I would define this property in a way that it is a compatible with QR Codes. The Wikipedia entry for barcode seems to use such a broader notion.

https://en.wikipedia.org/wiki/Barcode

tentative +1 to @mfhepp - it's a "visual machine-readable code".

On the other hand, if there are really only two subtypes and it is often important to distinguish, maybe we should make them explicit.

Even qr codes are used in many ways - let's avoid a hardcode taxonomy that will date quickly

I updated the definition to "visual machine-readable code such as a barcode or QR code".

Merged for review/discussion. Also note that we have

http://schema.org/ticketToken http://www.w3.org/2000/01/rdf-schema#comment "Reference to an asset (e.g., Barcode, QR code image or PDF) usable for entrance." .

... in the schemas nearby. It seems complementary. We could add Barcode or CreativeWork to the range values for ticketToken but I don't think that is essential.
