Amazon Cash - how should this work?

While the trend in society and in all industries seems to be that cash is playing an increasingly insignificant role, Amazon seems to be interested in a further existence of paper money. At the very least, they have adjusted their service to the fact that there are still customers who do not want to use the various digital payment service providers on the Internet, make direct debits or apply for credit cards. Still it hooks the so-called Amazon Cash but above all in the number of contractors and the overview of the branches.
