I purchased 2 tickets for the Liverpool Luton game and this is what I now know now. I have attached photos showing all this.
Once purchased screenshots of the tickets are sent. I purchased 2 KOP end and got sent 2 Anfield Rd. At the gate the screenshots wouldn't work. The staff explained screenshots don't work and that I would need a link allowing me to download the tickets into my phone wallet. LFC use NFC, near field communication. Same as paying contact in shop with phone.
Here is your problem. The seller will not want to send link as once the tickets are in your wallet you own that ticket, as most of the tickets being sold are from matches of a season ticket holder. Once its in your wallet they have no access to it.
My seller after some back and for didn't send me the link and we got in. Once the Luton game was over the ticket in my wallet updated to the next LFC game. I could have kept them and attended the rest of LFC home games.
You can see the download in my wallet has the small contactless symbol at the top and says show code at bottom. Seller hits show code and screenshots it and that is what I was sent after purchase. You will also notice they are different parts of the ground. I have included some text with seller which took place at the ground
See all my attachments. You will not get into anfield with a screenshot of a ticket! Period!
