## Abstract

A system and method of providing two-way communication between an isolated POS system and a website are described. The POS system operates as an air gap system. In response to detecting a trigger event the two-way communication is initiated for installation, diagnostic and repair services. POS information for transmission to the website through the internet is generated using a QR code that includes the website address and a data payload that depends on the desired service. The QR code is read by a smart phone and transmitted to the website. The website responds by sending response data dependent on the QR code and desired service. The response data is communicated to the POS system via another QR code for further operations by the POS system based thereon.

## Claims

### Claim 1

A method, comprising:
identifying, on a point of sale (POS) terminal, a trigger event associated with at least one of servicing or operation of the POS terminal, the trigger event associated with a group of errors that include a diagnostic error and a maintenance error;
generating, by the POS terminal, information relevant to the trigger event;
encoding, by the POS terminal, the information as encoded information;
providing, by the POS terminal, the encoded information to a mobile device;
receiving, by the POS terminal, response information from the mobile device; and
processing, by the POS terminal, the response information to at least partially resolve the trigger event on the terminal.

### Claim 2 (depends on 1)

The method of claim 1, wherein encoding further includes encoding the information in a Quick Response (QR) code.

### Claim 3 (depends on 2)

The method of claim 2, wherein providing further includes presenting the QR code on a display of the POS terminal for capture by a camera of the mobile device.

### Claim 4 (depends on 1)

The method of claim 1, wherein encoding further includes encoding the information in a near field communication (NFC) message.

### Claim 5 (depends on 1)

The method of claim 1, further comprising scraping POS software logs for a plurality of previous error codes immediately preceding a present error code associated with the trigger event, the information including the plurality of previous error codes and the present error code.

### Claim 6 (depends on 1)

The method of claim 1, wherein receiving further includes scanning a Quick Response (QR) code from a display of the mobile device and decoding the QR code to obtain the response information.

### Claim 7 (depends on 1)

The method of claim 1, wherein receiving further includes receive a near filed communication (NFC) message from the mobile device and obtaining the response information from the NFC message.

### Claim 8 (depends on 1)

The method of claim 1, wherein identifying further includes determining that the POS terminal lacks Internet connectivity based on the trigger event.

### Claim 9 (depends on 8)

The method of claim 8, wherein processing further includes establishing Internet connectivity after processing the response information received from the mobile device.

### Claim 10 (depends on 1)

The method of claim 1, wherein generating further includes providing a web address to a web site as a portion of the information with a remaining portion of the information associated with an identifier for the POS terminal and the trigger event.

### Claim 11 (depends on 1)

The method of claim 1, wherein processing further includes providing administrative access to the POS terminal based on a temporary password provided with the response information.

### Claim 12

A method, comprising:
obtaining, by a mobile device, a message from a point of sale (POS) terminal that lacks direct Internet connectivity;
providing, by the mobile device, at least a portion of the message to a server after identifying the server from another portion of the message;
receiving, by the mobile device, response information from the server; and
providing, by the mobile device, the response information to the POS terminal to resolve a trigger event associated with the POS terminal, the trigger event associated with at least one of servicing or operation of the POS terminal, the trigger event associated with a group of errors that include a diagnostic error and a maintenance error.

### Claim 13 (depends on 12)

The method of claim 12, wherein obtaining further includes scanning a Quick Response (QR) code presented on a display of the POS terminal for the trigger event, decoding the QR code and obtaining the message.

### Claim 14 (depends on 12)

The method of claim 12, wherein obtaining further includes obtaining a near field communication (NFC) message from the POS terminal and identifying the message from the NFC message.

### Claim 15 (depends on 12)

The method of claim 12, wherein providing the response information further includes, encoding the response information in a Quick Response (QR) code, and presenting the QR code on a display of the mobile device for scanning by the POS terminal.

### Claim 16 (depends on 12)

The method of claim 12, wherein providing the response information further includes sending the response information to the terminal as a near-field communication (NFC) message.

### Claim 17 (depends on 12)

The method of claim 12, wherein providing the response information to the terminal further includes causing the terminal to perform disk image recovery to resolve the trigger even based on the response information and providing a temporary password with the response information received from the server or a help desk.

### Claim 18 (depends on 12)

The method of claim 12, wherein, further comprising scraping POS software logs for a plurality of previous error codes immediately preceding a present error code associated with the trigger event, the information including the plurality of previous error codes and the present error code.

### Claim 19

A point of sale (POS) terminal, comprising:
a display; and
processing circuitry configured to perform operations, comprising:
detecting a trigger event causing an error condition on the POS terminal;
gathering diagnostic information associated with the error condition;
scraping POS software logs for a plurality of previous error codes immediately preceding a present error code associated with the trigger event;
generating a message that comprises a server address for a server, the diagnostic information for the error condition, and the plurality of previous error codes and the present error code;
creating an encoded message for the message;
providing the encoded message to a mobile device;
receiving response information from the mobile device, wherein the mobile device obtains the response information from the server using the server address in the encoded message; and
processing the response information to resolve the error condition.

### Claim 20 (depends on 19)

The POS terminal of claim 19, wherein the trigger event is associated with a group of errors that include a diagnostic error and a maintenance error.
