Industrial 2 of 5 codes mentioned above have spaces of fixed width, while Interleaved 2 of 5 codes do not have fixed-width spaces — allowing both the bar and space widths to be used in encoding information. Standard 2 of 5: Yet another variation of the Industrial 2 of 5 code, the Standard 2 of 5 code also has spaces of fixed width.
Codabar: Codabar barcodes are used in blood banks, in libraries, in photo labs, and by Federal Express. Code These are high-density barcodes most frequently used to label equipment in the telecommunications industry. Code 11 is also known as USD There are also several alpha-numeric variations symbologies : Plessey Code: Used to mark grocery store shelves, the Plessey code has several variations including the MSI, Anker, and Telxon barcodes.
The MSI barcode is still used today in the U. It can encode digits from 0 to 9 and the letters A through F. Code 39 Code 3 of 9 : Code 39 symbology is used for item identification, for inventory management purposes, and for tracking shipments. Code A more compact version of Code 39, Code is preferred due to its compact size for the same applications. Department of Defense. Applications for 1D Barcodes In addition to point-of-sale applications, 1D barcodes are also used for labeling raw materials and inventory management , providing a way to monitor inventory levels with less need for hands-on human intervention and less room for human error.
Advantages of 1D Barcodes Barcodes are widely utilized due to a few distinct advantages: They are relatively inexpensive.
They allow for more accurate inventory management compared to manual inventory methods. They enable speedy, efficient operations. What is a QR Code? Applications for QR Codes Thanks to their ability to store various types of information, QR codes are used for a variety of applications. While QR codes gained recognition due to their increasingly widespread use in marketing and consumer-facing applications, they can also be useful in industrial applications , such as: Operational instructions: QR codes can be used to convey operating instructions, procedures, and other information necessary for operating heavy equipment.
Facilities management: They can be used to document schematics and other instructions for plumbing, wiring systems, and alarm systems, providing an easy way to communicate these details to contractors or maintenance workers. Maintenance and repairs: QR codes may be used to submit requests for maintenance service or as a way to easily document that routine maintenance has been performed, creating a complete audit trail of service and repair records.
Regulatory compliance: In industrial applications, equipment and machinery often requires periodic inspection, regular maintenance, and permits or licenses to comply with regulatory requirements. QR codes can be utilized to store this information and make it readily accessible. Advantages of QR Codes 2D barcodes , as a whole, are considered more secure, as the information they store is easily encrypted and allows for less room for error. Readability: Analyzing Potential Readability Issues QR codes may be considered easier to scan compared to 1D barcodes, as they can be scanned in any direction, whereas 1D barcodes have to be scanned from the proper angle.
That said, readability issues the ability of a barcode scanner to scan and decode data in a barcode are a concern with both 1D and 2D barcodes, and they often suffer from similar technical and environmental variables, such as: Low contrast: Barcode scanners both linear scanners and imagers require high contrast in order to scan a barcode or QR code accurately.
You've probably noticed a square barcode pasted to a graffitied light pole or on the back of a business card. That pixelated code, shaped in a square, is called a QR code.
They help you download apps, give you contactless access to a restaurant's menu, can be found on marketing billboards, and on websites or social media to promote items and deals. Despite being a mids invention, the QR code didn't gain real momentum until the era of smartphones.
Mobile devices allowed the digital mark to be used in more dynamic and diverse ways, making it an easy — and in the era of a pandemic, contactless — way to connect to and share information.
Invented in by Masahiro Hara, chief engineer of Denso Wave , a Japanese company and subsidiary of Toyota, the QR code was initially used to track vehicles and parts as they moved through the manufacturing process. Short for Quick Response, QR codes are a type of barcode easily readable with digital devices like smartphones.
They store information as a series of pixels in a square grid that can be read in two directions — top to bottom and right to left — unlike standard barcodes that can only be read top to bottom. QR codes can store about 7, digits or around 4, characters, including punctuation and special characters. It can also encode information like phone numbers or internet addresses. The arrangement of each QR code varies depending on the information it contains, and that changes the arrangement of its black modules.
