Definition of NFC (Near Field Communication): A short-range wireless technology that allows two devices to exchange data when held close together. In MDM, NFC can be used to provision and enroll Android devices by tapping them against a programmed NFC tag or another device.

NFC (Near Field Communication) is a short-range wireless technology that allows two devices or a device and a tag to exchange data when held close together (typically within 4 inches). In MDM, NFC is used to provision and enroll Android devices by tapping them against a programmed NFC tag or another device.

NFC Provisioning

During device setup, users can tap a managed device against an NFC tag that contains enrollment credentials. This automatically initiates device enrollment without requiring manual entry of enrollment information. NFC provisioning is faster and less error-prone than QR code enrollment.

NFC Enrollment Workflow

Device manufacturer pre-loads NFC support, 2) IT admin programs NFC tag with enrollment information, 3) New device is powered on and user taps against NFC tag, 4) Device reads credentials and begins enrollment.

Device Requirements

NFC provisioning requires devices to have NFC hardware capability. Most modern enterprise Android devices include NFC, though some older or specialized devices may not. Organizations should verify NFC support when selecting devices.

Tag Reusability

A single NFC tag can be used to enroll multiple devices. Organizations can create a master NFC tag and use it repeatedly across their deployment. Tags can be updated if enrollment parameters change.

Physical Deployment

NFC tags can be placed at help desks or setup stations where users access them during device provisioning. For distributed organizations, multiple NFC tags can be distributed to different locations.

Advantages vs QR Code

NFC enrollment is faster than QR code enrollment because users don’t need to align a camera. NFC works in lower-light conditions where QR codes might not scan reliably. However, NFC requires compatible hardware on both the tag and device.

Security Considerations

NFC communication is encrypted, but tags can be read wirelessly if an attacker has compatible NFC equipment. Organizations should consider securing physical NFC tags to prevent unauthorized enrollment attempts.
