This is the first of three blogs about technologies to support contact-free use of public transport.
I heard on the radio that, despite ministers encouraging people in England back to work in their offices, most are staying at home. Commuter trains are about one-third full and buses are about 40% full. During the COVID-19 pandemic, demand for public transport fell off a cliff as governments told their people to stay at home. A major part of encouraging travellers to use public transport is the provision of systems that allow social distancing of passengers from staff, ideally eliminating the need to exchange physical tickets, cash and paper receipts.
