Some of the main benefits of using a debit card are:
You can enjoy convenience and security, as you can make purchases without carrying cash and benefit from the protection features of your card issuer.
You can track your spending and budget more easily, as you can access your account balance and transaction history online or through an app, and receive alerts or notifications from your bank/financial institution.
You can earn rewards points or cash back, depending on the type and terms of your debit card, which you can redeem for various products or services.
You can avoid debt and interest charges, since you are spending the money that you already have in your checking account.
