I've installed Google Wallet on both my Samsung phone and Samsung watch. How can I control which device is going to be doing the payment? Will I have a problem if I hold the phone to pay and it's in the hand that has the watch on? Is there anything I should be concerned about? I'd like to be certain that the card I want to use from the device I want to use it from will be used and not whatever card is currently chosen on the other device.
You only control the device you choose to pay with, if you wanna pay with your phone, open up the wallet on your phone, if you wanna pay with your Watch, open up the app on your watch and pay with that. They don't contradict each other.
