It used to be that only businesses with specialized scanners could use bar code technology. Now, tablets, smart phones and other consumer devices enable the ordinary person to easily scan bar codes and QR codes.
Most tablets are equipped with built-in cameras, and there are many bar code scanning tablet apps available that work with the camera to scan and decode bar codes.
The biggest advantage of tablet apps for scanning bar codes and QR codes is how easily they allow you to access digital information on your tablet. Unlike computers, which have regular keyboards, it is more challenging and time-consuming to type with a tablet.
Scanning bar codes and QR codes offers a more convenient way to access data on your tablet--simply point your built-in camera at the code. The tablet app then uses image processing techniques to decode the bar code or QR code. You can even use bar codes and QR codes to pass information from a tablet to another tablet or device by scanning a bar code from the screen.
Most products, such as grocery items, books, CDs, DVDs, have had bar codes for quite some time. The bar codes were primarily used by staff for tracking inventory and for checking out items at the point of sale.
Now, consumers are using bar code scanning apps to easily compare prices and reviews. Scanning grocery items allows consumers access to nutrition information, coupons and integration with shopping lists and grocery management software. Scanning personal property and receipts can also be used for insurance purposes or in personal finance software.
Thanks to tablets and smart phones, QR codes are also becoming more ubiquitous, especially in advertising via posters, post cards, catalogs, brochures as well as business cards. QR codes usually contain links to the website, calendar events, plain text, phone numbers and other contact information, making it simple for consumers to obtain more information about products, events and businesses.
Bar code scanning is increasingly used in enterprise applications, such as access control at gates, inventory reporting and asset tracking.
Here are a few of the best bar code scanning tablet apps on the market.
Barcode Scanner by the ZXing Team
Barcode Scanner is a tablet app by the ZXing Team and is one of the most popular bar code scanner apps for Android tablets. It has been installed around 50 million times and has an average rating of 4.3 in the Android market.
This barcode scanning tablet app is very easy to use. You can quickly scan 1D bar codes (such as UPC and EAN) as well as 2D formats (such as data matrix and QR codes) using your tablet.
Just use the camera on your tablet and place the code inside the rectangle, filling the entire viewfinder. The red line blinks as the app automatically focuses and analyzes the code. It beeps once it successfully scans the code and gives you options depending on the item.
Scanning a QR code shows the embedded information and allows you to choose between web search, share via email or share via SMS. Bar codes on books, CDs and other products connect to Google Product Search and Web Search, letting you view and compare prices and reviews.
Data Matrix and QR codes allow you to quickly add, update and share applications, bookmarks, geographic locations and website addresses. Scanning a contact gives you the option to merge to an existing contact or create a new one.
Aside from printed bar codes, you can also scan codes from the screen of your tablet, phone or computer. If a book is available in Google Books, you can even search for words in the book. Additional features include improved QR code decoding, contact sharing and Chinese translation.
The Barcode Scanner tablet app is very basic and does not have some of the features that other apps have, such as saving the history of your previous searches. But it is free, light-weight, fast and straightforward to use.
This bar code scanner tablet app is powered by ZXing (pronounced “zebra crossing”), an open-source library that processes multi-format 1D/2D bar code images using the built-in camera on mobile phones, tablets and other devices with or without communicating with a server.
