What’s the maximum distance for using NFC?

NFC operates through the magnetic induction with low power consumption, which requires a certain proximity between devices and tags interacting. Under ideal conditions, that is, without any electromagnetic interference, the maximum distance may be of up to 10 cm, but the effective maximum distance is of about 4 cm.

In our experiences, the ideal distance for reading NFC tags using mobile phones is of at most 1.5 cm. Despite it seems to be a very short distance, proximity is exactly what makes this technology relevant.
