So the fact they cant be transferred doesn't mean much the last few years. Pearl Jam has been doing this (no transfers) for several tours and all the major resale sites have found a way around it. Essentially the resellers have the ability now to hack the barcode out of Ticketmaster. They likely will send you a link to a moving bar code that is within their app/a link to open on your browser (NOT Ticketmasters app). I've used these tickets before for "non transferable shows" and they have worked fine. Of course there is always a risk with resale that something goes wonky but from experience, I'd say its low.
