1. A self-powered semi-active electronic tag with autonomous processing capacity configured to perform a communication procedure, which comprises a nanochip and antennas, an electromagnetic power supply, and is configured to perform a two way direct communication procedure with another device of the same type and to communicate via Wi-Fi/Bluetooth to the Internet to connect with a blockchain, identifying machine-to-machine or machine-to-user transactions, and whose process is carried out in three stages, wherein the electronic tag is capable of generating its own chain of custody, processing, and transmitting information and notifications between tags and between the latter and authorized networks;
the electronic tag comprising:
two receiving and transmitting antennas, of which a first antenna picks up and couples the electromagnetic signal that is in the air, with the harvesting and energy storage module and receives and transmits the data provided by an electromagnetic (EM) module through Wi-Fi/Bluetooth to the Internet and blockchain;
an electronic device which in turn comprises:
two (EM) modules,
a harvesting and energy storage module,
a processing module and communication protocol,
one memory module,
the communication procedure being for recording, reading, writing, processing, storing and exchanging data and information comprising three stages:
in the first stage, the electromagnetic wave, which contains energy and data, is captured by the first antenna of the tag, which carries the wave simultaneously to t harvesting and energy storage module, which is responsible for providing energy to the various components of the electronic circuit and to one EM module of the two (EM) modules, which is responsible or demodulating a carrier signal to obtain data and information; once the signal has been demodulated, the processing module executes the different instructions, according to established transaction rules, and stores the information in the memory, thus capturing, processing and storing the transaction information coming from a service that generates the transaction rules, allowing the execution of consecutive quasi-simultaneous transactions; said processing module has the capacity to execute intelligent transaction rules, interoperating with blockchain technologies; said processing module generates its own chain of custody, processing and transmitting information and notifications between tags and between these and authorized networks; wherein the transaction rules are conditions provided and stored in the memory that must be met for the transaction to be executed;
a second stage, for the execution of the transaction, according to the transaction rules, a processor reads the data from the memory and sends it to another EM module of the two EM modules, which modulates the carrier frequency to be transmitted by the second antenna to the other tag of the same type, to establish the communication process; in this stage, the transaction between both tags is validated and confirmed based on the use of a secure communication protocol and an asynchronous protocol to confirm the execution of the transaction; said processing module is capable of transmitting data and information grouped into blocks or transmission lines with its own encrypted communication protocol, without the need to use other data networks;
a third stage is the confirmation of the execution of the initial transaction rules; for this purpose, the processing module takes the data of the confirmed transaction from the memory module, sends it to the EM module to modulate the carrier frequency and its corresponding transmission through the first antenna to the service that records the transaction;
wherein the processing module is able to collect data regarding the conditions of the transaction rules in the memory and blockchain through the Wi-Fi/Bluetooth connection to the Internet from the EM module and the first antenna;
wherein the self-powered semi-active electronic tag is able to maintain by itself, a record of time and place of the transactions carried out, which allows for proper traceability.
