For small transactions, the transaction will likely still occur off-line, going online seconds, minutes or hours after the transaction, depending on the vendor, card and the parameters of the application stored inside the card - the retailer will have a floor limit, and so does your card, so purchases over a certain value will take longer than purchases under a certain value. On some cards this limit may be set to zero. The terminal will not know the value, it will just process the result of the transaction certificate.

The prepaid cards do not have any floor limit at all. On my Paytag I've seen it go online for 99p.
