2.2 NFC Function - Mobile Scans

NFC (Near Field Communication) is a short-range wireless communication technology that allows devices to exchange data when they are close to each other, typically within a range of about 4 cm. Here's how it works:

Basic Principles:

Short-range communication: NFC devices, such as smartphones, card readers, or NFC tags, must be very close to each other to initiate data exchange.
Frequency: NFC operates at 13.56 MHz, a frequency that allows for fast and secure information exchange over short distances.
Active and Passive Modes:
- In active mode, both devices generate an electromagnetic field to transmit data.
- In passive mode, only one device generates the electromagnetic field (e.g., a smartphone), while the other device (e.g., an NFC tag) uses it to power itself and respond.

To activate and use this feature, a few configuration steps are required. First, from vtenext's administration panel, go to SETTINGS > MODULE MANAGER > COMPANIES (or another relevant module), and add a related field to the Mobile Scans module.

This field will be immediately available on the Wilson App, and by clicking on it, the screen to scan the NFC tag with the mobile phone will be activated.

The tag is captured, and a record is also written in the related field that was previously created

Here is the record as it appears in the related field after being scanned

Note: The NFC function is also available in the Processes module, allowing a process to be initiated from a scan.
