This is basically offloading the record keeping to the bank. However, in an environment where the cash transaction is king, using this method has little value.
I live in Germany and cash is still the preferred here. My small town near Cologne only started to adopt credit card about 6 years ago. When we arrive, the only shop that would take credit card was the petrol stations franchises.
Wow. Here in New Zealand we switched over to EFTPOS ( debit cards ) around 20 years ago. I was still in school when cash was becoming rare. Mid 30s now so cash seems odd to me.
