Abstract: A method of auction is disclosed. The method includes: detecting one or more auction prices from a plurality of second calculating devices within a pre-set time by a first calculating device; upon detection of at least one auction price, determining one of the plurality of second calculating devices as a successful bidder within the pre-set time; and repeating the foregoing steps until the item is sold or passed, wherein when the item is sold, the method further includes: giving a commission or a red envelope to each second calculating device that has been determined as a successful bidder within a corresponding pre-set time except the second calculating device to which the item is sold. The method enables a user to implement online item transaction through a second calculating device, thus lowering the threshold for a common user to participate in auction.
