PROCEDURE FOR MANAGING THE ENTIRE PRODUCT LIFECYCLE BY USING RFID TAG

摘要

Invention herewith described refers to the procedure for managing the entire product lifecycle by using RFID tags. From the moment of placing an RFID tag to a product, the process continues with the following steps: accessing RFID tag via wireless computer connections by the user-defined RFID software applications at every stage of product life cycle in order to read the encrypted data already entered with an RFID tag, or entry of encrypted data on the RF tag if there is a change in phase of the product life cycle. The invention relates also to the process of organizing data on the RFID tag with defining more memory sectors where each sector is assigned to a phase of life cycle.. Depending on product type and the phase of life cycle, memory sectors are composed of variable number of two-byte long blocks for storage of encrypted data. Data encryption is executed by user-defined RFID software application according to the conversion scheme of user readable text into encrypted marks of size of four ASCII characters.
