Consider the following statements with reference to the Near Field Communication (NFC) Technology:

1. In NFC technology, the communication between the devices is done using the waves which have wavelength shorter or near to the visible light.

2.Since the NFC technology works among the devices in close proximities, it is completely free of security risk.

3. Reading information from smart posters is done using the NFC technology.

Explanation:

Incorrect. Near Field Communication (NFC) technology does not use waves with wavelengths near or shorter than visible light. Instead, NFC operates at radio frequencies, specifically at 13.56 MHz, which is in the radio wave spectrum, far from the wavelengths of visible light.

Incorrect. While NFC technology works among devices in close proximity (typically a few centimeters), stating it is completely free of security risks is misleading. No wireless communication technology is entirely devoid of security risks. NFC does have security features, but it is still susceptible to risks like eavesdropping, data modification, and relay attacks, although the close proximity required for communication does reduce these risks compared to other wireless technologies.

Correct. NFC technology is used for reading information from smart posters. Smart posters embedded with NFC tags can communicate with NFC-enabled devices, allowing users to access additional information, websites, or other digital resources by tapping their devices against the posters.

Therefore, only one of the statements is correct.
