Canadian software company WaudWare Inc. claims its Produce Inventory Control System meets the fifth milestone of the Produce Traceability Initiative.

"We are now able to produce the required bar codes mandated by the Produce Traceability Initiative, which includes the Global Trade Item Number and, if applicable, lot and quantity information," Charles Waud, president of the Brampton, Ontario-based company, said in a release.

To meet the fifth milestone of PTI, a 14-digit GTIN and the lot/batch numbers must be encoded on a barcode on each case of produce. If the lot/batch numbers aren't unique by pack or harvest date, the pack or harvest date must also be included in the barcode.

WaudWare uses a standard barcode called a GS1 128 barcode, capable of being read by all scanners, according to the release. The barcode can hold up to 48 characters of information. The numbers that go inside WaudWare's barcodes are GTIN and the lot/batch numbers.
