I'm in the US unfortunately here.

So working in FinTech for decades taught me a lot about how these systems work. To be clear, I'm talking about adding a credit card to your google wallet, not keeping money in your google wallet, so disputes and everything still go through the credit card company. Call me paranoid, but carrying around cards now is a risk, especially when traveling. I carry around one spare in case the phone gets stolen, but it's the card I know I can lock down immediately.

Tokenized payments are the most secure because no data about you or your payment info is transferred at the PoS/terminal/till when you check out. It requests a one time token from google wallet/apple pay/whatever and some metadata about the transaction into the terminal, which passes the token to the banks. The actual passing of private details then happens solely between those two parties, the money is (scheduled) to move, and the bank informs the register that the sale went through.

Credit and debit cards contain your personal info. While the stripe exists on it it can be skimmed and duplicated, and even with the chip someone can still steal it off of you and make bogus purchases. Tokenized payments you are required to be present for it to work. If someone steals your phone they can't access the wallet app without you there, it's low likelihood they could even access the account without you there. Even then, you can erase it remotely now.

So, I don't care that it's Google wallet, some other name would be fine, if there was a more open one I'd use that in a heartbeat, but I am a stickler for tokenized payments. It's just undeniable that they're more secure.
