Everyone pays by card these days. (Indeed this professor is driven nuts in Starbucks by customers using this method to pay for a coffee – has no one under thirty heard of cash?). Most of us use a chip and pin debit or credit card – that’s to say a card which requires us to punch in a PIN number when inserted into a terminal. But some people, especially the visually impaired, find this method difficult to use.
However there is a little known alternative – the chip and signature card. Upon payment, this card does not require the customer to enter a PIN, but to write their signature. With an aging population, this method of payment is likely to be seen much more often, especially in retail outlets that serve this market.
