“…While read the white and black, QR Code has a function or error correcting. There are four level error correction has been defined that is L, M, Q and H. Lowest level that is L with maximum 7% error corrected, M level with maximum 15% error corrected, Q level with maximum 25% error corrected and H level with maximum 30% error corrected [2]. 7519) which is used to transmit information securely between nodes using JSON object [3].…”

Mobile attendance is used to record student attendance in a lecture class. This mobile app uses QR Code to identify students' ID. This app facilitates lecturers in recording the attendance of lecturers and students. The accuracy and speed of data can be used as one of the parameters for lecturers' performance according to the efforts that have been done. Lectures at UNS are not only in the classroom, but they also go to the field, to rice fields and even to swimming pools. Therefore it requires a tool that can accommodate the recording of student attendance in all places quickly. One of the proposed solutions is to provide mobile attendance. Mobile attendance application was developed with SDLC method by using Java as programming language, while the authentication uses JWT which integrated with Single Sign-On in UNS. The proposed mobile attendance system can record the QR Code attendance, recapitulate the number of students present and absent and recapitulate the number of lecturers present in the class. The application was tested for its usability using SUS and obtained SUS score of 82.183 with grade A.

“…QR Code has a function of an error correcting for miss reading that white is black. Error correcting is defined in 4 levels (L, M, Q and H); level L: about 7% or less errors can be corrected, level M: about 15% or less errors can be corrected, level Q: about 25% or less errors can be corrected, and level H: about 30% or less errors can be corrected [15].…”

A robust twofold zero-watermarking scheme for secret QR-Code (Quick Response Code) sharing is proposed in order to increase the security of commercial activities on the internet and media. In this paper we will present a twofold scheme for zerowatermarking to be used for copyright protection, implemented in discrete wavelet transform (DWT) as the first fold and discrete cosine transform (DCT) as a second fold for color images in which the visual secret sharing is used to generate unexpanded master and secret shares for the same QR-Code watermark. The experimental results indicate that the proposed scheme is highly robust and the QR-Code can be decodable even after different types of attack being applied.

“…A QR-code [4] is a two-dimensional "Quick Response" code invented by Denso Wave that can store website URLs, short messages, map sections or even vCard data depending on the size of the image. QR-codes range in size from a 21x21 array of information modules to 177x177 with a storage capacity of up to 4296 characters.…”

The packaged water segment in India has been witnessing rapid growth over the last decade as a result of increasing urbanization, skewed spatio-temporal distribution of freshwater resources and limitations in the municipal water supply infrastructure. However, growing demand for retail (<5L bottles) and bulk water (20L bottles) packages has also been accompanied by a rise in several thousands of new unregistered manufacturing units. Even for government certified manufacturers, weaknesses in the supply chain networks are being widely exploited by distributors and dealers to flood the market with poor quality imitations of leading bottled water brands. The paper describes the application of ICT in the form of task-based contextual QRcodes to promote the availability and consumption of healthy packaged water products. The proposed scheme improves end-to-end supply chain visibility for the certified manufacturer, enhances regulator's ability to catch potential licensing and quality violations, and empowers consumers with tools that rapidly detect fraudulent offerings.
