AVS - AVS stands for address verification system and is one of the many things sites use to verify that the card in question is not being used fraudulently. However, some cards do not have this in place meaning the site is unable to pull up the address the card is registered toBill=ship - One of the most commonly asked questions on TCF and evo. As the system of any site is unable to verify the address you can put any address you like in the billing address section of the delivery form :D. Thisis good news as the billing address differing from the shipping address can throw up major red flags during transactions. With this being said the billing address should always match your shipping address. This is often shortened to bill=ship.VBV - Verified by visa (VBV) is the second stage of the 2-factor authentication system used by visa to try and prevent fraudulent transactions. The first of these is the CVV2 number, which is the 3 digits found on the back of 99% of CC's. Just because a card is non avs doesn't mean it will not have vbv.
BIN - BIN is bank identification number. BINS can be checked by visiting Here and typing the first 6 numbers of your cc in.
