Title:
ID CODE READER FOR TIME CARD
Document Type and Number:
Japanese Patent JP3137807
Kind Code:
B2
Abstract:
PURPOSE: To deduce a real ID code by respectively retrieving the use conditions of two read ID codes when the two ID codes are simultaneously read from one time-card, therefore the real ID code can not be known.
CONSTITUTION: Since a code sensor reads a mark M described in a data column S of a time-card T, a date numeral describing the mark M is defined as the ID code of a card user and on the other hand, when the code sensor simultaneously reads two marks M, namely, two ID codes from one time card T and one ID code is already used, the other ID code is qualified as the real ID code but when both of IC codes are not used yet, both these ID codes are temporarily stored in a memory. When any one ID code is used during holding, the other remaining ID code is qualified as the real ID code.
