1. BEFORE YOU START
Ensure you have an Android phone or tablet with NFC (Near Field Communication) – a list of NFC
enabled phones is available here:
If you have a barcode scanner app on your phone you can use it to
download the RFID Logger app from Google Play by scanning the QR Code
to the right or visit:
Ensure that the NFC is turned on. You can do this under Settings –>
Wireless & Networks (You may have to select the “More..” option) –>
NFC. Check the box to enable NFC.
Remove any case on your phone or tablet that may interfere with the NFC
communication – specifically any case that has metal or carbon in it.
Know where the NFC antenna is on your device. On some devices it is critical that the RFID Logger be
placed exactly in the NFC antennae for reliable communication. If you do not know the location you can
find it using the trial and success method by moving the Logger around the back of your phone or tablet
until you hear the NFC connect tone from your device (Ensure your volume is turned up). You may have
to fine tune the location to get reliable communication. See
2. READING AND WRITING
The logger uses near field communication (NFC) to communicate with Android devices that have NFC
capability. Near field communication is a form of low-power radio communication that is effective only
when the devices are in close proximity to one another (touching). The logger has a small antenna that
needs to be within the field of the companion device. Communication is position dependent.
The antenna coil in the logger is between the
button and the loop handle at the top of the
device. You need to know where the antenna
coil is on your phone/tablet, and ensure that
the logger antenna coil is within that coil.
Keep the logger close to your Android device
with the logger antenna coil in the NFC Area of
the Android device. If possible keep the logger
battery away from the NFC field as it may
interfere with the communications. See
diagram to the right.
