Doesn't concern me at all
We need NFC why again?
Google has started provisioning electronic wallets again having fixed the more trivial security flaw in its product - though determined hackers will still get in. Google suspended the supply of Wallets after it emerged that simply clearing the application data resulted in the protecting PIN being reset, so now anyone trying to …
Or... just maybe, they bought them over the phone or online! A sophisticated criminal?
Also the PIN isn't your bank card PIN it is just a pseudo security lever which is a lot more than your normal wallet has - which is the point. We're talking about bonk cards not bank cards - same on the phone.
You do bonking with you wallet completely unprotected, you bonk with you phone with protection but not very good protection.
I think he was referring to a physical wallet.
IIRC, the Google Wallet still has the maximum transaction and maximum wallet load limits, so it's the same as carrying (say) £200 around.
Presumably, being an electronic (and trackable) process supported by various banks, you're also covered in the case of it being stolen and used.
Also, why would they need to brute-force your credit card? Plenty of places still take signature (and don't check) or support "card-holder not present" transactions where the CCV and address (which is probably also in your wallet) is considered a security check.
I doubt I'll use Google Wallet myself, but it doesn't strike me as being any less secure than the alternatives.
