Seeking ideas: how to use bank card to swipe consumption?
Do I need to have a data interface with the bank?
Has any of my dears already done this?
I am willing to pay for the original code, and the price is negotiable.
I know how to achieve it, but it ’s not something you can do
Of course, there must be a data interface, otherwise how do you know if there is money on the account?
ATM / POS is deployed by banks or UnionPay, but it is not just a POS that can be used
