Barcodes

What is most often used to indicate an incorrectly read bar code is an audible annunciator of some kind. A bell or tone or "uh-oh" sound alerts clerks that something read wrong.

In newer machines an error file is created that shows date and time plus till number /operator number where a scan fail has occurred . This can be used if there is a security request logged against the operation

A Barcode Recorder is used to read barcodes and store the information found in the code. The barcode recorder can be used for taking inventory in a store, checking out books from a library, to make a purchase from a store, for tracking shipments, and many other things.

A one million dollar barcode would likely look similar to any standard barcode, but it would carry a unique identifier that corresponds to the high value of the item it represents. Visually, it would consist of a series of black bars and white spaces arranged in a specific pattern. The barcode could also include additional security features, such as holograms or QR codes, to prevent counterfeiting. Ultimately, its appearance is less about the design and more about the value and security it signifies.

There are many ways bar codes have improved society. What is arguably the best example is the use of bar codes and scanners at store checkout counters to quickly and accurately price items to speed checkout.

G10 is probably a misnomer as there is an acronym which when pronounced sounds like G-TEN

GTIN = Global Trade Identification Number

It is not itself a barcode but an identification number that can be encoded in different barcode formats. UPC encodes a 12 digit number (GTIN-12) for example.

I'm sorry, but I don't have access to specific production dates for individual products, including Country Choice Cider with the barcode 50278767396. To find this information, you may need to check the packaging directly or contact the manufacturer for details.

There was no Apollo 18, the final mission of the Apollo program was A17. Apollo 18 is simply an urban legend and a movie, both of which are fictional.

The first product to have a bar code included was a packet of Wrigley's Gum.

I am writing a barcode scanner system.

First, I print barcodes like QR Code and Data Matrix on paper. Then scan these barcodes with a hardware barcode scanner. This scanner must read the barcode and verify its validity. Some organizers may want to verify ticket validity offline or online..

Some questions:

-Do I need a windows based app (so do something with windows forms?)?

- the scanned data from the scanner is sent to a PC...can I with VB.NET receive that data and pass it to an online app/server to verify the validity realtime?

- any other things I should consider?

Basically I want to avoid installing client software, is it possible?

For US mail. bar codes are scanned on packages to expedite delivery.

Bar code scanners can definitely be bought online. Some websites specialize in selling these scanners. They cost anywhere from 40 dollars to over 600 dollars.

You can purchase printers that print bar codes from several different places. Mainly the best place to get a good deal on these is to purchase one online.

"Bar Code scanners are available to the public. In fact, a bar code scanner application is standard fare on smart phones or phones with a camera and internet connection, and often come pre-installed."

Yes. The standard generated black and white code can be modified with the addition of colors and change in the actual structure of the code. For instance, the square-cornered edges can be rounded and curved. Colors can be added to various parts of the code. The background can be changed from white to include other colors or designs.

Most of these modifications require skill in using a program like Photoshop or Corel. It also requires careful testing as QR code readers will not be able to read codes that are beyond the limits of the reader software. A number of readers should be used for testing.

There are companies that will, for a fee, customize QR codes. This may include adding business logos or other specific designs. Other sources will allow you to purchase a pre-designed code style and they will both generate your website code and incorporate that code into the design you chose.
