On IAdea signboards, there are two ways to enable access to the NFC/HID reader. Please notice that IAdea device only support read and does NOT support the write feature.
1. Standard Android NFC API
This way is recommended for app developer.
Attachment is the sample code for Android NFC API. The sample app shows the card number when sense a card.
2. Keyboard mode enabled
When a card is detected by the reader, Android will send a text string reading from card as keyboard input.
This is the recommended method for HTML5 applications.
The default status for NFC keyboard mode on IAdea signboards is set as disabled. To enable keyboard mode, go through the following steps: Basic Setting -> Ethernet -> More (Wireless & network) -> NFC keyboard.
