- Both Nearby Share and Near-Field Communication allow one to share links, videos and Photos.
- How tags are used on NFC.
- Security details on both Nearby Share and Near-field Communication.
Earlier we covered Google Nearby share’s new update, that it now allows users to share applications and new updates and as a follow up to that we find it prudent to give a detailed comparison between Google Nearby Share and Near-Field-Communication (NFC).
Google Play Nearby sharing feature is a convenient model to share links, files, videos, photos, application and more, However, one can also find Near Field Communication (NFC) as much similar to Google Play Nearby sharing but they’re technically two different features. NFC is also quite handy for transferring data between two devices. It also allows one to send photos, videos, files or to make a payment. One needs to be able to distinguish between these two features because some of the functions are similar. These two features contain features as well as differences.
The two features operate differently, For instance, Near-field Communication enables short-range communication (4 cm Distance), between compatible devices. The process requires at least one transmitting device, and another to receive the signals. Passive NFC devices include tags, and other small transmitters, that can send information to other NFC devices without the need for a power source of their own. Whereas, with Google Nearby Sharing one can choose from the devices within one’s proximity which means Nearby Share allows the users to interact from a distance. Google Nearby Share use the following protocols for fast and easy sharing, Bluetooth, Bluetooth low Energy, WebRTC or Peer-to-Peer Wi-Fi. Nevertheless, one can notice that these two features can also operate whilst one is offline.
Also, there is a peculiar characteristic that is only within Near-Field Communication which is the NFC tag. It is an unpowered NFC chip, small enough to be embedded in items such as posters, movie passes, business cards, medication bottles, stickers, wristbands, key fobs, pens, hang tags, and more. NFC tag is passive, meaning it won’t have any power source. Instead, it draws power from the device that reads it. The microchip can store small chunks of data, which can be read by NFC-capable devices.
Moreover, there are specific Android versions and categories of smartphones that support these features, Google Nearby Sharing is found in phones that have Android version 6.0+. In the same line, NFC is available on more or less every high-end out there, but it is not available on all mid-range and entry-level handsets.
Furthermore, these two Features there are secure. NFC is based on contactless smartcard technology, allows secure data exchange by using encryption and a special processor. In the same line, wireless technology limits communication to within a short distance, reducing the opportunities for an attacker to eavesdrop on communication. Google Nearby Share was built with privacy at its core so that one can share and receive files with the peace of mind. Nearby share allows one to adjust privacy settings from the phone’s Quick settings at any time.
Nearby Share was recently updated, now one can share Apps and app updates, for more information on this update, one can check the previous article on this website. On the other hand, sharing apps via NFC does not share the app’s APK. Instead, the sender’s device just beams the app’s Play Store page, and the receiver device opens it, ready for download.
