Abstract:
1. A method of transacting objects, each object comprising an identifier identifying an object identity, said method comprising the steps of: performing a potential transaction interaction with one of the objects by reading the identifier using a data reader; generating transaction data in the data reader, said transaction data identifying the object identity; sending the transaction data from the data reader to a computer system, thereby enabling the computer system to identify a transaction history for the object identity and determine whether the object identity has been transacted in a previous interaction; and if the object identity has been previously transacted: otherwise if the object identity has not been previously transacted: wherein the transaction history data identifies when at least one previous transaction of the object identity was made, said transaction history data enabling a user to conclude whether the object is second-hand or the identifier is a duplicate.
