Abstract
A secure smart card is described. The smart card can include a processor, a memory and a transceiver. The smart card can communicate with various terminals and store a digital signature and other information on the card. Another terminal can validate the information stored on the smart card using the digital signature. In certain embodiments, the terminal can also validate the information by using a blockchain. The advanced design of the smart card obviates the need for a network connection.
Claims21
1-20. (canceled)
A payment terminal comprising:
- a processor, a memory and a transceiver, wherein:
- the processor is configured to generate:
- a first signal including instructions to enable a card processor to store a set of data on a card memory of a card, wherein the set of data includes a count number;
- and
- a second signal including instructions to enable the card processor to update the set of data on the card memory, wherein the updating includes incrementing the count number by one unit;
- and
- the transceiver is configured to:
- transmit to the card the first signal and the second signal;
- and
- receive from the card a third signal including all the sets of data stored on the memory of the card.
The payment terminal of 22, wherein the processor is configured to:
- generate a second digital signature using the private key and the sets of data received from the card;
- and
- compare the digital signature with the second digital signature.
A payment card comprising:
- a processor, a memory and a transceiver, wherein:
- the transceiver is configured to receive a first signal and a second signal form a payment terminal and transmit a third signal to the payment terminal;
- the processor is configured to:
- in response to receiving the first signal, store a set of data on the memory of the payment card, wherein the set of data includes a count number;
- in response to receiving the second signal, update the set of data by incrementing the count number by one unit;
- and
- generate the third signal including all the sets of data stored on the memory of the payment card.
