If you've ridden in New York taxis for a long time, you're probably already wary of the credit-card machines that have been installed in many of them. The ones that have been in cabs for a couple of years now never really worked, and not handing over cash just feels weird. The Post reveals today that cab drivers are also suspicious of the devices. In fact, many of them would do anything to prevent you from swiping. According to the tabloid, they'd rather just grab your cold, hard cash and will lie about broken machines or fake policies to make sure that's how you pay. The Post doesn't specifically explain why some drivers would rather have you pay them in cash, but the implication that most cabbies are cheats is pretty heavy throughout the piece. The problem is so bad that the head of the Taxi and Limousine Commission himself was once prevented from using a credit card by a deceitful cabbie. The cabbies' union claims that the problem is the equipment, not the drivers. After the jump, some technical advice on what to do to avoid this problem.
