A company doesn’t have to be the one directly charging your credit card to play a role in an alleged billing scam. The Federal Trade Commission announced a proposed $12 million settlement with payment processor Humboldt Merchant Services after accusing the company of knowingly facilitating payment processing for fraudulent businesses. The FTC alleges Humboldt processed transactions for more than 1,000 merchants that were actually shell entities used as fronts or pass-throughs for businesses engaged in unauthorized billing schemes. If approved by a federal judge, the settlement would also permanently prevent Humboldt from processing payments for several categories of merchants considered particularly vulnerable to fraud.
