Tap to hail

摘要

Since last month the citizens of Johannesburg have been able to hail and pay for taxis through SnappCab, a local start-up. A tap on SnappCab's smartphone app summons a cab; a driver accepts on his own phone; and the passenger sees the driver's name and photo, so he knows whom to expect and when. At journey's end, he can pay with another tap through a pre-loaded credit card, or in cash. The idea is simple: the app makes it easier to bring together drivers, whose cabs are often empty, and passengers. Time and fuel are saved.
