First Claim
1. A payment device configured to receive payment object information and to transmit the payment object information, the payment device comprising:
- a near field communication (NFC) antenna;
a driving circuit configured to drive the NFC antenna to create a first magnetic field that is capable of being load modulated by a NFC enabled payment object while the payment device is in a first mode and while a switch is closed;
the switch, wherein a first pole of the switch is coupled to the NFC antenna and a second pole of the switch is coupled to the driving circuit;
an integrated circuit payment object reader having one or more electrical contacts;
a load modulation subsystem connected to the NFC antenna; and
a microcontroller configured to, while the payment device is in the first mode, receive first payment object information via the NFC antenna from the NFC enabled payment object, and transmit the first payment object information to a merchant device,the microcontroller further configured to, while the payment device is in a second mode;
turn off the driving circuit by opening the switch,receive second payment object information from an integrated circuit of a payment card while the integrated circuit of the payment card electrically engages with the one or more electrical contacts of the integrated circuit payment object reader, andtransmit the second payment object information using a NFC protocol by instructing the load modulation subsystem to control the antenna to modulate a second magnetic field.

Abstract
A payment device for a point-of-sale system that is configured to operate in a reader mode and in a transmitter mode. When in a first (reader) mode of operation as a seller device, the payment device is configured to receive first payment object information from a first payment object, such as a near field communication (NFC) enabled payment object. When in the second (transmitter) mode of operation as a buyer device, the payment device is configured to receive second payment information from a second payment object, such as an integrated circuit (IC) enabled payment object, and to transmit the second payment object information using a NFC protocol. The payment device includes a NFC antenna and a driving circuit configured to drive the NFC antenna to create a magnetic field when in the first mode of operation.
