How does this work on Google Wallet? Is the card on the lock screen as well? Is it verified with a passcode? Do you need to sign or transact with the credit card terminal in any way?
There are zillions of Google Wallet demonstration videos online, if you're interested. Not surprisingly, most were also filmed at McDonalds
Payments are almost exactly the same, except that you can either set it to require a PIN each time, or you can do it once and set a long timeout before it's needed again. (If your phone is lost or stolen, just go online and suspend Wallet. Same as with Apple Pay.)
And this is why I would not want to use Google Wallet even if I had an Android phone. I'm trying to cut Google's influence OUT of my life, not give them more access.
Six of one, half dozen of the other.
With Google Wallet, Google might use the purchase info to help with Now cards or targeted ads. In return, we get various services. Everyone knows this.
However, most purchases are hidden from the credit card companies, as Google becomes the merchant of record.

What most people don't know (and Apple sure isn't going to point out) is that:
With Apple Pay, the credit card companies get to continue collecting data on our purchases, which they not only continuously profile to determine our credit worthiness, but it's information which they
likewise sell to ad networks.
Not only that, but in return for using Apple Pay with "more security", we get... well, nothing. Not even a kickback. Instead, the kickback goes to Apple. Not their customers.
In other words, Apple Pay users and their purchases are the product that Apple is selling to the banks.
