The code height is not dependent on narrow bar or ratio and tends, therefore, to be defined by individual applications. For example, the Automotive Industry Action Group (AIAG) defines a set of labeling standards for marking inter-company shipments within the industry; these labels use Code 39. Take the value (0 through 42) of each character in the bar code. It is also used for transferring data between companies. this content
Sum the value of each of the values of each of the characters described in step 1. In IDAutomation Code 39 barcode fonts, the exclamation and parentheses characters are also used as start/stop characters to avoid these problems and provide additional functionality. CODE 39 ENCODING TABLE This table indicates how to encode each digit of a Code 39 bar code. There is a space between each character. Get More Information

In other words, if a code 39 bar code has additional bar codes to follow, it must start with a space-if the bar code is the last bar code in the Code 39 Font Most barcode scanners have the ability to read Code 39 barcodes by default, such as the IDAutomation USB Barcode Scanner. The following standards based on the 3 of 9 barcode require MOD43 check digits: LOGMARS (Logistics Applications of Automated Marking and Reading Symbols) is a standard based on Code 39 used http://www.idautomation.com/barcode-faq/code-39/ WWNNNNWNN 110010101101 16 G NNNNNWWNW 101010011011 38 SPACE NWWNNNWNN 100110101101 17 H WNNNNWWNN 110101001101 39 $ NWNWNWNNN 100100100101 18 I NNWNNWWNN 101101001101 40 / NWNWNNNWN 100100101001 19 J NNNNWWWNN 101011001101 41
When the IDAutomation Code 39 Barcode Font is used, the parenthesis may be used as the start and stop characters to keep the asterisks from appearing in the text interpretation. Code 39 Windows 7 To calculate the optional checksum digit, follow the following steps. The START character (*): 100101101101. A few of the Barcode Integration Guides offered include the following: Access Android Apps Crystal Reports C++ C# .NET Excel FileMaker iOS Apps Open Office & Star Office Oracle Reports SQL
The barcode itself does not contain a check digit (in contrast to—for instance—Code 128), but it can be considered self-checking on the grounds that a single erroneously interpreted bar cannot generate Use the Symbol Encoded Fonts that encode the space character without a substitution character; Available in the latest version of the IDAutomation Code 39 Fonts. Code 39 Barcode Generator Here is how to do the checksum calculation: Take the value (0 through 42) of each character in the barcode excluding start and stop codes. Code 128 The two wide bars, out of five possible positions, encode a number between 1 and 10 using a two-out-of-five code with the following numeric equivalence: 1, 2, 4, 7, P.
Introduction Bar Code Uses Bar Code Structures Getting a Good Scan PostScript Imaging of Bar Codes Quality Checking UPC EAN ISBN Code 128 Code 39 ITF (Interleaved 2 of 5 ) news FileMaker Pro: Enter "*" & Field & "*" in a calculated field so that the asterisk is appended to the beginning and ending of the data from the source field. Legal Notices. When a barcode is scanned using keyboard emulation, the data scanned appears at the cursor as if it had been typed in from the keyboard. Code 39 Driver Error
Most barcode scanners recommended by IDAutomation perform keyboard emulation and receive power from the USB port, so that no external power supply is required. Code 39 Table The table below shows the character set and the bar/space pattern for the character. The asterisk is only used as a start and stop code. http://allsoftwarereviews.com/code-39/code-39-cd-rom.php Additionally, the check digit option in all Components and Applications calculates and includes the checksum automatically.
The asymmetry of the symbol allows the reader to determine the direction of the barcode being scanned. Code 39 Extended ENCODING THE SYMBOL Once the checksum digit has been calculated we know the entire message which must be encoded in the bars and spaces. Although a checksum character is optional, many standards require it.
Characters are separated by an inter-character gap which is the same width as a narrow bar. IDAutomation Code 39 Barcode Fonts may be created directly from the keyboard or used in a calculated field to dynamically produce multiple symbols in many applications, including Microsoft Word, Excel, FileMaker, Lotus Notes: A formula that places a return function (in extended39) between fields: "*" + DataField1 + "$M" + DataField2 + "*" Lotus Approach: Combine('*', DataField, '*') - Here is an Code 39 Vs Code 128 These integration options should be examined to determine whether to use barcode components, applications or fonts for the printing of barcodes.
Because there are only six letters in the Letters(+30) group (letters 30–35, or U–Z), the other four positions in this group (36–39) are used to represent three symbols (dash, period, space) Retrieved 2010-07-22. ^ "Adoption Notice: AIM/BC1 Uniform Symbology Specification". 1997-06-19. Type the stop character of "*" . http://allsoftwarereviews.com/code-39/code-39-xp.php The asterisks are encoded into the barcode, but their representation in the human readable text is optional.
The symbology of the Code 39 character set consists of barcode symbols representing numbers 0-9, upper-case letters A-Z, the space character and the following symbols: - . $ / + %. Divide the result by 43. Extended Code 39 gives the detailed specification showing how to encode the whole 128 ASCII character set using Code 39. The digit "8": enocded as 110100101101.

Code 39 can be read by just about every scanner on the market. Note that a barcode reader cannot automatically determine whether a barcode is encoded normally or in the extended set.
