Since she's picking folks up, she'd need mobile processing. While you can do that, I did for a little while, it's more costly because of mobile terminal fees and costly mobile service fees. Did it for a little while but I quit. Not a lot of interest. So, I went back to cash or checks. Checks still are by far the most popular. Btw, I did debit cards too with that machine. Lol, I use credit and debit cards all the time. Guess my customers don't lol. Maybe all of her's do, I don't know.
