Plaid, I think it is a new service. But I think well worth it. I am selling my nap blankets at my son's daycare and am accepting checks from them. So I will be testing this feature very soon.
I think there are even some free apps for scanning/swiping credit cards as well, I haven't looked into them much yet as I'm not sure the craft fair scene will work for my products, but if you're making that venture it's worth looking up.
