Unless the two elements are connected and can decide between

having an Oyster and a PayWave in the same wallet, which already
causes trouble. My wallet, with Oyster, ITSO and a Spanish one (not
sure what standard that one is) is guaranteed to fail!

Yet mine, with an Oyster and two Paywaves, works fine.

Is it feasible to make it choose an Oyster over other cards also present?
It will be a definite hassle compared with what went before not just to be
able to whack your wallet on the barrier.

A market for tin foil wallets outside that of the paranoid?
