The article mentions cards linked to a customers checking account. I assume that means a "debit card", i.e. one where transactions are deducted immediately rather than aggregated into a monthly bill? How common are those cards in the US?
Here (.se), most Visa and Mastercards are bank-issued debit cards, and almost everyone would have such a card, even if they also have a credit card from Visa/MasterCard. Is the situation the same in the US?
