NFC Transmission Guide for VidaBay E Ink Fridge Magnet

With a battery-free design, our E Ink fridge magnet delivers energy supply and data transmission exclusively via NFC induction. A stable, close fit between your phone and the magnet is critical for successful transmission, and this guide will help you achieve consistent results, whether you’re setting up for the first time or troubleshooting issues.

Key Rules for Reliable Transmission

1. Note for iPhone 15/16 Series Users: The titanium rear cover of these models may slightly weaken NFC signal strength. This is not a product defect, and can be easily optimized with the operations below.

2. No Flat-Surface Transmission: Never place the phone and fridge magnet on a hard flat surface (e.g. a desktop) during transmission. Even a small gap will disrupt the NFC connection, and interfere with power intake for this battery-free device.

3. Correct Transmission Operation: Squeeze the phone and fridge magnet tightly together with your hand throughout the full transmission process. This eliminates gaps between NFC antennas, stabilizes the signal, and greatly improves transmission success rate — especially for iPhone 15/16 series users.
