Card Payments

Card payments cover how you actually use a credit card to buy things—the mechanics of swiping, tapping, or entering your number online, and what happens after. This includes understanding different payment methods, how transactions get processed, and what protections exist when you pay with plastic instead of cash. Readers land here to understand the practical side of making purchases and the rules that govern those transactions.
