Its funny, because while I have noticed a few "legit" eccie ladies that take them, I've noticed most of the girls that have the "accepting credit card" picture on their backpage ad, are the scammers.
Like this fake as bitch ....

Let me tell you how this works:
Once she gets your money, it is very hard to reverse because the way the scam works is ... you swipe your card, the money goes into one account and then her/their pimp (likely while sitting in the parking lot or on your street) transfers that money from the "square card reader account" to a 2ed account not connected to the square card and BAM your money is gone that quick.
This can be done in less then 10 minutes, all while she is sweet talking you to your face and stalling time, once she gets a text from her pimp that the money has been transferred .... she is suddenly not a hooker, you are mistaken, you have offend her and she is out the door, leaving .... with no refund to you.
Now it's on you to fight that $300 hooker charge you just made with your bank ... and let the paper work begin
But pimp daddy just got your money regardless because now that it has been transferred to the 2ed account, it is now untouchable by the "square card reader" company.
