Is it a move forward or backward with respect to avoiding double spending?

It's a move to disaster. Just another attempt to get rid of cash.

I tried to read the article, though it does not share so much details about how this is going to work. Are they going to use some other protocol like USSD codes, otherwise how is the money going to be deducted from the buyers account into the merchants account for example when performing a transaction/trade?
Some please help explain how this will work?
