But that does not mean frauds exploit it easily.
Any one who has access to the credit card already has the credit card numbers and the security code. One could always use that information and order items online. But there are security mechanisms that protect such usage. The audio recording is identical to storing the credit card number. Square uses other mechanisms (like capturing location of each transaction) to deter fraud behavior.
