This also works for Google Wallet, you could change the messaging around it to indicate that.
Because I don't see the.... utility if it?
Unless this achieves something specific I don't know.
So yeah, in Google Wallet you can just add the loyalty card like that (scan the qr/bat ode or type the number), and then have it synchronised to your account (to have it available on your other phone for example).
Sure, not every kind of the pass can be added like this (not movie tickets or boarding passes), but all that matters.
