I received a call on my business line from a man, thankfully no accent, who said he was working for a company I didn't catch. This company was trying to get their name out there. He claimed they sell those card readers for smart phones and ipads. Having neither was not enough to deter him. I cut off his spiel by saying I don't like conducting business this way and hung up.
This is a reputable company, I checked Ceres National and theyre a company that works doing the transactions you make by swiping your debt or credit card.
