The advantage is much more durability. Hardier materials, and the print can lose an entire paper sheet's worth of mass/thickness, and still be readable.
Those properties sound beneficial in non-obvious corner cases.
In particular those when a sheet of paper’s thickness does not impact the required data density.
While storing data on a wear surface is desirable and necessary to system design.
And when conventional use of a engraved number as index to extended data is insufficient.
