SYSTEMS AND METHODS FOR MANAGING MULTIPLE ACCOUNTS ON A RF TRANSACTION INSTRUMENT

摘要

Systems and methods are configured to manage data sets associated with a transaction instrument. For example, a method is provided for facilitating the management of distinct data sets on a transaction instrument that are provided by distinct 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 financial transaction instrument, wherein the first data set is owned by a first owner; adding, by the read/write device, a second data set to the financial transaction instrument, wherein the second data set is owned by a second owner; and storing the first data set and the second data set on the financial transaction instrument in accordance with an owner defined format. The first and second data sets may each be stored as a Block of Binary. Furthermore, the first data set may be updated and/or deleted from the financial transaction instrument by the data owner or the transaction instrument user, in real-time or substantially real-time or at a later date. In another example, a financial transaction instrument comprises a data set management system for facilitating the management of more than one data set, the transaction instrument comprising at least one data storage area configured to store a first data set of a first format and a second data set of a second format different than the first format. The first and second data sets are associated with first and second owners, respectively, and are configured to be stored independent of each other. In yet another example, the data sets may be stored on a remote database under the identical arrangement as is stored on the transaction instrument.
