This invention relates to a method and reader system for reading a mechanically variable display, particularly those provided with a meter, as well as to a metering system and a meter for measuring a commodity. In particular, the invention relates to a method and reader system for electronically reading a variable display comprising one or more mechanically variable display elements variably displaying one or more machine readable code/s which involves receiving reading data from an optical reader device, the reading data comprising at least an electrical signal, or information associated therewith, associated with at least one machine readable code read by the optical reader device; and processing the received reading data to determine a reading or character string associated displayed by, or associated with, the variable display. |

1. A method for electronically reading a variable display comprising mechanically variable display elements variably providing or displaying machine readable codes, the method comprising:
receiving reading data from a reader device, the reading data comprising an electrical signal, or information associated therewith, associated with machine readable codes read by the reader device, wherein the machine readable codes are provided or displayed by all or a majority of display elements of the variable display, and wherein the machine readable codes are non-alphanumeric machine readable codes which correspond to numeric or alphanumeric values or characters either associated with the display elements, or displayed by the display elements in addition to the machine readable codes; and processing the received reading data to determine each character associated with the machine readable code provided or displayed by each display element, and concatenating the determined characters in an order corresponding to positions of the corresponding variable display elements on the variable display thereby to determine a reading or character string displayed by, or associated with, the variable display, and determining a value associated with the concatenated determined characters. |
