A debit card (also known as a bank card or check card) is a plastic payment card that can be used instead of cash when making purchases.

It is similar to a credit card, but unlike a credit card, the money comes directly from the user's bank account when performing a transaction.

A cashback reward program is an incentive program operated by credit card companies where a percentage of the amount spent is paid back to the card holder.

Many credit card issuers, particularly those in the United Kingdom and United States, run programs to encourage use of the card where the card holder is given points, frequent flyer miles or a monetary amount.

This last benefit, a monetary amount, is usually known as cashback or cash back reward.

This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing power.

A credit card is a payment card issued to users (cardholders) to enable the cardholder to pay a merchant for goods and services, based on the cardholder's promise to the card issuer to pay them for the amounts so paid plus other agreed charges.

The card issuer (usually a bank) creates a revolving account and grants a line of credit to the cardholder, from which the cardholder can borrow money for payment to a merchant or as a cash advance.
