Afaik there are none, but I don’t really get why I should use these services anyway. Pulling out my phone is only marginally faster than just using a card directly. They do improve security, kinda like a real life PayPal they prevent others from getting your card on file, but it’s not worth the cost in privacy imo. That’s part of the reason I use a credit card in the first place: Credit companies act as a proxy between you and your bank account and they offer some fraud protection.
