NF4x Wireless RFID-NFC Reader Writer
The idChamp® NF4x wireless RFID-NFC reader/writer is used to wirelessly connect to the host device allowing reading RFID-NFC tags, and writing tags when tags are so enabled.
NF4x is available in physical variants:
- Battery-powered (rechargeable)
- Kiosk (powered by cable)
Each of the physical variants is also available in two modes:
- Smart Mode (required for writing NFC tags)
- Direct Mode (required to use in HID Keyboard mode)
To use the NF4x in Smart Mode requires an app that supports NF4x.
Apps that support NF4x are available here https://www.serialio.com/downloads
Some 3 rd party apps also support the NF4x.
To use the NF4x in Direct Mode no app is required since the NF4x simulates
Bluetooth keyboard.
Battery-powered NF4x has a 1800mAh battery that has a charge time from empty,
of about 4 hours using a USB cable.
The kiosk variant is powered by a standard USB-A to micro USB cable.
The following shows how to use the Mobile Grid Android app to connect to NF4x.
Power on the NF4 and the wireless Connection LED will blink
Launch the Mobile Grid app and tap the Serial Device Manager (SDM) icon
Tap the device connect icon to connect
If NF4 device is not In the list, tap the add device icon (+) then tap on the NF4 device when found
Once the device is connected to the host the data transfer LED (to left of connection LED) will blink indicating polling.
To read the RFID-NFC tag put it on top of the NF4 reader
RFID-NFC tag value(s) will be read according to the SDM settings for the device. The following shows reading the CSN Chip Serial Number (aka UID – Unit ID).
To write the RFID-NFC tag, open SDM for the connected NF4, this example will use the “WRITE NDEF DATA” option.
Select the type of NDEF data to write, this example uses type URL.
Put the NFC tag to the top of the NF4 (see Picture 3), and tap WRITE.
After write success, then read back can be done by setting the SDM to read NDEF data.
Pick User Data post type to show NDEF data.
To read the RFID-NFC tag put it on top of the NF4 reader (Picture 3) then the NDEF data will be posted
