– Statement 2: NFC is designed for extremely short distances, typically a few centimeters (usually 4 cm or less), requiring devices to be tapped or brought very close together. A distance of “even a metre” is far beyond the normal operating range of NFC. This statement is incorrect.
– Statement 3: While NFC itself is a communication method, applications built on NFC can and commonly do incorporate strong encryption and other security protocols (like secure elements, tokenization for payments) to protect sensitive information during transactions. This statement is correct.
