|Methods and techniques|
Barcodes (also known as bar codes) - this is a graphical representation of numbers, characters and letters with dark and light boxes. Their main task is to read information through a code reader.
Advantages of bar codes:
- enable automatic loading of information
- automatic identification of various types of products in storage, transport and commodity science
- accuracy of data recording
- positive impact on capital and inventory management
- speed of entering, reading and processing data
- improve documentation and billing
- streamlines the erase functions
- more effective transaction execution
- accelerated customer service
Types of barcodes
Division of codes by dimensionality:
- One-dimensional bar codes (linear, 1D) - information is contained on one line, usually in the form of bars.
- Two-dimensional two bar codes - information stored in several lines, one below the other.
- Barcodes Two-dimensional matrix - the information is written on the surface of the package in a form other than lines.
- Complex barcodes - a mix of one-dimensional and two-dimensional codes.
- Three-dimensional barcodes - extruded one-dimensional codes. Their depth is used to read them.
Breakdown by stroke width:
- Codes with one stroke width
- Codes with two line widths
- Codes with many strokes widths (modular)
Breakdown by type of coded symbols:
- Numeric - only digits in the decimal system are coded
- Alphanumeric - the digits and other characters of the ASCII code are encoded, sometimes also characters appearing in some alphabets
Breakdown by code continuity (not applicable to matrix codes):
- Continuous codes - there are no gaps between coded characters
- Discrete codes - there are spaces between coded characters
Breakdown by number of coded characters:
- Codes with a strictly defined number of coded characters (fixed length)
- Codes with a different number of coded characters (variable length)
Breakdown according to the adopted method of verification of read data:
- Self-check codes - some error checking procedures are implemented in the code construction
- Codes with a control character (eg with a check digit)
- Self-check codes that contain an additional check mark
