Ok but what if I wanted to shop without a smartphone, or don't own one? Don't get me wrong this is great for the current situation but like all things it doesn't only have good things about it.
Yesterday on Spanish local tv show they showed how in a small rural town without banks / ATM's, a pharmacy dubbed as a bank / cash retrieval service in a rural town... In another town the banks shared an office and each day of the week was for one of the banks to recieve customers lol. WeBank Could have the same but backwards, give cash, recieve e-coupon, scan e-coupon in store.
The largest store in every town is usually a "financial correspondent" of one or more banks.
The services available are: Remmitance sending/receiving, deposit and withdrawal using bank card, credit card payments, service payments (Eelctricity, Phone, University), service withdrawal, (Drive sharing driver withdrawals), among others.
The tricky part for banks and businesses is offering services with similar deposit/withdrawal amounts so cash is always available without having to organize cash delivery to/from the bank correspondent.
