Retailers aren't on the hook for CC fraud, the issuing bank is. At least that is how it works with my banks.
This is true, however if chargebacks occur beyond a certain threshold, CC issuers will raise transaction rates as well as impose extra fees. On the flipside, I'm sure chargebacks aren't too big a deal for large merchants.
With major retailers getting information stolen, I don't see mobile payments being too far off from being a thing of the norm. Cards and pin codes just aren't enough anymore.
I think this will be one of the primary drivers behind apple pay. All the other mobile payment platforms (Google wallet, Paypal, Isis...etc), store payment information on their servers. Whereas apple pay does not, it uses a token for all transactions.
For whatever reason, google doesn't like to advertise. I have seen 1 advert in the last year from google and that was for the Chromecast. I wish they would advertise more.
I like this...you would think a company whose primary revenue comes from advertising would advertise. But the way I see it, google wallet isn't super profitable so I doubt they care if people use it. They already read all our emails so they know what we are buying. As far as data mining goes, not sure how much benefit would be added with google wallet.
As far as entering the digital payments business. It is a weird move from apple, because again, it isn't super profitable. They have something bigger up their sleeve, no idea what it is though.
