摘要： A device that can be used to check the authenticity of time-accounting systems and devices, and notably of time-accounting devices for reckoning periods of parking regulated by rules. The system is constituted by a plurality of boxes, each held by a distinct user, each box comprising computation means that determine at least two secret codes, the changing from one secret code to another being done substantially at one and the same instant for all of boxes and secret codes being identical for all of boxes substantially at the same instant to enable a checker to ascertain the authenticity of boxes, code-changing instant resulting from a secret computation.

摘要： Disclosed is a time-accounting system with optimized management. It can be applied, in particular, to accounting for paid or regulated parking times. The aim is to provide a system that enables a protected replacement of card, a management of fractions of parking units and a management of the change returned by the system, for uses in one of more local authority areas. The disclosed system is of the type comprising a memory card, a box for the reception of the card comprising a memory, wherein the storage capacity of the management memory of the box is limited to a maximum number of pre-determined parking units, and wherein transfer means provide for the transfer of the balance of parking units contained in the card towards the management memory of the box when the arithmetical total of the number of added-up units of the card balance and of the current content of the management memory of the box is smaller than or equal to the capacity of the management memory.
摘要翻译：公开了一种具有优化管理的时间计费系统。特别适用于支付或限制停车时间。目的是提供一种系统，可以保护更换卡，管理停车单元的分数，以及对系统返回的更改进行管理，以便在其他地方当局之一使用。所公开的系统的类型包括存储卡，用于接收包括存储器的卡的盒，其中盒的管理存储器的存储容量被限制为最大数量的预定停车单元，并且其中传送装置用于将包含在卡中的停车单元的余量转移到箱子的管理存储器，当卡的余额的累加单元数量和管理存储器的当前内容的算术总和框小于或等于管理存储器的容量。
