GLOSSARY
Debit Card
Card that pulls funds directly from a bank account at purchase time.
A debit card deducts funds from the cardholder’s bank account at authorization. It usually has lower interchange than a credit card because no revolving credit is issued.
In some regions, local debit schemes like giro cards ride domestic rails and may not be accepted internationally. Online checkout flows often support debit cards alongside credit to reduce fees and decline rates.
