Abstract: The present disclosure discloses a proximity-based secure communication system and method for digital transactions. The system comprises: a slave terminal with a near field communication (NFC) radio frequency communication channel, wherein the slave terminal remains in the listening mode in the NFC radio frequency communication channel; and a master electronic device with an NFC radio frequency communication channel. The slave terminal is configured to send an Answer-to-Reset (ATR) to the master electronic device when, by proximity, the slave terminal detects the activation of the NFC radio frequency channel. The slave terminal and the master electronic device exchange Application Protocol Data Unit (APDU) commands that represent a digital transaction by means of the NFC radio frequency channel, such that the master electronic device sends request APDU commands to the slave terminal, and the master electronic device receives reply APDU commands from the slave terminal.
