In what von Behren categorized as an unplanned move, he has left Google entirely for Square’s San Francisco office. von Behren told the NFC Times:
“When I left the Google Wallet project in January, I fully expected to stop working in payments but to remain at Google,” he said. “After meeting the team at Square, however, I decided to do the opposite. Square is doing some great things in the payment space. They have a strong leadership team and a culture that fosters innovation.”
Square’s current solution doesn’t rely on NFC. They manufacture a dongle that connects to your Android smartphone or iPhone and allows small businesses to purchase credit card transactions by swiping a card through the dongle.
Square has just re-released their consumer app which is now called “Pay with Square”. This payment method allows people to pay without submitting a card for swiping.
The app uses geolocation to identify account holders in proximity. This would be a really good place to start looking for NFC integration.
