  • Blue Bite Account
    • NFC mTAGs in your account
  • Android phone with NFC reader
  • Unlocked NFC inlays with NXP nTAG 21x chips
  • A desktop program that can open and save .CSV files as a spreadsheet
    • MS Excel, Numbers, Google Sheets


Prepare an NFC Encode CSV file

1. On the mTAG page, locate the objects that should be encoded to an NFC Inlay. Here is a quick link to locate NFC mTAGs.

2. Export the mTAG

3. Open the file in a spreadsheet program. Navigate to the column header 'n_url'. Each URLs will be encoded to an individual NFC inlay.

4. Open the NFC Encode Template. Download it here.

5. Copy the URLs from Step 3, and paste them into the NFC Encode Template, Column B. Copy the predefined settings from row 1 to all the rows.

6. Save this file as a .csv, then send it to your phone.

Prepare your Android phone to encode NFC inlays

1. Open NXP TagWriter. Download it here.

2. Download the NFC Encode Template file–with a row filled out for each URL–to your phone

Tap Each NFC inlay with your phone

Follow these instructions to configure NXP TagWriter and encode NFC inlays.

Please Note: Choose "Protection > Lock" and encoding an NFC inlay is an irreversible action. Once encoded, the inlays will not be able to be edited. Encode a few inlays without it until you are comfortable with such an action.