When creating a code, you can add data to it, though it increases the code's structure and makes it more complex, and even personalize them. While the software used to generate QR codes doesn't collect personal information from users, the location and time of a scan, the number of times a code is scanned, and the operating system of the device that performed the scan are all available to the code's creators. QR codes vary in design depending on the encoded data and function, and can be categorized primarily in two ways: static and dynamic.
A static QR code cannot be modified once it has been created. This is ideal for creating QR codes in mass for an event. But a QR code is read in two directions — top to bottom and right to left. This allows it to house significantly more data. The data stored in a QR code can include website URLs, phone numbers, or up to 4, characters of text. QR codes can also be used to:. The development team behind the QR code wanted to make the code easy to scan so that operatives did not waste time getting it at the right angle.
They also wanted it to have a distinctive design to make it easy to identify. This led them to choose the iconic square shape that is still used today. Denso Wave made their QR code publicly available and declared they would not exercise their patent rights. This meant anyone could make and use QR codes. Initial uptake of the idea was slow; however, in , the first mobile phones containing built-in QR readers were marketed in Japan. The use of smartphones led to an increase in the number of companies using QR codes.
In , Denso Wave continued to improve on their original design. Their new QR codes include traceability, brand protection, and anti-forgery measures. There are many new uses for the QR code, from transferring payments to determining objects' positions within augmented reality. Most smartphones have built-in QR scanners, which are sometimes built in the camera. A QR scanner is simply a way to scan QR codes.
Some tablets, such as the Apple iPad, have QR readers built into their cameras. Some older devices may require a particular app to read QR codes — these apps are readily available on the Apple App Store and Google Play.
Attackers can embed malicious URLs containing custom malware into a QR code which could then exfiltrate data from a mobile device when scanned.
It is also possible to embed a malicious URL into a QR code that directs to a phishing site, where unsuspecting users could disclose personal or financial information. Because humans cannot read QR codes, it is easy for attackers to alter a QR code to point to an alternative resource without being detected.
Aside from opening a website, these actions can include adding contacts or composing emails. This element of surprise can make QR code security threats especially problematic. A typical attack involves placing malicious QR codes in public, sometimes covering up legitimate QR codes. Unsuspecting users who scan the code are taken to a malicious web page which could host an exploit kit, leading to device compromise or a spoofed login page to steal user credentials.
Some websites do drive-by downloads , so simply visiting the site can initiate a malicious software download. Mobile devices, in general, tend to be less secure than computers or laptops.
Since QR codes are used on mobile devices, this increases the potential risks. QR code-generating software does not collect personally identifiable information. Hackers can create malicious QR codes which send users to fake websites that capture their personal data such as login credentials or even track their geolocation on their phone. This QR code can be scanned with the Google Authenticator app on your smartphone and your smartphone will automatically fill in your authenticator information.
This is much more convenient than manually typing in an authentication code and checking to see if it was typed correctly. In this case, a QR code is being used to allow a computer and smartphone to communicate with each other. QR codes can also be used to log into websites. QR codes do have their uses.
To use a QR code, someone has to have a dedicated barcode reader app on their phone, launch the app, and scan the barcode to visit the website. In the same time, they could just have typed a short URL for the website or performed a Google search for it. To make matters worse, scanning a QR code can be complicated by the need to capture it at the appropriate angle, with enough light for the camera to see it, and without camera movement.
Just open your app, start a scan, point it at a QR code, and the app should recognize and take action based on the QR code — generally opening its website in your browser. QR codes actually have some security problems — it would be easy for an attacker to print a QR code with a malicious URL on a sticker and affix it over a QR code in a high-traffic area. A QR code redirects you to an URL in your mobile browser, so it would be possible to take the user to a phishing site or a page that exploited a vulnerability in their mobile operating system.
