A RF transaction device is provided, which is operable to store multiple distinct data sets owned by unrelated data set owners, wherein the distinct data sets may include differing formats. The method includes the steps of: adding, by a read/write, a first data set to the RF transaction device, wherein the first data set is owned by a first owner; adding, by the read/write device, a second data set to the RF transaction device, wherein the second data set is owned by a second owner; and storing the first data set and the second data set on the RF transaction device in accordance with an owner defined format. The first and second data sets may each be stored as a Block of Binary. The first and second data sets are associated with first and second owners, respectively, and are configured to be stored independent of each other and in accordance with the particular data set storage protocol.
