View Patent ↗In accordance with the present invention, a method and an apparatus are provided wherein a device is disabled if the device is located more then a predetermined distance away from the owner. Accordingly, a lost or stolen device is rendered unusable. The device has coupled thereto a receiver or transceiver. A transmitter or transceiver is located separately from the device. When the receiver and transmitter can communicate, the device is usable, when the receiver and transmitter cannot communicate, the receiver disables the device, rendering the device unusable.
1. A computer-implemented method comprising:
initiating, by a financial transaction card, a financial transaction by transmitting at least one signal to an authorized holder transceiver;
allowing, by the financial transaction card, the financial transaction responsive to receiving a reply from the authorized holder transceiver; and
disallowing, by the financial transaction card, the financial transaction by disabling a magnetic strip on the financial transaction card responsive to not receiving a reply from the authorized holder transceiver.
2. The computer-implemented method as recited by claim 1 , wherein the financial transaction card comprises a credit card, a debit card, or a gift card.
3. The computer-implemented method as recited by claim 1 , wherein the at least one signal is transmitted at a periodic time interval.
4. The computer-implemented method as recited by claim 1 , wherein the at least one signal is transmitted using an Industrial-Scientific-Medical (ISM) frequency.
5. The computer-implemented method as recited by claim 1 , wherein the authorized holder transceiver is configured to be carried by an authorized card holder.
6. The computer-implemented method as recited by claim 1 , wherein the disallowing the financial transaction comprises disabling the financial transaction card.
7. The computer-implemented method as recited by claim 1 , wherein the authorized holder transceiver is configured to be powered passively.
8. The computer-implemented method as recited by claim 1 , wherein the at least one signal contains an identifier configured to identify the authorized holder transceiver.
9. The computer-implemented method as recited by claim 8 , further comprising receiving, by the financial transaction card, a reply from the authorized holder transceiver, wherein the authorized holder transceiver is configured to transmit a reply responsive to receiving a signal containing the identifier.
10. A tangible computer-readable medium having instructions stored thereon, the instructions comprising:
instructions for initiating, with a financial transaction card, a financial transaction by transmitting a signal from the financial transaction card to one or more transceivers, wherein at least one of the one or more transceivers comprises an authorized holder transceiver;
instructions for allowing the financial transaction to be performed with the financial transaction card responsive to receiving a reply to the signal, wherein the reply comprises at least one identifier configured to identify at least one authorized holder transceiver; and
instructions for disallowing the financial transaction from being performed with the financial transaction card by disabling a magnetic strip on the financial transaction card responsive to not receiving a reply to the signal.
11. The tangible computer-readable medium as recited by claim 10 , wherein the financial transaction card comprises a credit card, a debit card, or a gift card.
12. The tangible computer-readable medium as recited by claim 10 , wherein the signal is transmitted at a periodic time interval.
13. The tangible computer-readable medium as recited by claim 10 , wherein the at least one authorized holder transceiver is configured to be carried by an authorized card user.
14. The tangible computer-readable medium as recited by claim 10 , wherein the not receiving a reply to the signal comprises not receiving a reply from at least one identified authorized holder transceiver.
15. A financial transaction card comprising:
a memory device embodying one or more instructions for allowing or disallowing a financial transaction to be performed with the financial transaction card; and
a transceiver coupled to the memory device, wherein the transceiver is configured to initiate a financial transaction by transmitting a signal to an authorized holder transceiver;
wherein the one or more instructions allow or disallow a financial transaction to be performed with the financial transaction card based on whether a reply is or is not received, respectively, to the signal, and wherein the one or more instructions disallow a financial transaction by disabling a magnetic strip on the financial transaction card.
16. The financial transaction card as recited in claim 15 , wherein the transceiver is further configured to transmit the signal at a recurring time interval.
17. The financial transaction card as recited in claim 15 , wherein the transceiver is powered passively.
18. The financial transaction card as recited in claim 15 , wherein the transceiver is a radio frequency transceiver configured to transmit the signal using an Industrial-Scientific-Medical (ISM) frequency.
19. The financial transaction card as recited in claim 15 , wherein the one or more instructions disallow a financial transaction by disabling the memory device.
20. The financial transaction card as recited in claim 19 , further comprising one or more instructions for enabling the memory device responsive to receiving a signal from an authorized holder transceiver.
