all of them? There are several.

Firstit reads the card info from the magstripe, and transmits that info, along with purchase amount, and purchase type ('merchant' for most, but some transactions can be classified as cash withdrawls), then it hits negative auth table that checks if the card is lost or stolen. Then it hits the standard authorization tables and decides whether or not to authorize the transaction based on available balance on the card, and whether or not there are any 'fraud flags' on the transaction - location and merchant type, distance to last spend, international spend, spend in last 6 hours, 24 hours, 48 hours, etc. Then it sends back an approval or denial doe to the POS, and the transaction is either approved or denied, and gives a reason why. Then the transaction is closed with a 'resolution code' that confirms that the transaction that was approved actually took place.
