Ticket Exchange All tickets for Solfest 2008 will be electronically barcoded. If you can't attend and want to sell your ticket on, you must register the new owner's details with Tixmob. If someone tries to sell you a barcode but does not agree to transfer of details, they are most probably a tout selling you a dud which they have already sold to loads of other people. Once the barcode has been swiped once, no one else will be able to get in with the same code. Caveat emptor!
