Let&#8217;s learn what they are, why and where we use them and how to use them.<\/p>\n\n\n\n<h3 class=\"has-black-color has-text-color wp-block-heading\" id=\"h-qr-codes-what-are-they\">QR Codes &#8211; What Are They?<\/h3>\n\n\n\n<p class=\"has-black-color has-text-color\">QR is an abbrevation for &#8220;quick response.&#8221;  Basically, the QR Code is a two-dimentional bar code.  The code was developed in 1994 by Masahiro Hara and his team of engineers at <strong><a href=\"https:\/\/www.denso-wave.com\/en\/technology\/vol1.html\" target=\"_blank\" rel=\"noreferrer noopener\">Denso-Wave<\/a><\/strong>.  Once created, QR Codes were used primarily in manufacturing and warehousing.  While there were some other businesses using them, the QR Code explosion didn&#8217;t really happen until Covid-19.  Because of the Pandemic, we became a no-touch society and QR Codes became a hit!<\/p>\n\n\n\n<h3 class=\"has-text-align-left has-black-color has-text-color wp-block-heading\" id=\"h-where-we-use-them\">Where We Use Them<\/h3>\n\n\n\n<p class=\"has-black-color has-text-color\">If you can print or paint on something, you can almost always use a QR Code.  They are used on printed programs, bulletins, posters and more.  They appear on windows, on signs and even on automobles and computers.  When you gas up your vehicle, one of them often appears on the pump.  <\/p>\n\n\n\n<p class=\"has-black-color has-text-color\">The QR codes can link to PDF files, websites, coupons, Social Media channels, videos, events, Facebook likes, individual accounts (e.g., Sam&#8217;s Club, Walmart, BJs, etc.) and more.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color\">Do you have to be in business to create one or more of these?  Absolutely not.  Perhaps you belong to a club or maybe you&#8217;re going to have a special event.  You could hand out flyers with QR Codes on them!<\/p>\n\n\n\n<h3 class=\"has-black-color has-text-color wp-block-heading\" id=\"h-qr-codes-how-you-use-them\">QR Codes &#8211; How You Use Them<\/h3>\n\n\n\n<p class=\"has-black-color has-text-color\">In industry situations, special readers are used to take advantage of QR Codes.  For the average person, however, you just need a smart phone or a tablet connected to the Internet.  Until a few years ago, you had to have a special app to read the codes.  Now, however, almost all modern smart phones and tablets will interpret the coding just by using the device&#8217;s camera.  (Note: you may need to grant permission to use your camera the first time you go to scan one of these codes.)<\/p>\n\n\n\n<p class=\"has-black-color has-text-color\">There are, however, some differences between how an Android and an Apple product treat certain QR Codes.  For instance, if I post a PDF file to the web and scan its code with my iPhone or iPad, the PDF will open directly on my device.  On an Android, however, I would need to download the PDF and then open it.  <\/p>\n\n\n\n<h3 class=\"has-black-color has-text-color wp-block-heading\" id=\"h-what-it-looks-like-on-your-device\">What It Looks Like On Your Device<\/h3>\n\n\n\n<figure class=\"wp-block-gallery alignwide has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"741\" height=\"1024\" data-id=\"6883\" src=\"https:\/\/www.4kcc.com\/blog\/wp-content\/uploads\/2022\/05\/IMG_1318-741x1024.jpeg\" alt=\"Scanning a code on an Apple product\" class=\"wp-image-6883\" srcset=\"https:\/\/www.4kcc.com\/blog\/wp-content\/uploads\/2022\/05\/IMG_1318-741x1024.jpeg 741w, https:\/\/www.4kcc.com\/blog\/wp-content\/uploads\/2022\/05\/IMG_1318-600x830.jpeg 600w, https:\/\/www.4kcc.com\/blog\/wp-content\/uploads\/2022\/05\/IMG_1318-217x300.jpeg 217w, https:\/\/www.4kcc.com\/blog\/wp-content\/uploads\/2022\/05\/IMG_1318-768x1062.jpeg 768w, https:\/\/www.4kcc.com\/blog\/wp-content\/uploads\/2022\/05\/IMG_1318-1111x1536.jpeg 1111w, https:\/\/www.4kcc.com\/blog\/wp-content\/uploads\/2022\/05\/IMG_1318.jpeg 1252w\" sizes=\"auto, (max-width: 741px) 100vw, 741px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"719\" height=\"911\" data-id=\"6884\" src=\"https:\/\/www.4kcc.com\/blog\/wp-content\/uploads\/2022\/05\/android_pdf_scan.jpg\" alt=\"Scanning a code on an Android\" class=\"wp-image-6884\" srcset=\"https:\/\/www.4kcc.com\/blog\/wp-content\/uploads\/2022\/05\/android_pdf_scan.jpg 719w, https:\/\/www.4kcc.com\/blog\/wp-content\/uploads\/2022\/05\/android_pdf_scan-600x760.jpg 600w, https:\/\/www.4kcc.com\/blog\/wp-content\/uploads\/2022\/05\/android_pdf_scan-237x300.jpg 237w\" sizes=\"auto, (max-width: 719px) 100vw, 719px\" \/><\/figure>\n<figcaption class=\"blocks-gallery-caption\">On the left, an iPhone scan.
