You can do all of that with Adyen, however if you run a shop which people only buy from once in a while, e.g. garden sheds, then you would not have value in the token, therefore this is not a common feature. Adyen works with your shop no matter how PCI compliant and well-built, so you can have it in the checkout or the separate payment page. Interestingly you can also pay by paypal via Adyen. I have found the online login bit for merchants to be as flaky and naff on Adyen as other payment gateways of yesteryear - forever timing you out and not letting you in, just really bad UX as banks seem to prefer. I don't see these blockchain based payment systems as fundamentally solving anything in online payments needed for ecommerce, the Adyen tool kit is pretty large and bits such as the 'token' are not needed in real life, or some of the stranger mobile payment solutions that also promise to change the world as much as the crypto-coin 'promises'.
