How to Use the Android Beam Option on the Nexus 7 Tablet
The Nexus 7 tablet features an NFC radio, where NFC stands for Near Field Communications. NFC allows your tablet to communicate with other NFC devices, which allows for the quick transfer of information. The technology is called Android Beam.
How to turn on Near Field Communications for your Nexus 7 tablet
The NFC radio should already be activated for your Nexus 7. If not, or to confirm, follow these steps:
At the Home screen, touch the All Apps icon.
Touch the Settings icon to open the Settings app.
Touch the More command found beneath the Wireless & Networks heading.
Ensure that a blue check mark appears by the NFC item.
If it doesn’t, touch the box to add a blue check mark.
With NFC activated, you can use your tablet to communicate with other NFC devices. They include other tablets and smartphones, as well as payment systems for various merchants.
To disable NFC, repeat these steps, but in Step 4 remove the blue check mark.
How to use Android Beam on your Nexus 7 tablet
The way your Nexus 7 puts NFC communications to work is through the Android Beam feature. It works when you simply touch your tablet to another NFC device, such as another Nexus 7 or a smartphone, like the Samsung Galaxy Note.
When the two Android Beam devices touch — usually back-to-back — you see a prompt appear on the screen: Touch to Beam. Touch the screen, and the item you’re viewing is immediately sent to the other device. That’s pretty much it.
Both devices present the Touch to Beam prompt when they get close. If the other person touches his screen at the same time you do, information is swapped between the devices.
On the Nexus 7, you can use Android Beam to swap contacts, web pages, map locations, pictures, and lots of other things. Generally speaking, if the app features the Share button, you can probably use Android Beam.
The NFC field on the Nexus 7 is found on the back of the device, right where the word nexus appears.
