Americans charged more than $6 billion worth of fast food to their credit cards last year compared to $3.7 billion in 2001. Since 2000, fast food sales on credit card have more than tripled even though slightly less than 15% of quick service restaurants currently accept cards. The marriage of fast food and credit cards picked up speed when the processing speeds of such transactions decreased. Typical transaction processing speeds for QSRs have decreased from 20 seconds a few years ago to less than 3 seconds today. Furthermore, studies by VISA on QSR activity show the average transaction for credit customers is 20% to 30% higher than for cash customers. More than half of fast food transactions on credit cards, are VISA transactions.
