Abstract

A smartcard communicating simultaneously with a smart phone and a point of sale, thereby allowing the smartcard to act as a bridge between the point of sale and the smart phone. The smart card is typically powered by the point of sale and typically communicates with the smart phone using BLUETOOTH Low Energy (BLE).

Claims

1. A method for using a smart card comprising control logic, a contact interface, and a contactless interface as a bridge between a point of sale device and a smart phone, the method comprising:

providing power to the smart card from the point of sale device via one of the contact interface and the contactless interface;

determining, using the control logic, which interface is receiving the power from the point of sale device;

initiating an appropriate activation sequence for the interface receiving power; and

establishing a communication link between the point of sale device and the smart phone via the smart card.

2. The method of claim 1, where the contact interface is an ISO 7816 interface type.

3. The method of claim 1, where the contactless interface is an ISO 14443 interface type.

4. The method of claim 1, further comprising:

establishing a second communication link between the smart phone and a virtual secure element in a cloud.

5. A method of using a smart card as an adaptor, the method comprising:

providing power to the smart card from a point of sale device via one of a contact interface and a contactless interface;

determining, using control logic, which interface is receiving the power from the point of sale device, wherein both the contact interface and the contactless interface are coupled to the control logic;

selecting an appropriate communication protocol;

determining whether a smart phone having BLE capability is available; and

setting up a communication link between the point of sale device and a secure element of the smart card when the smart phone having BLE capability is not available, wherein the secure element is coupled to the control logic.

6. A method of using a smart card as an adaptor, the method comprising:

providing power to the smart card from a point of sale device via one of a contact interface and a contactless interface;

determining, using the control logic, which interface is receiving the power from the point of sale device, wherein both the contact interface and the contactless interface are coupled to the control logic;

selecting an appropriate communication protocol;

determining whether a smart phone having BLE capability is available; and

setting up a first communication link between the point of sale device and the secure element of the smart card and a second communication link between the secure element and a wireless low power short range connectivity low energy interface when the smart phone having BLE capability is available, wherein the secure element is coupled to the control logic.
