Woodland had been thinking about the ways Morse code might be used to solve a problem his colleague Bernard Silver had presented to him. It all started in 1949 on a beach when Joseph Woodland, a mechanical engineer at Drexel University, drew a set of parallel lines in the sand that “represented a kind of ‘long form’ of dots and dashes” or Morse code. It is an ever changing story, as the technology behind the barcode is constantly evolving, and we discover ways to put more and more information into these “machine-readable” codes. The barcode has a long and interesting history from its initial development nearly 70 years ago through today. However, today barcodes come in many shapes and sizes and a wide range of designs and many can even be read by mobile phones and other devices. This vastly reduced the time it took to record such information and eliminated the potential for human data entry error.īarcodes started out with simple 1-dimensional designs, consisting of basic black lines that could only be read by specially designed barcode scanners. The lines and patterns on a barcode are actually representations of numbers and data and their development allowed basic information about a product to be easily read by an optical scanning device, a barcode scanner, and automatically entered into a computer system.

Barcode systems help businesses and organizations track products, prices, and stock levels for centralized management in a computer software system allowing for incredible increases in productivity and efficiency. What is a barcode ? A barcode is “A machine-readable code in the form of numbers and a pattern of parallel lines of varying widths, printed on and identifying a product.” But in truth a barcode is so much more. Yet barcodes play a crucial role in the effective and efficient operation of our economy, from small businesses to large multinational conglomerates.
–įortunately the limited special characters supported by “3 of 9” includes the dash (-) and slash (/) characters, so dates should barcode nicely.Every time we purchase something we interact with a barcode, but rarely do we give them much notice. So I usually use “ddMMMyy” or similar form, ie displaying the month portion in alpha form e.g. 1st of April or 4th of January unless I see one of the dates in the column (which could be many many rows long, most being off screen) meeting this condition. I usually avoid any date format with “dd/mm” in it because when people see a date is it “dd/mm” or “mm/dd” you’re looking at? Unless dd is > 12 I cannot be sure if it’s showing me e.g. You can of course choose whatever date format you wish.
So for this example, you would need to use the formula –īonus comment about displaying (or barcoding) dates: The way get the date format into the barcode is to use the TEXT function to show the date in the format you want. So when you assign a cell a value which you set the font to “FREE 3 of 9″ barcode font (or the extended version), the formula you would have is –įor dates, the above formula results in output like *43466* instead of **. If you don’t do this, the barcode won’t work. When using barcode (at least ‘3 of 9’) you need to start and end it with an asterisk (*) character. If A1 contains your date, either using a formula or merely entered as a date, and you need to choose a suitable format for excel to show that date.
You have to be careful which date format you pick for dates when using them in a barcode. I’ve been a bit verbose but hopefully it will explain what I think your question is asking. Just saw your query post from the beginning of the year (by accident than deliberate looking).
