    • A device and method for validating a ticket having magnetic ink printed on at least one side of a ticket. The ink is magnetized to create a magnetic signal in the magnetic ink and thereafter a media reader sensor spaced from the ticket is used to verify the existence of a magnetic signal. The magnetic signal is comparable to pre-existing data to determine a match and/or validate tickets having a match. An optical reader can be used to obtain additional data stored in the form of bar codes or patterns on the printed magnetric ink. The optical signal is comparable to pre-existing data to determine a match and/or validate tickets having a match. Preferred comparators for magnetic and optical matching are microprocessors and preferred media reader sensors for magnetic readers are anisotropic ma netoresistive sensors.
    • 一种用于验证在机票的至少一侧上印刷有磁性墨水的机票的装置和方法。 墨水被磁化以在磁性墨水中产生磁信号,然后使用与票证间隔开的介质读取器传感器来验证磁信号的存在。 磁信号与预先存在的数据相当,以确定具有匹配的匹配和/或验证票据。 可以使用光学读取器来获得以打印的磁性墨水上的条形码或图案形式存储的附加数据。 光信号与预先存在的数据相当,以确定具有匹配的匹配和/或验证票据。 用于磁和光匹配的优选比较器是微处理器,并且用于磁读取器的优选介质读取器传感器是各向异性的电阻传感器。
