This article investigates the degree to which buyers choose to diversify their use of payment methods for in-person purchases. Some buyers use only one payment instrument. Others combine the use of mostly cash, credit, and debit cards, and a few paper checks and prepaid cards. To each survey respondent, I apply three concentration and inequality measures over the use of payment instruments. Results show that the average and median degree of consumers' payment concentration only slightly decline with payment volume and exhibit almost no correlation with consumer demographics.
