Provisioning multiple devices?

If you are provisioning multiple devices, you do not need to load the ID's and certificates every time. Once the ID's and keys have been loaded, they will stay loaded in the software until it is closed.

This means you can simply plug in a device, click "SAVE CONFIGURATION" and move onto the next device, making it a quick and easy task if you have a bulk configuration to complete.

Troubleshooting

Android or Apple NFC not working?
Click the Factory Reset button to reset and reboot the reader.

Device firmware

Please confirm the firmware is running the following version: VP3300 USB NEO v1.01.184

On Windows, this can be done by opening up the NFC config tool app, plugging in the device and checking the firmware version below the connected message

If the tool is not reading your device at all, you can also confirm this by finding the USB Input device in the device manager under "Human Interface Devices"
If there is more than one, you will have to go through them all until you find the correct one with vendor ID 0x0ACD

Please open the device and go to the "Details" tab and check the VID & PID as per below

Right click this and click "Properties" and then change to the "Details" tab. From here, please select the "Hardware Ids" option in the property menu.

The correct firmware should show the below: VID_0ACD & PID_3530
