Anyone use one of these?

Got me thinking... I've seen some larger camera shops on ebay that state they DO NOT accept payment via Paypal, only through credit cards(I'm assuming you call them and do it over the phone?)... Well anyhow, I've noticed some coffee shops here in LA that are using them now, and seem to be loved by customers and the business owners, simply because they only charge a per-transaction fee, no daily fee, no monthly fee, etc...

So... what's the deal? Anyone heard anything other than some scumbags who've used them to "skim" credit cards, I'm just looking at this as an option if I continue to sell @ the local monthly camera show(since ya'll are tight wads it seems lately ).... No matter.

thoughts or advice on these? This would be only used as a secondary option to cash transactions for in-person deals...

thanks,

Dan
