1. An electronic device, comprising:
a processor hosting an application;
a near-field communication device; and
a secure element distinct from the processor,
wherein the near-field communication device is configured to identify a type of a terminal emitting a polling frame, addressed to the application and received by the near-field communication device, by analyzing a type of the polling frame and generating an analysis result, and
wherein the electronic device is configured to compare the analysis result with at least one command received from the terminal during an implementation of an NFC transaction, wherein in response to the comparison result indicating that the type of sender is not reliable, the application refrains from sending critical data.
