Check-Mates is a new anti-fraud technology for eBay and Craigslist shoppers. Check-Mates verifies the real identity of both buyer and seller while allowing them to remain anonymous. Should any fraud occur, Check-Mates logs are released to law enforcement authorities.

Check-Mates' validation process starts by having users type in their real names, addresses and phone numbers. From this information, a set of "non-invasive life experience questions" are randomly generated. If both users answer all of them correctly, they receive an email stating that both identities were confirmed and logs will be kept for future reference.

A company called GenMobi Technologies launched the Check-Mates service. CEO Michael Schultz said. "While fraudsters can steal your credit card and social security numbers, they are hard pressed to know about your personal life details."

Check-Mates charges a $2.95 fee to the initiator of the verification. Check-Mates is completed in a few minutes and does not require any software download.
