1 million Android NFC devices are being shipped each week

"During yesterday’s keynote, Hugo Barra, the director of Android product management, revealed that Google is now shipping 1 million NFC-enabled Android devices every week. That’s pretty significant.
For some context, the company said that 400 million Android devices have now been activated, with activations currently flying in at a rate of 1 million per day. This means that phones with NFC built in represent nearly 15 percent of all new Android devices."
