## Abstract

The invention relates to a method, and an arrangement (A) for identifying a purchaser (1) and a retailer (2) and per-forming an economical transaction between the purchaser (1) and the retailer (2) at a point of sale (21), where the purchaser (1) has a mobile device (11), and where the point of sale (21) communicates with a transaction system (3). The transaction system (3) transfers funds (31) from the purchaser to the retailer according to given information from the purchaser and the retailer. The inventive method, and arrangement comprise the steps of; the mobile device (11) reading an identity of the point of sale (24) by means of a at least one of a camera, and a radio frequency receiver comprised in the mobile device (11), the mobile device (11), and point of sale generates and transmits messages comprising the identity of the point of sale (24) and the identity of the mobile device (14) through different channels of communication. Furthermore, the invention comprises computer program products conducting the software code needed for the invention to be carried out.

## Claims

### Claim 1

an account aware transaction system receiving communication from both the point of sale, and the purchaser, the transaction system settling the transfer of payment from the purchaser to the retailer by signals transmitted through different channels of communication, whereby the transaction system receives communication from the point of sale through at least one of a wired first channel, and a wireless first channel of communication, and the transaction system receives communication from the mobile device via a second wireless radio frequency channel;
the transaction system providing each purchase with a unique reference identity;
the transaction system receiving at least one signed mobile device message that was generated and transmitted by said mobile device through the second channel, the message comprising the identity of the mobile device and the identity of the point of sale having been derived from a tag visually placed at the point of sale and read by the mobile device;
the transaction system receiving at least one point of sale message that was generated by automatic prompting and transmitted by the point of sale on the first channel independently from the mobile device message to the transaction system, the at least one point of sale message having a part comprising at least the identity of the point of sale and the sum to be paid by the purchaser;
the transaction system comparing the at least one point of sale message with the mobile device message to match the point of sale message with the mobile device message and deciding a match when the identity part of the point of sale message matches the identity part of the mobile device message;
the transaction system issuing a transaction matched signal to the mobile device; and
the transaction system receiving a go-ahead signal transmitted by the mobile device comprising approval from the purchaser of the sum to be paid and of a match between the point of sale identity and the mobile device identity, and the transaction system settling the payment by withdrawing payment from the purchaser, and crediting the account relating to the point of sale for the unique transaction reference provided to a single purchase.

### Claim 2 (depends on 1)

A method according to claim 1, wherein the transaction system prompts the purchaser to utilize a personal code on the mobile device to approve said sum to be paid.

### Claim 3 (depends on 1)

A method according to claim 1, wherein the visual tag is at least one of a bar code, a quick response code, a data matrix, RFID tag, and a proprietary code.

### Claim 4 (depends on 1)

A method according to claim 1, wherein the point of sale, is a point of sale portable device comprising at least one of a cellular telephone, smart phone, a laptop computer, a touchpad, and a stationary computer.

### Claim 5 (depends on 1)

A method according claim 1, wherein the point of sale is a cashier register, and that the cashier register is generating messages by prompting it.

### Claim 6 (depends on 1)

A method according to claim 1, wherein the transaction system prompts the point of sale to generate a receipt to the purchaser.

### Claim 7 (depends on 1)

A method according to claim 1, wherein the point of sale is a virtual point of sale.

### Claim 8 (depends on 1)

A method according to claim 1, wherein the point of sale is an online shop available on the Internet.

### Claim 9 (depends on 1)

A method according to claim 1, wherein the point of sale is a server related to the retailer, and that the transaction system receives at least one message that was generated by the server, and generates messages to the server.

### Claim 10 (depends on 1)

A computer program product comprising computer program code, which, when executed by a single point of sale enables said point of sale wherein parts relating to said point of sale conduct the method step of claim 1 in program code to perform the steps of:
transmitting its identity by prompting it to perform said transmission; and transmitting said identity to an account aware transaction system; and expecting a payment confirmation or denial.

### Claim 11 (depends on 1)

A computer program product comprising computer program code, which, when executed by an account aware transaction system enables said system to perform parts of said method step of claim 1 in program code to perform the steps of:
matching the transmitted identities from a mobile device, and a point of sale; settling the accounts in a purchase between a mobile device, and a point of sale;
and transmitting messages to said point of sale, and said mobile device.

### Claim 12 (depends on 1)

A method according to claim 1, wherein the identity of the point of sale received by the transaction system in the at least one signed mobile device message is obtained by the mobile device operated by the purchaser by at least one of; a camera photographing, or a radio frequency receiver reading the tag, and translating the tag into the identity of the point of sale.
