Cash is accelerating down the path to extinction as new technologies threaten to mark the end of loose change within a decade.
Bank and credit union bosses say cash won't be alone, with wallets and credit cards also likely to disappear too.
They told The Advertiser's round table forum that cash and cards will be replaced by computer chips embedded in mobile phones, watches or other portable devices.
Australian Central chief executive Peter Evers believes cash will be replaced for most transactions in five-to-seven years.
"Cash will disappear as there will be other forms of carrying cash, stored value in your phone or whatever it might be. It will transfer automatically," he said.
"We're very close in countries around the world. If you go in to Hong Kong or Singapore, the low-value transactions have already disappeared. You can't go anywhere, like on public transport, without pre-purchasing a card.
Dutch Supermarkets Set to Refuse Cash
Dutch supermarkets are hoping to phase out the use of cash by 2014, the Financieele Dagblad reports on Thursday, quoting the retail board CBL.
The aim of the ban on cash is to make supermarkets less vulnerable to armed robberies, the paper says.
According to CBL research, 87% of customers support moves to stimulate the use of direct debit cards.
The Telegraaf reports that €10bn of supermarket total turnover of over €30bn last year was in cash. Supermarkets had to deal with 200 'incidents', ranging from a grab at the cash register to armed robbery, the paper said.
Other solutions will be found for customers who do not want to use direct debit cards, a CBL spokesman said. 'Technology is making enormous advances. Trials are also being done with payment by mobile phone, but you can also pay with a finger print or iris scan,' the spokesman said.
The Dutch consumers association said the move was 'going too far'.
