Description

hand-held type communicator of intelligence boot

Technical Field

The utility model relates to a financial security field especially relates to a hand-held type communicator of intelligence boot.

Background

At present, in financial institutions such as banking outlets, a trunk is generally used to store and transport important items such as cash received on the same day. The current popular mode is that a professional escort company sends the cash in the morning and receives the cash in the evening, takes out important articles such as cash from a national treasury or a similar storehouse of a financial institution in the morning, puts the important articles into a tail box and escorts the important articles to each financial network; and important articles such as cash and the like in the day are collected from each financial network at night and are transported back to the storeroom through the tail box. However, the delivery of the trunk involves three different institutions or personnel, namely a coffer, escort personnel and a network point, and certain soil is provided for safety problems.

in particular, in the conventional trunk system, the escort work is entrusted to a professional escort company, but in the transfer process, only signature confirmation between a bank teller and a bank teller is usually performed. Therefore, when warehousing in the evening, a manager cannot ensure whether the warehoused tail box is not operated after being collected on the network point, and when the warehoused tail box is taken out in the morning, each network point cannot confirm whether the received tail box is delivered to the warehouse and is not operated any more before opening the box. Namely, certain potential safety hazards exist in the process of handover and escort.

at present, an intelligent tail box is provided, and relevant operations of the intelligent tail box in the working process are recorded by arranging relevant chips and the like in the intelligent tail box. And when the trunk is handed over and managed, a receiving person manually triggers and activates the intelligent trunk, opens the trunk, inserts the data line, derives the information stored in the chip, and after the check is correct, the two parties carry out card swiping operation again and carry out hand-over after the confirmation. However, because the operation records and the alarm information such as errors stored in the chip of the intelligent tail box need to be unpacked first and then read by using a data line, such as a USB data line, the operation is complicated, errors are prone to occur, batch handover cannot be achieved, power consumption is high during handover triggering operation, and the like, so that the time for handover is delayed, and many units prefer to adopt a signature to confirm the simple but unsafe tail box handover method.

Thus, the prior art is yet to be improved and enhanced.
