UDI label and lot or expiry code verification
A UDI appears on the label in two forms, plain text and a machine-readable code such as a barcode. The device identifier is the fixed part; the production identifier carries the lot, serial number, expiry date or manufacture date (FDA, UDI Basics).
The station reads the barcode, reads the printed text with deep learning OCR, and checks that the two agree and match the job. Deep learning OCR outperforms rule-based methods on degraded or low-contrast codes and needs no per-code training. Round parts such as syringes, tubes and vials are read in any orientation, and inner and outer labels can be paired to the same unit.
