Abstract: A decoding system with a decoding engine running on a tablet. The decoding engine decodes signals produced from a read of a buyer's financial transaction card, accepts and initializes incoming signals from a read of a buyer's financial transaction card until the signals reach a steady state, detects the read of the buyer's financial transaction card once the incoming signals are in a steady stat, identifies peaks in the incoming signals and digitizes the identified peaks in the incoming signals into bits. A transaction engine runs on the tablet and is coupled to the decoding engine.

Abstract: A decoding system, with a decoding engine, runs on a mobile device. The decoding engine decodes signals produced from a read of a first party's financial transaction card. The decoding engine accepts and initializes incoming signals from a read of the first party's financial transaction card until the signals reach a steady state, identifies peaks in the incoming signals and digitizes the identified peaks into bits. A transaction engine is coupled to the decoding engine. 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. The first party does not have to share his/her financial transaction card information with the second party. The transaction engine is configured to be coupled to a payment system and a first party's financial transaction card institution or a first party's financial account.

Abstract: A decoding system includes a decoding engine running on a mobile device that decodes signals produced from a read of a first party's financial transaction card. The decoding engine accepts and initializes incoming signals from a read of the first party's financial transaction card until the signals reach a steady state, detects the read once the incoming signals are in a steady state, identifies peaks in the incoming signals and digitizes the identified peaks in the incoming signals into bits. A transaction engine runs on the mobile device and is coupled to the decoding engine. 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.

Abstract: A method of paying a second party is provided. A first party accesses the names of one or more qualified second parties. The second parties (i) have an association with the payment service, and (ii) if they do not have an established association with the payment service have established one prior to payment. The first party has an association with the payment service. A tab is opened by the first party that can be selected by the second party at any geographic location of a first party's mobile device. The second party is only able to charge a first party's financial account when the first party's mobile device is within a defined geographic area. The tab is a relationship between the first party, payment service and second party. The second party can engage in a financial transaction when the first party is within the defined geographic area.

Abstract: A decoding system runs on a mobile device and is coupled to a payment system. The decoding engine decodes signals produced from a read of a first party's financial transaction card. A transaction engine runs on the mobile device and is coupled to the decoding engine. The transaction engine receives as its input decoded first party's financial transaction card information from the decoding engine. A payment system, in communication with the transaction engine, includes at least one of, a user database, a product database, and transaction database.

Abstract: A method of processing a transaction between a customer and a merchant includes receiving from a mobile device of the customer or from another device of the customer an indication of consent to perform a cardless payment transaction with the merchant, receiving from the mobile device an indication that the customer is within a predetermined distance of the merchant, after receiving both the indication of consent and the indication that the customer is within the predetermined distance, sending to a computer system of the merchant an indication of the presence of the customer and personal identifying information for the customer, receiving data indicating a transaction between the customer and the merchant, and submitting the transaction to a financial service for authorization.

Abstract: A method is providing of paying second parties where if f they do not have an established association with the payment service, have an established association with the payment service prior to payment. The first party has an association with the payment service. A tab is opened by the first party that can be selected by the qualified second party at any geographic location of a first party's mobile device. The qualified second party is only able to charge a first party's financial account when the first party's mobile device is within a defined geographic area. The tab is a relationship between the first party, the payment service and the qualified second party. The qualified second party can engage in a financial transaction with the first party when the first party is within the defined geographic area.
