With all due apologies to The Graduate, the plastics McGuire advised Benjamin about should have been the plastics that make credit cards. With the wholesale adoption of eCommerce, the basic reality of retail sales has changed and credit/debit cards are the outward expression of that change.
Obviously, online retail has little option other than to accept credit cards. PayPal and Microsoft Wallet are options but are too limiting for their customer base. Reflecting that, PayPal offers a debit card to access your account with which makes it much more convenient, both online and at brick-and-mortar retail stores. If PayPal, a leader in online payment systems, offers both credit and debit cards, it’s time to reevaluate your business decision to not accept electronic payments.
