How can auctioneers verify the identity of bidders?

Requesting identification before the auction starts is a method that ensures the auctioneer can confirm the identity of bidders in a reliable and secure manner. This procedure typically involves asking for a government-issued ID, such as a driver's license or passport, which contains a photo along with verification of the person’s name and other personal details. This process not only helps in preventing potential fraud but also establishes a formal record of who is participating in the auction.

While taking photographs of bidders could be a way to identify them later, it does not provide an immediate verification like identification can. Checking social media profiles is not a standard or reliable way to confirm identity, and simply asking attendees their names lacks the verification necessary to ensure that the person is who they claim to be. Thus, requesting identification is the most effective and commonly accepted practice for verifying bidders’ identities in an auction setting.
