Abstract

The invention relates to a key loading method and a key loading system for a password keyboard. The password keyboard comprises a plurality of key storage spaces which are in a linear structure; the keys are divided into a plurality of groups; each group of keys comprise one or more keys; and the keys in each group of keys are constructed in layered manner. According to the key loading method and the key loading system, disclosed by the invention, the plurality of keys are supported; application programs of a plurality of password keyboards can be expanded and are simultaneously stored in the password keyboards at a flexible key storage level and a support for the plurality of groups of keys, and thus the flexibility of the password keyboard to the application support is improved and the service efficiency of the password keyboard is improved.

Description

technical field [0001] The invention relates to a key loading method and system, in particular to a key loading method and system for a password keyboard of a deposit / cash machine. Background technique [0002] With the development of society, automatic deposit / cash machines are increasingly used in the financial industry. Since ATMs are mostly placed outdoors, safety measures for ATMs have always been the focus of research, especially PIN pads. In the prior art, the PIN pad usually adopts a transaction master key. Therefore, the PIN pad can only support one application program injected into the key party. When the application program needs other keys, the PIN pad needs to be replaced. Not only wasting hardware, but also increased the work, at the same time, greatly limited the extension of the password keyboard application program. Contents of the invention [0003] The technical problem solved by the invention is to construct a key loading method and system of a ci...
