The real WTF in this scenario is why does the POS software have access to credit card numbers? A one-way transaction will have all credit card information go directly through the PINpad, without ever being exposed to the controlling PC.
Even then, you've still got weak links in the chain.
Because banks charge per terminal, a lot of smaller chains/franchises use a generic terminals some software sitting on a PC out back so they can have multiple physical terminals presented to the customer but only one software terminal presented to the bank.
PC EFTPOS is one of the more popular ones I've seen in Australia and it is not unusual to see it sitting on the same PC that staff use to check their personal mail and cat videos.
Having installed and serviced POS terminal I've been convinced that cash is orders of magnitude safer despite the risks of losing it or getting mugged (TBH, if you're that clumsy that you'll lose cash, you'll lose your card just as easily).
