Frequently Asked Questions (FAQ)

Q1: What is an NFC Amulet?

A1: It's an amulet equipped with Near Field Communication (NFC) technology, embedding a contactless IC tag. By simply tapping your smartphone, you can read pre-written information (e.g., website URLs). Unlike QR codes, there's no need to launch a camera and focus; its characteristic is the simple "tap-to-use" operation.

Q2: What smartphones can be used with it?

A2: NFC functionality is available on iPhone 7 and later models. For iPhone XS/XR and later models with iOS 13.1 or higher, automatic reading is possible without launching a dedicated app.

Many Android smartphones support NFC. Please check your smartphone's "Settings" under "Connected devices" or "Wireless & networks" to ensure "NFC" functionality is turned on. If NFC functionality is not found, your device may not support NFC.

Q3: My smartphone does not react when I tap the amulet. What should I do?

A3: Several reasons may be considered. Please check the following points:

Is NFC functionality turned on? Confirm that NFC is enabled in your smartphone's settings.
Are you holding it in the correct position? The NFC antenna location varies by smartphone. On Android, it's often near the center of the back; on iPhone, it's usually near the camera. Try moving it slightly to find the sweet spot.
Is your smartphone in sleep mode? Please hold it when the screen is on.
Is power-saving mode enabled? If power-saving mode is active, NFC functionality may be restricted. Please charge your phone and disable power-saving mode before trying again.
Is your smartphone case or other IC cards interfering? Try removing the case or moving other IC cards away.
Is the NFC Amulet directly attached to a metal surface? Metal can interfere with radio waves, making reading difficult. Unless it's a metal-compatible NFC tag, keep it away from metal surfaces.
Is the NFC Amulet damaged? In rare cases, the tag itself might be faulty.
