Seoul s latest transport policy of removing fare collection boxes and expanding cashless payment methods on a quarter of the city s buses has faced a backlash as people without access to electronic banking services and the elderly are feared to fall victim to the automated fare collection system. Starting in March, 1,876 city buses on 108 routes, or 25 percent of the total, only allow passengers to pay by card or app following a five-month trial run on 171 buses serving eight routes.
