When I wrote about the sharia-compliant credit card in the UAE with a built-in compass so that cardmembers would always know what direction to pray, I said that feature seemed a bit much. And then I realized it helped to solve a practical problem that would give a reason for customers to carry it — and keep it top of wallet.
There aren’t very many practical problems that credit cards can solve beyond payments, rewards, and bundled benefits that aren’t easily duplicated by a smartphone.
Then I was reminded of the 1990 Dana Carvey film, Opportunity Knocks.
