Credit cards are more convenient than bulky cash, and can be used worldwide without the need for currency conversion - a real boon to travelers. For online, catalog, and television shopping, credit cards offer much speedier service than checks, which can delay order fulfillment until the check clears.

Credit cards can also be used to pay for purchases of merchant services sales training widely varying amounts, which means customers who use them don't have to bother with making detailed shopping lists and plans before they hit the stores. It also means that customers who use credit cards have a greater degree of altitude when making impulse purchases. Rather than being bound by the cash in their pocket or purse, credit card users can buy items they see which they might not otherwise have planned on purchasing.

Retailers also benefit: credit card users make more costly impulse purchases, and more frequent impulse purchases, than those shoppers who use cash, meaning your profits can be significantly increased with credit card sales.
