Call for Artists, Making Money at Juried Art Fairs, Craft Shows and Festivals
I just signed up for intuit gopayment. If sales are under $1200 a month there is no monthly fee. However it does work with a smart phone. I only work about 4 shows a year so this is a great plan for me. Plus the transactions will go to my quickbooks online to be downloaded to my business quickbooks. Which is a great plus for not having to manual entry the sales. Hope this helps.
Another thought is that if your cell phone has web access, or if the event you are doing has electricity and Wifi, you could take a laptop and have paypal available.
Hope this helps some.
Try First National Processing who is a sponsor here. Rather than wireless ask them about one of their store and forward machines. Pretty inexpensive ($150 or so), a good rate, and you simply plug into a phone line at the end of the day and upload your transactions. Challenge with wireless is the monthly connect charge is usually $15-20.
I use ProPay. (Www.propay.com) I have an account that's one step up from the most basic and I pay $69/year for it, but there's no monthly fee. (Of course there are per-transaction charges This level of account allows me to accept Visa, MC, Discover, and American Express, and it's so much easier to say "Yes, I do!" when someone asks about taking those last two cards.
While I could enter the transactions over a phone, I prefer the online entry process. (Use a knuckle-buster to do the sale, then enter the #'s online....which can be tedious.) They do have a little electronic swiper gizmo, and some smartphone versions, too, for an extra cost. A couple of times I've needed to work with them on a couple of issues (went over their processing limit twice) and they graciously and quickly extended exceptions to me--now, that's great customer service.
Check 'em out--they're a good outfit.
I would add that I too use ProPay and I love them! I've used them for 6 years with no problem :)
Good luck at your first trade show!
