NFCTagTechnology_MifareClassic API

Subset of NFCTagTechnology. For code examples, see Rhodes System API Samples: NFC.

As of Rhodes version 3.3.3, the Barcode, NFC, and Signature Capture APIs, as well as Rhom data encryption are removed from Rhodes. These features are only supported in Zebra RhoMobile Suite. If you wish to use these features, you will need to upgrade to RhoMobile Suite. Your application’s build.yml will also need to be modified to indicate the application type is ‘Rhoelements’. Additionally, a RhoElements license is required.

Enabling NFC

To use the NFC methods, you need to enable NFC on the Android device and ensure that the version is 2.3.3 or later. Do this by adding that capability to the build.yml file:

android: 
  version 2.3.3
  extensions:
  - nfc
