The patented solution from ACD together with modularity and standard interfaces make numerous attachable modules possible, including handles, RFID readers, printers, distance sensors, temperature modules, long-range scanners and different keyboard variants. The attachable modules mentioned here as well as other modules can also be adapted and implemented for specific customer requirements. Currently the keyboard variant M2Key16, temperature module M2Temperature for measuring core and surface temperature, logistics protective caps (M2 logistics protective caps) and an attachable handle (M2Griff5) are already optionally available. The individual mod-ules can be exchanged at any time without a tool using the insert/slide mechanism, thus allowing for highly efficient, economical and flexible work on the sales floor, in incoming goods or for various logistics applications. This new modularity, still unique on the market, makes it possible to configure customer-specific modules for all requirements.
