An Address Verification System (AVS) is a security tool used in online shopping to help prevent credit card fraud. When a customer makes a purchase, AVS checks if the billing address they entered matches the one on file with their credit card company. It's like having a security guard who makes sure the address on someone's ID matches their credit card before letting them make a purchase. This system is a standard part of payment processing in online stores and helps businesses reduce fraudulent transactions and chargebacks.
