Frequently Asked Questions

Make sure that there's nothing on the charging plate. Place your phone or other compatible device on the charging plate. When the white indicator light goes off, the battery is fully charged. It's normal for the plate and phone to get warm, and they may get even warmer if you use your phone to, for example, stream music while charging. Keep the area around the plate free. If there is something on the plate besides your phone, the phone doesn't charge, and the white indicator light blinks quickly.


The answer of course depends on your phone and the tag itself, but generally you need to be within a couple of centimetres (an inch). Fusion FNT-001 may detect it around 25.0mm.

That's the clever thing about NFC tags. They don't require batteries. They get their power from just being near a powered NFC device, for example a mobile phone.

Like the number of NFC enabled phones, the number of NFC Apps is growing quickly. For example, you can already download Apps which will allow you to encode tags to turn your phone's wifi or bluetooth on or off - or open your favourite weather page. Encode a tag for your office desk and just tap it to change all your phone settings.

The easiest way at the moment is to use an NFC enabled mobile phone such as the Nexus S running Android or a newer BlackBerry or Nokia. Just download a suitable App and you can be encoding your tags in minutes.

NFC tags can be locked so that once data has been written, it cannot be altered. For most tags this is a one way process so once the tag is locked it cannot be unlocked.
Encoding and locking are two separate actions. NFC tags can be re-encoded numerous times until they are locked.

There's a whole set of different data types you can store on an NFC tag. The actual amount of data varies depending on the type of NFC tag used - different tags have different memory capacities. For example, you may choose to store a URL (web address) or a telephone number. A standard Ultralight nfc tag can store a URL of around 41 characters, whereas the newer NTAG203 nfc tag can store a URL of around 132 characters.
Usually, this information is stored in a specific data format (NDEF - NFC data exchange format) so that it can be reliably read by most devices and mobile phones.

NFC (near field communication) is a wireless technology which allows for the transfer of data such as text or numbers between two NFC enabled devices. NFC tags, for example stickers or wristbands, contain small microchips with little aerials which can store a small amount of information for transfer to another NFC device, such as a mobile phone

Qi works through a well-established process called magnetic induction. You may remember magnetic induction from high school physics. Magnetic induction has been used for more than a century to make power transformers. Qi chargers have a built-in transmitting coil that intelligently communicates with Qi devices using a specific electromagnetic frequency, so any Qi device will work with any Qi charger, now and in the future.

Yes, every phone communicates with the WTU-050 differently. With certain phones, the green light will stay on as long as the ph

You can have a distance of 11.0 mm between the coils in the WTU-050 and the coil in your device.
