Does the use of cash have an expiration date?

The evidence that physical loot is available at borrowed time is slowly but surely increasing. But do not read the last rituals for cash.

If anything, the box office outlays in the Target stores over the weekend reminded that pay machines are not child's play and when it comes to technology, nothing beats cash failure.

In that sense, you might want to have a modest supply at hand.

Still, you've made it quite comfortable to leave most bills and coins behind. In fact, more of you place your smartphone or smartwatch near the cash register to pay for this or that money with services like Apple Pay or Google Pay. Your wallet and all the money you keep in it will remain in your pocket.

You're as cool as your friends who pay debts and exchange digital money through Venmo, PayPal, or Cell.

You may even wonder where you could someday carry around cash, as the Costanza physical wallet is long forgotten.

Sixty-eight percent of surveyed smartphone owners surveyed by SurveyMonkey Audience on behalf of USA TODAY recently announced that smartphones may fully replace wallet needs. Almost half (45%) believe that wallets are outdated in five years or less.

How much cash should you keep for an emergency?

The Target episode proved that you should not count cash. Some target buyers reported on Sunday that the stores could accept cash (or checks) but could not process their credit cards, even though this hook was much smaller than with much larger outages that target registries ruled out the day before, making payments over Plastic prevented, and yes cash too.

"I think (the target episode) is a slip-up that everyone will quickly forget," says Greg McBride, financial analyst at "However, it is a reminder to all of us that we only have to have a certain amount of cash for the individual case", such as after a hurricane, when the power supply fails.
