Method for preventing an unauthorized use of disposable bioprocess components
View Patent ↗This invention provides a system and apparatus that is able to authenticate and prevent illegal manufacturing and unauthorized operation of disposable bioprocess components. This invention utilizes a ferro-electric random access memory chip (FRAM) chip to store error-correctable information on a RFID tag attached to the disposable bioprocess components, where the error-correctable information is written in sequence into the memory chip, so that the redundant information can remain in the chip when the RFID tag and disposable bioprocess component is gamma-sterilized. Also, this invention includes a method for authenticating the disposable bioprocess component that reduces liability in that a counterfeit poor quality disposable component is not used on the hardware so the user will not file an unjustified complaint.
