I mean, since the last time I’ve visited: it seems like no one ever carries it. I prefer it because CC charge additional fees (which end up making the item cost more) I have a small rant about that: STOP RIPPING OFF PEOPLE WITH THOSE SURCHARGES?! (It should be 0 rather than 1%) as it may seem trivial, they add up overtime. Are stores allowed to refuse cash payments outright despite them being legal tender?
Okay, though if this created a resurgence in the cash economy, I think the government would amend the legislation. A lot of companies might not want to deal with the cost/ risk of handling more cash.
Mostly I expect that the highest card surcharge will become the new price and if there is a cash price, it will just be the current price at best. It really looks like it will just mean higher prices for all consumers and less versatility - the biggest rent payment platform owned by Macquarie bank has already stated they just won’t accept cards any more.
