Two-dimensional barcodes (2D code) allow the information density per area to be significantly increased compared to a one-dimensional barcode (1D code). In a data matrix code, for example, the information is coded very compactly on a square or rectangular area as a pattern of dots. When a data matrix code is read, two different bar widths are no longer defined clearly in their order, as in a one-dimensional barcode, but rather the arrangement of the equal-sized dots within the frame and in the matrix grid. The dots are white or black dots connected to each other or round dots with gaps in between. Further 2D codes: QR code, semacode, bee tag, vericode and VS code.

RFID transponders with their own battery-operated power supply are called active transponders. There are transponders with replaceable batteries and ones whose batteries are in a sealed unit. The latter are called modular active transponders.

The ALOHA protocol is used to read information from RFID transponders. The reading device requests that all transponders in its range respond after a random time. If this results in collisions, the process is repeated until the information from all transponders has been read. The ALOHA protocol makes it possible to read off a lot of RFID labels reliably within a small space.

Either a thin aluminium foil laminated onto paper or a pure aluminium foil. Both are used as an upper material for self-adhesive products.

An antenna generally consists of a conductor which operates as a sending and receiving unit. It ensures that radio signals are transmitted between the sender or receiver and the medium (air).

If multiple transponders are addressed by a reading device at the same time, they answer at the same time, which can result in a data collision upon receipt. An anti-collision process is used to prevent this. In this, the transponders are addressed individually through a special process.

The information density of a barcode is given with the unit cpi (= characters pro inch). In Germany, the density is often expressed in 'space needed per character', i.e. in millimetres/character. To fit a barcode into the barcode box when there is little space, high density (i.e. as much information (characters) as possible per unit of length) is necessary. If the barcode is to be read from a distance, it is better to use a barcode with a lower density.

A batch is a compilation of multiple orders into an ordered mass (list) of orders. In contrast to interactive processing by programmes, the orders combined in a batch are processed without interruption by a single user input.

However, it cannot be assumed that code 128 can depict the entire ASCII character set directly with its character set. There are three distinct character sets, A, B, and C, which are used depending on the problem to be solved. These character sets can also be mixed. To represent the entire ASCII character set, start character A or B is needed in conjunction with a special character from code 128. Each character consists of 11 modules, divided into 3 bars and 3 spaces. The bars always consist of an even number of modules (even parity) and the spaces of an odd number of modules. The stop character is the exception and has 13 modules, consisting of 11 modules and a limiting bar with 2 modules.

By using a two-dimensional data matrix code (2D code), the information density per area can be increased significantly compared to one-dimensional barcodes (1D code). In a data matrix code, the information is coded very compactly in a square or rectangular areas as a grid of dots. When a data matrix code is read, two different bar widths are no longer defined clearly in their order, as in a one-dimensional barcode, but rather the arrangement of the equal-sized dots within the frame and in the matrix grid.

The dark part of a barcode

Most common codes are based on a binary principle with a number of thin and thick bars/spaces. The sequence of these thin and thick bars and spaces results in a specific numerical or even alphanumerical statement. It is read optically. The different reflections of the black bars and white spaces creates a train of pulses in the optical receiver which corresponds to this sequence of bars and spaces.

The barcode field consists of a barcode, two light quiet zones and a line of text. The barcode contains the encrypted information, consisting of coloured bars and non-coloured spaces. The quiet zone is located before and after the barcode and demarcates the object to be identified. The text line is under the barcode and depicts all the encrypted information in legible text
