization. However, if the transaction is over the merchant's floor limit and the transaction is invalid, the responsibility for paying the transaction falls on the merchant's shoulders.
So, assuming there was no error on ePassporte's end (for example, the card wasn't placed on hold), the merchant in question most likely never requested an authorization for the transaction.
