|
|
Gives anything its attached to a special meaning. All spells have implanted nfc so they can have a special meaning.
|
||
|
|
|
||
|
|
Ergo, the spells/sigils change the way users think about spaces, but through nfc interfaces the spells can also have actual impact.
|
||
|
|
|
||
|
|
Also every user could have his/her own sigil to interact with certain thinks.
|

> I've been playing with NFC & RFID for the last couple of months (but am by no means an expert) and I don't think you'll have any issues.

|
> NFC operates through changes in the magnetic field; static magnets shouldn't affect it too much.

The effect of four NdFeB magnets (two spherical magnets 8 and 10 mm in diameter, a necklace made of 45 spherical magnets, and a magnetic name tag) was tested in forty-one ambulatory patients with a pacemaker and 29 patients with an ICD. The maximum distance at which the magnetic switch of a device was influenced was observed.
|
||
|
|
|
||
|
|
> Results:
|
||
|
|
> Magnetic interference was observed in all patients.
|
||
|
|
> The maximum distance resulting in device interference was 3 cm.
|
||
|
|
> No significant differences were found with respect to device manufacturer and device types.
