No, they won't check ID to see if the names match when entering the festival. The only time they will check ID is if something is wrong is the wristband (not working, lost, stolen, damaged, etc.) BUT the only person that they will be able to help in that scenario is the original purchases (the name its registered under is irrelevant.) So if you're planning on buying from someone make sure you don't pay cash! Only use paypal or some other secure site. That way if anything goes wrong you'll get your money back.
