Barcode Technology - Code 128A Barcode               Hide the description

Code 128A: encodes numbers 0-9, uppercase A-Z, and control characters (ASCII 1-31,127), and special characters.

Code 128 barcode has three code sets (Code 128A, Code 128B, Code 128C).

Code 128 is a high-density linear barcode symbology. It is used for alphanumeric or numeric-only barcodes. It can

encode all 128 characters of ASCII and, by use of an extension symbol (FNC4), the Latin-1 characters defined in ISO/IEC 8859-1.[citation needed]. It generally results in more compact barcodes compared to other methods like Code 39, especially when the texts contain mostly digits.

Code 128 Auto can encode the complete ASCII-character set. It will auto switch in all 3 character sets of Code 128:

Code 128A: (Set A) encodes numbers 0-9, uppercase A-Z, and control characters, and special characters.

ASCII characters 00 to 95 (09, AZ and control codes), special characters, and FNC 14

Code 128B: (Set B) encodes numbers 0-9, uppercase A-Z, lowercase a-z, and special characters.

ASCII characters 32 to 127 (09, AZ, az), special characters, and FNC 14

Code 128C: (Set C) encodes numeric data and FNC1, specially optimized for numbers.

0099 (encodes two digits with a single code point) and FNC1

Code 128A is one of the many barcode formats currently in use.

A Barcode is a method of representing data in a visual, machine-readable form.

The barcode formats has two categories:

One-dimensional (1D) --- Barcodes represented data by varying the widths and spacings of parallel lines.

Two-dimensional (2D) --- Using rectangles, dots, hexagons and other geometric patterns to represented data.

Code 128A is 1D barcode.

Code 128 is a very effective, high-density symbology which permits the encoding of alphanumeric data. It includesverification protection both via a checksum digit and byte parity checking. This symbology has been widely implemented in many applications where a relatively large amount of data must be encoded in a relatively small amount of space.

Code 128A is variable with no fixed length.

 

For the end user, Code 128 barcodes may be generated by either an outside application to create an image of the

barcode, or by a font-based barcode solution. Either solution requires the use of an application or an application add in to calculate the check digit and create the barcode.

Check digit:

The check digit is a weighted modulo-103 checksum. It is calculated by summing the start code 'value' to the products of each symbol's 'value' multiplied by its position in the barcode string. The start symbol and first encoded symbol are in position 1. The sum of the products is then reduced modulo 103. The remainder is then converted back to one of the 103 non-delimiter symbols (following the instructions given below) and appended to the barcode, immediately before the stop symbol.
For example, in the following table, the code 128 variant A checksum value is calculated for the alphanumeric string PJJ123C:

==================================================================================
Code                   Value    Position     Value * Position

---------------------------------------------------------------------------------------------
Start Code A       103        1                103
                 P        48          1                 48
                 J        42          2                 84
                 J        42          3                 126
                 1        17          4                 68
                 2        18          5                 90
                 3        19          6                 114
                 C        35          7                 245
                 Sum                                   878
                 Remainder mod 103           54

===================================================================================
For the purpose of computing the check symbol, the shift and code-switch symbols are treated the same as any other symbol in the bar code. The checksum is computed over the symbol values, without regard for which code set is active at the time. For instance the code set C value "33" and the code set B value "A" are both considered to be a Code 128 value of 33, and the check digit is computed based on the value of 33 times the symbol's position within the barcode.

Barcode length optimization:

Code set C (Code 128C) uses one code symbol to represent two digits, so when the text contains just digits it will generally result in shorter barcodes. However, when the string contains only a few digits or it's mixed with non-digit character, it does not always produce a more compact code than code sets A or B.

Human Readable:

Most barcodes display their corresponding values below them, which makes it possible to human read and manually  enter the barcode values into the equivalent system when the barcode label is worn out and cannot be read by the barcode scanner.

Advantages:

If you want to reduce costs and save time, using barcodes is a good choice. Whether you are a company or a non-commercial organization, to improve efficiency and reduce overhead, barcodes are a valuable and viable option, which is economical and reliable.

The barcode system provide better data. Because a barcode can store various information such as inventory and pricing, especially when using QR Code, it can store thousands of characters, so the data stored in the barcode can be quickly obtained by the barcode reader, this fast turnaround ensures that time is not wasted on data entry or retrieval. In addition, the barcode can be customized to include other relevant information as needed. They provide fast and reliable data for various applications.

When barcodes are used in management information systems, they can promote better decision-making. Because data is obtained quickly and accurately, you can quickly obtain a full range of information for the entire company or organization, so it is possible to make more informed decisions. Better decisions can ultimately save time and money.
