PURPOSE:To enhance the safety of collation by collating the magnetic card, simultaneously reading the magnetic code, temporarily storing it, and setting and changing the collating code of the collating device. CONSTITUTION:To the collating device of a quest room, the address code classified by a class is set. To the magnetic card issued by the front desk, an address code 15, a data code 16, and a memory enable code 17 are recorded. The address code 15 is the same as the address code of the collating device of the designating room, and the data code 16 is classified by the quest. When the quest inserts the magnetic card into the collating device of the room, the address code 15 is collated, and coincident, and when a memory enable code 17 is detected 3, the data code 16 is read, stored 5 temporarily, a collating coincident signal is generated, the memory enable signal is deleted, and unlocked. As long as the card is correctly used, the coincidence of the collation of an address collating device 1 and a main collating device 6 simultaneously occurs, also unchanged after deleting the memory enable code, and unlocking can be executed over and over gain. By the constitution, the magnetic card collating device with a high safety can be obtained. |
