THE METHOD OF SINGLE-USE PROCESSING OF DATA SAVED IN A QUICK RESPONSE (QR) CODE

Abstract

The method of single-use processing of data saved in a Quick Response (QR) code is the invention that consist in that, after scanning the QR code with a device equipped with a camera and extracting from it the data, the obtained data is analysed in order to check whether the data saved in the QR code have not been used already, and if it have not, the data is used in the IT system (for example mobile application, web application), and after that the data is deactivated, which prevent it from further usage. The invention can be used in loyalty program, because it allows for sending to the participants of the loyalty program cards containing the QR code, which, upon scanning, will grant to the user points in the loyalty program. Apart from that this invention make it also easier and faster to top-up phones.

Claims

1. The method of single-use processing of data saved in the QR, characterized in that by using a scanning module to obtain the image of the QR code, which is then decoded using a decoding module for the purpose of extracting information saved in the QR code, and the obtained information is transferred to data processing module, in which transferred information is analysed, and in cases when the data has not been used previously, is used in the IT system, and subsequently—after using it—the data is deactivated in the data deactivation module, which makes using the data saved in the code again impossible, whereas this can be done either with a single processing module or separate modules—for data analysis, data use and data deactivation.

Description

[0018] This invention can also be used to make it easier and faster to top-up phones. Instead of tediously re-typing the code in the phone you could quickly scan the ward with a QR code, which holds the data required for topping up the phone. Single-use processing of data saved in a QR code will ensure that there is no possibility of a repeated top up of the phone using the same card with QR code.

[0019] The method of reading and processing data according to the invention consists in that, by using a scanning module (1) a picture of the QR code is obtained, which is then decoded using a decoding module (2) in order to extract information (data) saved in the QR code. The obtained data will be sent to the data processing module, in which they are analysed (3) in order to check whether the data saved in the QR code have not already been used and, if the data have not yet been used, the data saved in the QR code (4) is used in the IT system (web application, mobile application). Next—after using the data saved in the QR code—such data will be deactivated in the deactivation module (5). The data analysis module, the data usage module, and the data deactivation module may appear as one module fulfilling three functions, in which the entire process of processing data saved in the QR code takes place. The data analysis module, the data usage module, and the data deactivation module may also appear as independent modules in the IT system, as well as the analysis and usage modules may be one module, while the deactivation module will be a separate module. If when the analysis, usage, and deactivation module appear as one data processing module, in the case where during the data analysis it turns out that the data has already been used, the data processing will not continue. However, when the analysis module, usage module, and deactivation module appear as three independent modules, in the case where during the data analysis it turns out that the data has already been used, the data will not be sent to the data usage module.

[0020] To sum it up, the whole action will go down as follows: [0021] 1) scanning the code—obtaining the image of QR code, [0022] 2) de-coding the code—reading the data saved in the QR code, [0023] 3) data processing—processing the data saved in the QR code in the IT system (for example mobile application, web application), the first stage of data processing is analysis of data for the purposes of verification, whether the data saved in the QR code has been used previously. If the data has not been used previously, it will be processed in the IT system. If the data has been used previously, it will not be processed further in the IT system. The last stage of data processing is deactivation, preventing its future use by removing the data from the IT system, or tagging the data in a way that would allow the user to unambiguously determine during further analysis of data saved in the QR code, whether the data has been used previously.
