May I ask how you think a railcard becomes faded? It's not something which needs to go through barriers or even needs to removed from the ticket wallet. If you will insist on shoving other tickets over it/taking it out of the wallet daily, putting it in the washing machine or otherwise maltreating it then it will get damaged.
I bought a Southeastern Network Railcard back in March. I purchased it not because I use it mega-frequently, but because I go to London maybe 6 times a year, and it saves me quite a bit of money, even using it that infrequently.
Between March and August I'd used it about three times; three separate weekends where I'd gone to London, and it had been in my pocket, in its wallet, for the duration that I was using it, and apart from that, it remained on the mantelpiece in my bedroom. By August, it had faded so badly the date was so poorly legible so I felt compelled to buy a new one.
So in my case there was no maltreatment whatsoever.
With a similar level of use, my new one seems to be faring a lot better. I'm at a loss to explain that!!
