In order to solve the embarrassing situation that people often have no cash or
change when they want to take the bus. But it's too expensive to take a taxi, so we designed a device

it.And you can be ready before the bus arrives, so that you can take a step faster. A fee of only one dime
is charged for one yuan, of which one fee is charged.30% will be donated directly to Project Hope. It is
not only convenient for oneself but also helpful for others.
