System and apparatus for encrypted data collection using rfid cards

A method comprising:

• transmitting a first signal from a terminal to a smart card, wherein:
• the terminal includes a processor, a transceiver and an antenna;
• the first signal is transmitted from the antenna of the terminal and the first signal is configured to power up the smart card;
• transmitting, from the terminal to the smart card, a second signal including instructions to enable a processor and a memory of the smart card to store a set of data on the memory of the smart card, wherein:
• the second signal includes the set of data;
• the set of data includes a location identification number, a time, a count number and a digital signature;
• transmitting, to the smart card, a third signal from the terminal, wherein the third signal is transmitted by the antenna of the terminal and the third signal is configured to power up the smart card;
• and
• receiving, at the terminal from the smart card, a fourth signal, wherein the fourth signal includes all the sets of data stored on the memory of the smart card.

A method comprising:

• receiving, at a host computer from a first terminal, a set of data including a first location identification number, a first time and a first count number, wherein the terminal forwarded this set of data to the host computer in response to scanning a smart card at the first terminal;
• storing the set of data in a blockchain;
• receiving, at the host computer from a second terminal, a plurality of sets of data each set including a location identification numbers, a time and a count number, wherein the second terminal forwarded this plurality of sets of data to the host computer in response to scanning the smart card at the second terminal;
• comparing each of the sets of the plurality of the sets of data with the sets of data stored in the blockchain;
• determine the authenticity of the plurality of the sets of data if the plurality of the sets of data match the sets of data stored in the blockchain;
• in response to establishing the authenticity of the plurality of the sets of data, transmitting a signal to the second terminal indicating that the plurality of the sets of data is authentic, and in response to failing to establish the authenticity of the plurality of the sets of data, transmitting a signal to the second terminal indicating that the plurality of the sets of data is not authentic.
