Abstract
A method, system, and apparatus for sending data from a base station to an RF tag, whereby the RF tag comprises an 'intention to write to memory' field, and the 'intention to write to memory' field is written before writing the data and cleared after the data is successfully written. If the data transmission is interrupted and partial data is written to the tag, the 'intention to write to memory' field will not have been cleared when the tag is checked at a later time through interrogation by a base station.
