Electromagnetic or optic code i.e. promotional coupon code, processing method for use in e.g. store, involves emulating information by emulation unit connected to coin receptacle system, where unit can be laser scanner

摘要

The method involves reading and interpreting a new code by a coin receptacle system (43). Information e.g. article information, contained in the new code is displayed on a LCD display (41) e.g. LCD bistable display, under the form of a code e.g. bar code, readable by the system. The display presents black pixel reflectance two times lower than white pixel reflectance. The information is emulated by an emulation unit connected to the system, where the unit can be a laser scanner (42) or an inlet peripheral connected to the system. A client-card information is read by a reader (6). The display is composed of polarizers, a reflector i.e. retro-reflector, and liquid crystal cells. An independent claim is also included for a device comprising a reader and a LCD display.
