Hey all,
We will be traveling with our adult daughter in April. She has cognitive disabilities. When we ride the Tube will she need her own contactless card to tap in and out? Is there a way to put all 3 of us on one card? Thanks.
No. Everyone needs their own form of payment but they can be on the same account.
If you will be traveling by train around the UK, you may want to consider getting a disabled person railcard for her. It provides 1/3 off train fares for the card owner and one companion. You can register this to an Oyster Card and receive discounts on the tube as well.
It really depends on how much travel you do on whether this is worth it for you or not.
Most tube stations have a wider turnstile for those with luggage etc. Use that entry, it will give you more time to get you all tapped in. Most of the larger stations have staff that are standing next to that entry. I've found them to be very nice and very helpful to tourists.
the Disabled Railcard costs £20 with proof, and does give the discount mentioned by Carol now retired. Unfortunately only the cardholder benefits from the discount on the Tube, not a companion (unless you buy an all-zones Travelcard which may well be much more than you need). You'll need her to spend £60 on tickets to be ahead, plus the £7 nonrefundable for the Oyster. That's quite a lot of tube travel.
Staff on the Tube are prepared for all sorts of disabilities and may encourage one of you to take he through the big gate while the other of you meets her on the other side by going through a normal gate. While each person needs their own payment method one of you can hold her payment method and tap her in and out and then switch cards and tap yourself in and out. That's what I do for my disabled wife. Don't let people rush you.
