Its use in the warehouse
The most common application identifiers in the warehouse are (01) for the product GTIN, (10) for the lot, (17) for the expiration date in YYMMDD format and (21) for the serial number. Many food, beverage and pharmaceutical suppliers print them on the case, which allows all of the data to be captured with one scan instead of typing each element.
How Chainlink WMS applies it
In Chainlink WMS, when a GS1-128 label is scanned at receiving, the app records the product, expiration date, lot and serial number if the label carries them. If an element the product requires is missing, the app requests manual entry.
