If the technology that Walmart is backing only requires a software update to existing phones then it is not nearly as secure as apple pay.
A lot of people are comparing Google wallet and apple pay like they are the same thing - they are not. A phone with compromised firmware could leak sensitive data with Google wallet but not with Apple pay.
- drdaeman 12y agoDepends on implementation. NFC has that "secure element" thingy, that is, a TPM, like a SIM card. Implementations may vary. I'm unaware on actual Google Wallet NFC implementation, but I heard rumors (which are not certain by any means) at least Samsung had some hardware-assisted keystore. And I doubt Visa or MasterCard would permit Android vendors to do things on a phone's base OS a manner that could be exploited with a software hack.
- abritishguy 12y agoThe card details were stored on the secure element but the pin was not and because the authentication is not done using the secure element it is trivial to bypass: http://cybersecurity.mit.edu/2012/10/google-wallet-overview-threats-and-security-measures/ http://cybersecurity.mit.edu/2012/10/google-wallet-overview-... The current implementation of Google wallet stores your card details in a google server which protects against these attacks but is not a viable business model (google are making a loss on every transaction since they pay it and then bill the customer themselves).
