Abstract

A decoding system has a decoding engine running on a mobile device. The decoding engine decodes signals produced from a read of a first party'"'"'s financial transaction card, accepts and initializes incoming signals from a read of a first party'"'"'s financial transaction card, and detects a read of the first party'"'"'s financial transaction card. The transaction engine receives as its input decoded first party'"'"'s financial transaction card information from the decoding engine, and serves as an intermediary between the first party and a second party, so that the first party does not have to share his/her financial transaction card information with the second party. A social network is in communication with the transaction engine.

Claims

1. A decoding system, comprising:

a decoding engine running on a mobile device, the decoding engine in operation decoding signals produced from a read of a buyer'"'"'s financial transaction card, the decoding engine in operation accepting and initializing incoming signals from the read of the buyer'"'"'s financial transaction card until the signals reach a steady state, detecting the read of the buyer'"'"'s financial transaction card once the incoming signals are in the steady state, identifying peaks in the incoming signals and digitizing identified peaks in the incoming signals into bits;

a transaction engine running on the mobile device and coupled to the decoding engine, the transaction engine in operation receiving as its input decoded buyer'"'"'s financial transaction card information from the decoding engine and serving as an intermediary between a buyer and a merchant, so that the buyer does not have to share his/her financial transaction card information with the merchant, wherein the decoding system is configured to be coupled to a social network; and

the transaction configured to be coupled to a payment system with the payment system able to create open tabs for one or more transactions between first parties and second parties.

2. The system of claim 1, wherein opening of a tab is a financial transaction mechanism for the buyer and the merchant to enter into a transaction using a financial instrument of the buyer, each of buyer and merchant being registered to conduct transactions with the payment system that includes a secure server, a product or service database, a user database and a transaction base, the payment service being in communication with a buyer financial account of a financial institution, the payment service being a non-affiliate of the financial institution.

3. The decoding system of claim 2, wherein the buyer'"'"'s mobile device includes identifying information of the second parties that are members of the social network.

4. The decoding system of claim 3, wherein the buyer communicates with at least some of the second parties using the buyer'"'"'s mobile device.

5. The decoding system of claim 2, further comprising:

a payment system in communication with the transaction engine.

6. The decoding system of claim 3, wherein a payment system is in communication with a buyer'"'"'s financial transaction card institution or a buyer'"'"'s financial account.

7. The decoding system of claim 6, wherein the payment system includes identifying information of second parties qualified to conduct business with the payment system.

8. The decoding system of claim 1 wherein the mobile device is a mobile digital device.

9. The decoding system of claim 1 wherein the incoming signals are generated by swiping of the buyer'"'"'s financial transaction card through a card reader configured to be coupled and de-coupled with the mobile device.

10. The decoding system of claim 9 wherein the incoming signals are of low quality due to one or more of:

low quality of data read from a single and/or low density track of a magnetic stripe of the card, sampling speed limitations of the mobile device, and noise introduced into the mobile device.

11. The decoding system of claim 1 wherein the decoding engine in operation detects presence of the read of the buyer'"'"'s financial transaction card by looking for points in the incoming signals that exceed a minimum signal amplitude threshold.

12. The decoding system of claim 1 wherein the decoding engine in operation detects presence of the read of the buyer'"'"'s financial transaction card by capturing signal of interest in the incoming signals via Fast Fourier Transform (FFT).

13. The decoding system of claim 1 wherein the decoding engine in operation detects the peaks in the incoming signals to be resistant to ringing in the incoming signals.

14. The decoding system of claim 1 wherein the decoding engine in operation detects the peaks in the incoming signals to be resistant to scratches in a card that cause slow quality or false peak information to manifest in the incoming signals.

15. The decoding system of claim 1 wherein the decoding engine in operation detects peaks in the incoming signals by looking for local maxima and minima within a window of digital samples.

16. The decoding system of claim 1 wherein the decoding engine in operation identifies a track from which data of the incoming signals are read through the read of the buyer'"'"'s financial transaction card when only one track of data in a magnetic stripe of the buyer'"'"'s financial transaction card is read.

17. The decoding system of claim 1 wherein the decoding engine in operation digitizes the identified peaks in the incoming signals into bits only by checking and comparing polarities of peaks.

18. The decoding system of claim 1 wherein the decoding engine in operation combines various peak detection and digitization approaches to cover various ranges of degradation in quality of input signals read.

19. The decoding system of claim 1 wherein the decoding engine in operation chooses and optimizes different process combinations and parameters depending on hardware platform of the mobile device.

20. The decoding system of claim 1 wherein the decoding engine in operation scales and adjusts decoding to account for at least one of, different amounts of noise, sampling speed variations, signal ringing, and a swipe direction of the buyer'"'"'s financial transaction card when a buyer'"'"'s financial card is swiped through a slot of a card reader.
