What is a Debit Card? Understanding debit cards — transaction types, form factors, security layers, and how they power everyday financial activity for billions worldwide.
A debit card is a payment instrument that gives cardholders electronic access to their bank account funds. Unlike credit cards that extend a line of credit, debit cards deduct money directly and immediately from the cardholder's linked bank account — making them the backbone of everyday financial activity for billions worldwide.
