RFID Labeling and Verification System
Business Needs
DiaSorin, a global provider of clinical medical devices, has a system called the LIAISON. The LIAISON machines analyze samples by utilizing reagents; these reagents are contained within a disposable product known as the Reagent Integral. In the past, these integrals were identified by a label containing 15 barcodes that was manually placed on the plastic integral. As the LIAISON machines evolved, they required an RFID tag in addition to the barcode label to identify additional information regarding the reagents.
The overall project goal was to produce an automated process for printing bar code labels, writing RFID tags and to verify the correctness of operations executed during the assembling process. Integrals whose information did not match with those expected are isolated to be rejected and/or reprocessed.
