Masking paper

Part of the adhesive bond which carries the self-adhesive material. Silicon is usually applied as a barrier layer so that the label can be removed from the base more easily.

Master data

Master data refers to a static part of the files managed in the warehouse management system. This data is not changed by processes in the warehouse and is therefore called static. It is subject to its own management functions within the master data management. These functions affect the input of new sets, modifications to existing and output of all or part of the data stock. Master data is required for items, loading aids, storage areas, employees, equipment etc. in warehouse management.

Matrix/matrix waste

Unused upper material, including the adhesive in a self-adhesive construction, which surrounds the cut-out label is usually removed once the label has been printed and cut out to allow the labels to be dispensed automatically.

Memory card

A reprogrammable transponder or transponder with read/writeability, often the size of a credit card

Metallised/aluminium vaporised films/papers

Plastic films or papers which have been given a very thin metal/aluminium layer on one side using a vacuum vaporisation process.


Part of the RFID system which connects the reading device to the back end.


Merchandise information system

Mobile data terminal (MDT)

Data terminal in which the data captured is saved locally and then transmitted to a base station in a batch. In contrast to a wireless terminal, an MDT works offline rather than online.


The thinnest element in a barcode is called a module. Wide bars or spaces are calculated as multiples of the module.

Module width X

Gives the width of the thinnest element e.g.: X = 0.33 mm.


A multiplexer is used to operate multiple antennas on one RFID reader. A sequence can be set in which the antennas are activated and switched off again. In general, two opposite antennas are activated. Using a multiplexer prevents antennas from disrupting each other and reduces costs for the RFID readers needed to cover the field without multiplexers. This allows the user to reduce the costs of the RFID system.
