NO! The barcode scanner, as RudiC quoted, "acts LIKE a keyboard". It has a limited ASCII set and uses the KB event, BUT, have you found out whether it has a separate device in the '/dev/' drawer?

Not sure how you are able to read '/dev/input' as this is a directory on Ubuntu 16.04 64 bit
OS. You must be reading the 'event' which is 'event6' on said OS.

With the barcode scanner NOT plugged in do:-
ls /dev > devlist1.txt
Then plug the barcode scanner in, wait a few seconds and do:-
ls /dev > devlist2.txt
Then find the difference between the two...

If so, you could try the 'xinput' command as xinput list keyboard or something similar, assuming the binaries are in the $PATH and disable the barcode scanner and see if that still produces an output at the event handler. If not see if it can be read from its separate driver that you would have found from above. I am sure it is capable of having a separate driver for other possible uses -- BUT -- I have NOT got one so my help IS limited.

If successful you WILL still need to understand the protocol that comes from the barcode scanner, which sould closely follow a subset of that of the keyboard...
