1. Log in to the Kuika platform.
2. Click on the New App button to create a new mobile application via the Apps screen.
3. Enter a name for the app.
4. Select Mobile compatible app and then click the CREATE button in the bottom right corner.

1. Creating a Mobile Application

• Log in to the Kuika platform.
• Click on the New App button on the Apps screen.
• Give the app a name.
• Select the Mobile compatible app option.
• Click the CREATE button in the lower right corner.

2. Add the Read NFC Action

• In the UI Design module, drag a Button element from the Elements panel on the left and drop it onto the app screen.
• In the button's properties panel, enter a phrase such as ‘Scan NFC’ in the Label field.

• Select the button and add the Device > Read NFC action from the + ADD ACTION menu according to the desired trigger event (Initial Actions, OnClick, OnBlur, etc.).

3. Testing the App

Tap the ‘Scan NFC’ button you created on the main screen.

• In the ‘Ready to Scan’ pop-up:
  
  • On Android devices, scan the NFC tag or card with the device.
  • On iOS devices, bring the back of the phone close to the NFC tag.
• The unique ID number from the NFC card will be read and become available in the app.

In a warehouse management app, employees can quickly transfer product information to the system by reading NFC tags on products on shelves. This makes product tracking easier and prevents manual data entry errors.

Adding an NFC Reading Action

Enter the

1. UI Design module and drag a Button element from the left panel and drop it on the screen.
2. Enter ‘Scan NFC’ in the Label property of the button.
3. Select the button and add the Initial Actions → Device → Read NFC action from the + ADD ACTION menu.

Data Processing After NFC Reading

• The Read NFC action opens the device's NFC reader when the button is clicked and reads the unique ID of the tag.
• The read ID can be used to search for product information in the application's database.
• If product information is found, the relevant details (name, stock status, etc.) can be dynamically displayed on the screen.

• Data Processing: The read NFC ID can be saved to the application's database or different actions can be triggered.
• Conditional Reading: NFC reading can be controlled based on user permissions or application status.
• Multiple Reading Scenarios: Multiple NFC tags can be read for different purposes within the same application.
• Error Management: Error handling mechanisms can be added to display appropriate messages to the user when reading fails.

Technical Risks

• Hardware Requirements: Actions will not work on devices without NFC reader hardware.
• Read Data Limitations: Only the UID of NFC tags can be read; access to advanced data blocks requires separate operations.
• User Permissions: The device must grant the necessary permissions for NFC reading.

The Read NFC action is a user-friendly and practical component in Kuika mobile applications that enables fast data acquisition from the physical world. It can be used effectively with proper configuration and testing.
