Nothing stops them from saving your public token or number or whatever they'll come up with, or even using the current Wero system. My favourite online store can save like twenty different payment system credentials, what's another one.
No more than visa and mastercard currently. You need a bank to create you your one time debit card. With payment system one time debit card is not needed, because your public facing token isn't enough to make a transaction, so there is no problem here. Which also makes it trivial to implement multiple "wallets" inside the account, or multiple public tokens with different "wallets" associated with it.
