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
that can solve this problem, so that you don't have to go to the shops to change money and worry about
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.
