Abstract

A read head is provided that is configured to be coupled to a mobile device. The read head has a slot for swiping a magnetic stripe of a financial transaction card. The slot is utilized for a financial transaction between a buyer and seller and reads data on the magnetic stripe. A signal is produced indicative of data stored on the magnetic stripe, An output jack of the read head is adapted to be inserted at least one of the audio input port or microphone input port of the mobile device. The output jack delivers the signal to the mobile device. A sampling rate of the signal at the audio input port or a line input port of the mobile device is at least 15 kHZ.

Claims

1. A card reader configured to be coupled to mobile device, comprising:

a housing,

a read head positioned in the housing, the card reader configured to be coupled to a mobile device to receive a signal, the card reader having a slot for swiping a magnetic stripe of a financial transaction card, the slot being utilized for a financial transaction between a buyer and seller, the card reader reading data on the magnetic stripe and producing a signal indicative of data stored on the magnetic stripe, card reader electronics that include a discharge subsystem to put the card reader in a power cycle, and a fake load to provide that the mobile device does not perceive a disconnect of the card reader from the mobile device when the card reader sends the signal to the mobile device; and

an output jack adapted to be coupled and de-coupled to at least one of an audio input port or microphone input port of the mobile device and delivering the signal to the mobile device.

2. The card reader of claim 1, wherein a sampling rate of the signal at the audio input port or the microphone input port of the mobile device is at least 20 kHz.

3. The card reader of claim 1, wherein a sampling rate of the signal at the audio input port or the microphone input port of the mobile device is at least 30 kHz.

4. The card reader of claim 1, wherein a sampling rate of the signal at the audio input port or the microphone input port of the mobile device is at least 40 kHz.

5. The card reader of claim 1, wherein a confirmation of payment is made to the buyer in response to completion of the financial transaction.

6. The card reader of claim 1, further comprising:

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

7. The card reader 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, and other types of payment authenticating piece capable of carrying out the financial transaction.

8. The card reader 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 a third party financial institution or payment network to verify the buyer and/or seller'"'"'s account information and conduct the financial transaction.

9. The card reader 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 a purchase at a store front, other “

brick-and-mortar”

location, or in a presence of the seller.

10. The card reader 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.

11. The card reader 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.

12. The card reader of claim 1, 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 card reader 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 card reader of claim 1, further comprising:

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

15. The card reader 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 card reader of claim 1, wherein the financial transaction is completed without sharing financial transaction card information with the seller.

17. The read head of claim 1, wherein a textured side of the read head matches a textured side of the card.

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

coupling a mobile device with an output jack of a card reader with a read head including card reader electronics with a discharge subsystem, and a fake load using the discharge system to put the card reader in a power cycle;

swiping the financial transaction card through a slot of the read head producing a signal indicative of data stored on a magnetic stripe on the financial transaction card;

sending the signal to the mobile device with the output jack;

using the fake load to provide that the mobile device does not perceive a disconnect of the card reader from the mobile device when the card reader sends the signal to the mobile device; and

sampling the signal at an audio input port or a microphone input port of the mobile device.

19. The method of claim 18, wherein the sampling rate of the signal at the audio input port or the microphone input port of the mobile device is at least 20 kHz.

20. The method of claim 18, wherein the sampling rate of the signal at the audio input port or the microphone input port of the mobile device is at least 30 kHz.

21. The method of claim 18, wherein the sampling rate of the signal at the audio input port or the microphone input port of the mobile device is at least 40 kHz.

22. The method of claim 18, further comprising:

communicating at least a portion of the data with a third party financial institution or payment network to authorize the transaction.

23. The method of claim 18, further comprising:
