To encourage the use of mobile payment for fees for on-street parking to further reduce the service charge of convenience store chains, TBKC started the second campaign in 2019H2, continued the 10% discount policy in 2020H1, and introduced the 15% OFF policy in 2020H2. In the accompaniment of publicity materials, TBKC successfully boosted the mobile payment rate of parking fees from 1% to 16.97% by the end of 2021 and reduced the convenience store rate from 85% to 58.34%. Based on the rise and fall of the utilization rate, it is estimated that the overall service charge for collection in 2020 will be about NT$10 million less than in 2019.
