Maybe I've been not enough clear in my message but the cash is the same what I'm proposing is a small device which will cost like a POS ( which is mandatory ) or even 0 ( ZERO) if used by a phone which allow business to accept CASH-payments which at the moment is a very restricted way of paying here in italy ( try to pay with a 200€ bill in italy and tell me ) and which still cause a huge hole in state income and that they are trying to arginate with very creative solution ( now they are proposing a cashbacks on credit card payments, or even a tax on cash withdrawals ) this way would be 100% more effective on cash-tax-evasion and easier to implement ( will be applied only on 10+€ transactions on cash-transaction which anyway the state is already trying to dissuade as much as possible) the qr code on banknotes is optional.. and maybe will come anyway in future.. banknotes are updated every X years anyway...
