Cash is being displaced in so many ways that it’s hard to keep track. There are credit cards and electronic payments; apps such as Venmo, PayPal and Square Cash; mobile payments services; cryptocurrencies that operate outside the purview of central banks; and localized offerings such as Kenya’s mPesa, India’s Paytm and Bangladesh’s bKash. These innovations are encouraging cashlessness across communities worldwide. Cash will likely become less popular, thanks to the high cost of using cash and the growing array of alternatives. But I expect it will remain with us forever. The future will be “less cash,” rather than cashless.
