MiniCard not working?

Understanding the Limitations of Linq Minicards

Overview

The Linq Minicard is one of our most compact NFC products — designed for convenience and portability.
Because of its smaller size and design structure, it operates a little differently than full-size Linq Cards or Tags.

While Minicards function with the same Linq technology, they have smaller NFC antennas, which can affect read strength and consistency depending on how and where they are used.

Common Limitations

1. Reduced NFC Range

  • The minicard’s smaller antenna means it has a weaker NFC field compared to full-size Linq Cards.

  • Phones may need to be held closer or at a more specific angle to detect it.

  • This is normal behavior and not a sign of defect.

💡 Tip: Hold the minicard flat against the back of the phone rather than at an angle to improve detection.

2. Placement Sensitivity

  • NFC readers are located in different spots on each phone model.

  • On iPhones, the NFC reader is near the top ¼ of the device.

  • On Androids, it’s usually near the center or middle-back area.

  • Placing the minicard in the wrong position (like near a phone case magnet) can block the NFC signal.

🧠 Try this: Move the minicard slowly around the back of the phone until the NFC scan registers.

3. Material Interference

  • Metal cases, wallets, or lanyards can block or weaken the NFC signal.

  • If your minicard is attached to a metal keychain or badge clip, it may not read as easily.

  • For best results, attach your minicard to non-metal materials (plastic, silicone, or fabric).

4. Limited Customization Area

  • Because of its smaller size, minicards have less space for engraving or printed designs.

  • Only limited branding or logos may be available depending on your design and color choice.

Best Practices for Reliable Scans

✅ Hold the minicard flat against the back of the phone.
✅ Keep it away from metal surfaces.
✅ Test scan locations on both iPhone and Android to learn ideal placement, activate before applying to device..
✅ If using a case, try removing it temporarily to improve detection.

When to Consider a Full Linq Card

If you frequently use your Linq product in networking settings or public events, a full-size Linq Card may provide a stronger, more reliable tap experience.

  • Full-size cards have larger antennas, improving read distance and scan consistency.

  • They’re ideal for professional use, events, and high-traffic situations.
