A survey in the US shows that when looking at methods of payments, cash is still king.
A survey of 1000 people were asked which payment methods they use & responded:
Convenience Stores: 63 % pay cash 41% Debit
Paying someone back: 78% pay cash 18% pay by cheque
57% of Millenials use a greater variety of payment methods than before. Nearly 1/2 of that group said they are more likely to pay with cash now than they did a few years ago.
