Is it right that tickets from ticket master have a bar code on to scan?

I recently got some front row tickets to see Shayne Ward from ticket master, the tickets were emailed to me with a bar code on. I have never booked tickets through ticket master before so I was abit worried when they came through. So if I just print them off and show them when i get to the arena it will be ok? I'm just abit worried because usually I have had actual tickets. Just need some reassurance to guarantee that it is fine.

you'll be fine, don't worry about it! other services like fandango, usps, and ups also allow you to print out labels/tickets with barcodes on them.
