When a GS1-128 data structure is encoded in a QR symbol, the gs1-128a: eliminates the need for FNC1. The tag itself identifies the data carrier as GS1-128. In a similar manner, the use of QR eliminates the need for the Code 128 start and stop bars, and the mod 103 check digit.

The data is the data.
