I'm still interested to see how any changes to entry to the stadium is managed when we can go back as supporters. I for one, share a SC in the SS (Not in my name) and with potential track & trace implementation i'm not even sure if i'm going to be able to use the card. Must be a potential issue for almost every club and it's supporters.
There is many in your boat who share tickets or sell the odd one on via buy and sells. I think if the comments from city are anything to go by from Autumn time there will be IDs check to verify who is in the ground incase they need to contact people who sit near you.
