The Nexus 4 and 10 were the first in the product line to display Google's switch to Broadcom chips after their launch in late 2012. As was the case with the 4 and 10, the 2013 Nexus 7 will not be able to write to or read from the popular Mifare Classic class of NFC tags.
Despite this, the new Nexus 7 in fact features a slightly different Broadcom NFC controller assembly, which lacks the STMicroelectronics embedded secure element that is found in the rest of Google's current Nexus handhelds; the Nexus 4 and 10 contain Broadcom's BCM20793S controller, while the 2013 Nexus 7 contains a Broadcom BCM20793M NFC controller. This means that the device is physically incapable of using Google Wallet in the service's current form.
