BACKGROUND AND BEAUTY SCHOOL APPLICATION
R codes—Quick Response Codes—seem to be everywhere right now. They are increasingly used in restaurant menus, on taxis, on business cards and in retail stores. They are found on posters, signs, magazines, newspapers, billboards and store fronts in Asia and Europe, and increasingly
number, or send an email or text message, in response to what has been pre-coded into the QR graphic. It can also direct the user to a YouTube video or to a Google map plat.
Downloading a QR Reader App to a Smartphone
To install a QR reader, go to www.mobile-barcodes.com/qrcodesoftware and access the Quick-Find Reader icon in the upper right corner of the page. This step is important since not all reader apps will function universally with all phone brands. Downloading the one specific reader that best fits a user’s camera brand is a good first step to success. Otherwise, it is likely that nothing at all can be read with the code reader, even though it might have been successfully downloaded. Users can Google search for “QR code reader for iPhone” or something similar, but the interactive site shown above saves time and is more likely to produce a workable code reader match for most smartphones.
in the U.S. Developed in 1994 by Toyota subsidiary Denso-Wave, the codes were originally used to track parts movement in vehicle manufacturing. Designed to allow its contents to be decoded at high speed, the QR code is now one of the most popular types of two-dimensional barcodes. See www.denso-wave.com/qrcode/ aboutqr-e.html for more background on the history and standards involved in the code evolution. While usually shown as black lines and squares on a white background, the codes may also be designed in color. See custom creations at www.qrmediacodes.com/customised-qr-codes. html for examples of color use. So, what do the codes mean, how are they “read,” how are they created, and how can they be used in teaching and learning?
Reading a Code with a Smartphone
1. Open the code reader app on the smartphone by touching the reader icon. When the app loads and begins to function (this could take a minute), it should automatically activate a phone’s camera. At this point, patiently waiting for action is important. 2. Center the QR code image to be read so that it is positioned within the camera’s lighted reading frame that appears on the smartphone screen. 3. When the image is positioned within the camera’s reading frame, the data within the code will take the user to whatever information has been “created” as the content within the QR code. Again, patiently waiting is helpful at this point; the app needs time to perform its function.
Understanding the Quick Response Code
A QR code (square in proportion) is a two-dimensional graphic image that contains some kind of data. It is not the traditional supermarket bar code that displays a series of straight lines typically seen on packaged products. This image has a border, and the data stored inside the border is the part that is read (some say “scanned”) by a smartphone that has a camera function and an already downloaded QR code reader app.
Reading (Scanning) a QR Code
A QR code reader application that has been pre-downloaded to a smartphone directs the smartphone camera to read the code when the reader application is open and the camera is focused on the code graphic. The phone user does not usually touch any camera icons to activate the camera reader function; the smartphone app initiates its own action, produces a lighted frame finder image on the phone screen, and then the reading of the code automatically begins. The user also does not usually “take a picture” by touching any camera icons. Rather, the application launches and initiates the reading action, on its own, without human interaction. As the smartphone app reads the code, the code data can direct the phone to open another web page, dial a telephone

Creating a QR Code
Content to be read by a smartphone camera must first be created by a different application called a QR Code Generator. Various presentation methods can be of use in education— either an online image that can be read by students directly from the computer monitor or big screen, or a printed image to be distributed to students with, say, questions for analysis also printed on that same sheet. Several sites offer QR code creation: optionsdelivr.com/qrcodegenerator or qrcode.kaywa.com or goqr.me offer various data generation options and varying levels of simplicity for
