OK, tried to get the "ICE Travellers Cashcard", as quoted as best bet by MSE (apparently no charges at all if you get one in Euros, which Ryanair use). Complete waste of time. Registered on the web site. Click on link to order a card, takes you to a screen that insists you have to put in Driving Licence or Passport details. Get the passport out the safe, put the details in, click on the link again, get back to same screen again wanting D/L or passport details.
Sod them. 2@s
