Got a pair of concert tickets you wanna show off? Yeah we've all done it. Taken a picture of a pair of concert of sporting event tickets & posted the pic on Facebook or Twitter. Well nowadays someone could use your tickets without even physically taking them from you. Online thieves are now using the barcodes from photos of tickets posted on social media. So as tempting as it is, don’t post pictures of tickets with barcodes on Twitter and Facebook or you run the risk of losing those tickets.
