You probably know that when you use a credit card to buy something the merchant pays a fee based on a percentage of the item’s cost. This gets passed on to you in higher prices. Ever wander how much higher? This calculator/mashup will tell you. I tried one of my cards (enter the first six digits of the account number which identifies the issuer and type of card) which is from Amazon where I get a $25 certificate for each $2500 I charge. Turns out reward cards like that cost businesses even more. Might want to think about that when buying from a small merchant.
Rewards cards cost businesses more than non-rewards cards because the credit card issuers pass the cost of the rewards onto the businesses by charging them higher Interchange rates. Rewards interchange rates are typically around 0.30% higher than the rate for a regular card. However, many smaller businesses actually get charged more than 0.30% additional for such transactions because it triggers a downgrade, which allows their credit card processor to charge them as much as an additional 1.50%.
It appears people are using credit cards less in this recession. But some are worried the credit card debt poses a bigger problem than the mortgage crisis.
