Automated token system

摘要: An automated token system (particularly for toll roads) utilizing a which may be permanently magnetized and demagnetized. The is made of permanent magnetic materials such as barium ferrite plastic material, circular has uniform thickness. includes mechanism magnetically visually writing on the at an entrance to controlled area or road reader reading information exit. electromagnetic conditioner erases old head heads place data bits token. input from computer and/or shift register switches appropriate amplifiers signal heads. scanning takes transmits it computer. also gating determine side being read governs fed into. A binary-to-decimal converters are utilized in conjunction with display means give readable information. process involved this invention erasing any token, putting field through impressing form its entire thickness so that either handling further retrieving magnetic-sensitive scanner, deciding been read, feeding into desired order, information, converting decimal displaying manner.
