It’s been so long since 30-year-old Cape Town entrepreneur Kobus Ehlers last used his wallet that he’s not even sure where it is. “My car maybe?” he says as he reflexively scans the cheerfully decorated offices of his startup, SnapScan. When it’s pointed out that leaving a wallet in a car in a city infamous for break-ins and carjackings may not be a good idea, he shrugs. He probably doesn’t even have the equivalent of five dollars in it, he says. “I never use cash. Credit cards are over. There are much better ways to pay for things.”As the co-founder of one of South Africa’s most successful electronic payments apps, Ehlers is of course expected to use his own product. But the real reason he isn’t worried about his wallet is because Cape Town is a city seduced by the idea of cashless and cardless transactions, in no small part because of his company’s success. “You can literally wake up in the morning, buy a cup of coffee, go to your dentist, have lunch, pay your bills, take a taxi, go out for dinner, and donate to your favorite cause without using cash or a card,” says Ehlers. “And in none of that is there any risk of your card details getting stolen, or you getting mugged for your cash.”
