4 vendors and 4 cards, and see which processors take the bait?
No, actually, it wsn't anything like that at all.
It would be a way to actually HELP the vendors, by showing them that their processor isn't secure, and they deserve better, as do their customers, and should not be made to look bad.
As for service contracts, if my customers were being ripped off and put at risk by my processor, I think there would be more than a contract at risk.

I'd be telephoning my attorney general, after I called my lawyer.
Business name is very important, and I would not want mine messed with after the blood, sweat and tears it takes to actually build a successful company. Most of the vendors work hard for their $, as do we.
If the vendors are in the dark, somebody needs to hand them a flashlight, that's all.
