Once you choose a phone to download your ticket onto, it will stay on that device, and the next game ticket will automatically appear shortly after the current game ends. That works OK.
You can't easily transfer tickets to other people from your wallet (at least, not on an iphone) but it is possible if you set them up as a 'friend' on the LCFC website and then use the website to forward the ticket on to them (they don't need to be a member, but they do need to provide their DOB, address, email and phone number). They will get a sent a link that will download the ticket you have shared with them onto their own phone (and it reverts back to you once they have used it). You can only do this five times a season.
If it sounds like a ball ache, that's because it is. And if you are in the family stand, you basically have to ring them to do anything.
