Google teaming up with Citigroup and Mastercard to roll out NFC payment capabilities- involves syncing up the credit card companies apps. will give google access to consumers digital shopping cart information (something that PayPal doesnt get. Google will play a similar role to what PayPal does now- it will be a third party entity)
Send allows instant disbursements - imagine payments from insurance companies that land to your bank account nearly instantly - and P2P payments that let consumers "seamlessly send and receive funds from friends and family typically within seconds through providers including issuers, money transfer operators, merchants and more."
