Almost 1 in 4 US consumers (which equates to 32.6 million households) are unbanked or underbanked. That means these people either have no access to banking products like credit and debit cards, or must pay exorbitant fees to use instruments like prepaid debit cards. (It seems counterintuitive, but the highest fees in the banking and credit industries are charged to those who can least afford them.) Denying these individuals access to basic products and services based solely on payment method borders on discriminatory. It’s one thing for luxury brands to self-select their customers on the basis of price point, but it’s another for a retailer to deny access to a person trying to buy a pack of gum.
