Abstract

A financial transaction card reader device includes a housing having a slot for swiping a magnetic stripe of a financial transaction card to complete a financial transaction between a buyer and seller. A read head is in the housing, reads data stored on the magnetic stripe and for produces a signal indicative of data stored on the magnetic stripe. An output jack is adapted to be inserted into a microphone input associated with a seller'"'"'s mobile device for providing the signal indicative of data stored on the magnetic stripe to the mobile device. The signal is decoded in the mobile device.

Claims

1. A financial transaction card reader device in communication with a payment system, comprising:

a housing having a slot for swiping a magnetic stripe of a financial transaction card to complete a financial transaction between a buyer and seller;

a read head in the housing for reading data stored on the magnetic stripe and for producing a signal indicative of data stored on the magnetic stripe;

an output jack configured to be inserted into a port of a seller'"'"'s mobile device and to provide the signal indicative of data stored on the magnetic stripe to the mobile device; and

circuitry including an encryption system for encrypting and providing at least a portion of the signal to the mobile device as encrypted.

2. The device of claim 1, further comprising:

providing a confirmation of payment to the buyer in response to completion of the financial transaction.

3. The device of claim 1, further comprising:

determining that the buyer is present with the seller at the time of the financial transaction.

4. The device of claim 1, wherein the financial transaction card is selected from at least one of:

credit financial transaction card, debit financial transaction card, gift financial transaction card, fund transfer financial transaction card, or other types of payment authenticating piece capable of carrying out the financial transaction.

5. The device of claim 1, wherein the mobile device is a portable electronic device that includes at least one of:

software, firmware, hardware, or a combination thereof, that is capable of at least receiving a signal, decoding the signal if required, exchange information with the payment system to verify the buyer and/or seller'"'"'s account information and conduct the transaction.

6. The device of claim 1, wherein the mobile device is a cell phone or a mobile digital device.

7. The device of claim 1, wherein the financial transaction is an electronic transaction conducted over the Internet or a financial transaction card present point-of-sale transaction where the buyer makes the purchase at a store front, other “

brick-and-mortar”

location, or in a presence of the seller.

8. The device of claim 1, wherein the signal includes financial transaction data selected from at least one of:

amount of the transaction, additional notes related to the transaction, authorization and/or signature of the buyer.

9. The device of claim 1, wherein the signal includes financial transaction card information selected from at least one of:

one or more of financial transaction card number, financial transaction card holder'"'"'s name, expiration date, and security code.

10. The device of claim 9, wherein the mobile device has an output jack and the financial transaction card reader device is configured to be coupled to the output jack.

11. The device of claim 1, wherein the read head includes a slot configured to receive and permit the financial transaction card to be swiped.

12. The device of claim 11, wherein the slot is configured to reduce torque applied on the card reader when the financial transaction card is swiped through the slot in order to maintain accuracy and reliability of the data read by read head.

13. The device of claim 1, wherein the signal produced is indicative of data stored on the magnetic stripe with minimum error via a single swipe of the financial transaction card.

14. The device of claim 1, further comprising:

passive ID circuitry in the housing of the read head to deliver a unique ID of the device to the mobile device.

15. The device of claim 1, wherein acceptance and initialization of incoming signals from a swipe of the financial transaction card are done until the signals reach a steady state, the financial transaction card swipe is detected once steady state is reached, and peaks in the incoming signals are identified when the financial transaction card swipe is detected.

16. The device of claim 1, wherein the financial transactions is completed without sharing financial transaction card information with the seller.

17. The device of claim 1, wherein, in response to a completion of a financial transaction, the payment system sends a receipt of the financial transaction to the buyer.

18. A method for conducting a financial transaction with a financial transaction card, comprising:

receiving a swipe of a financial transaction card through a slot in a card reader, the slot configured to receive the swipe of a magnetic stripe of the financial transaction card to process a financial transaction between a buyer and seller, wherein the card reader is coupled to a mobile device through an output jack of the card reader;

in response to receiving the swipe of the financial transaction card, producing, using the card reader, a signal indicative of data stored on the magnetic stripe of the financial transaction card;

encrypting, using an encryption system in the card reader, at least a portion of the signal; and

communicating, through the output jack of the card reader, the signal to the mobile device, the signal having at least a portion that has been encrypted.

19. The method of claim 18, further comprising:

sending confirmation of payment to the buyer in response to completion of the financial transaction.

20. The method of claim 18, further comprising:

confirming that the buyer is authorized to use the financial transaction card.

21. The method of claim 18, further comprising:

determining that the buyer is present with the seller at the time of the financial transaction.

22. The method of claim 18, further comprising:

confirming that payment is made with a communication channel of the buyer'"'"'s choice.

confirming payment with an electronic notification in the form selected from at least one of;

an email, SMS message, tweet (message delivered via Twitter), instant message, or communication within a social network.

24. The method of claim 18, wherein the mobile device is a seller'"'"'s mobile device.

25. The method of claim 24, wherein the financial transaction is an electronic transaction conducted over the Internet or a financial transaction card present point-of-sale transaction where the buyer makes the purchase at a store front, other “

brick-and-mortar”

location, or in presence of the seller.
