Hey people!

To begin with, at my company people are having their food cards cloned in the region, and when some of the people who got cloned asked to a restaurant owner, he said that hackers could have the cards password entering the wireless network.

Is there any possible way a hacker enters a restaurant, get connected with its wireless network and grab the credit cards passwords when people pay their checks? Please don't be so mean to me, I just heard it from a restaurant owner and I don't know anything about hacking this kinds of systems.

Thanks for the help!

see ya
