Hi Dave,
Thanks for reminding me about this.
To answer the original query, the 60+ Oyster is internally described as an elderly persons freedom pass. They are apparently not allowed to be added to Oyster online, so the card had been hidden from my account. The nice lady I spoke to has unhidden mine again, but said that it might get hidden again at some point in the future. Anyone else with the same issue can call the helpdesk. You need to speak to the Oyster card section, NOT the photocard section. I was batted between both until I got someone who understood.
Now about expiry dates. Yes, this is a long standing problem. My 60+ Oyster says that it expires before my 66th birthday on Oyster online (6 years after it was issued). On the photocard website it says both the correct date (15 days after my 67th birthday) and the incorrect one under the somewaht superfluous line showing no credit. I’m certain my kids zip cards all had similarly weird dates printed on the card which didn’t match the actual expiry. While potentially confusing, I wouldn’t worry too much about it. The correct date will be encoded on the card itself.
Hope that helps everyone.
