Definitions
- the present invention in accordance with the title of the specification, relates to a coding terminal, which, connected to a sales terminal or any other device having an asynchronous interface, and the appropriate software, allows various coding functions to be carried out with a guarantee of confidentiality for the data introduced by the user via the keypad provided.
- the coding terminal proposed by the invention solves the mentioned problems through the use of a hybrid circuit which combines adequate physical security and reasonable cost, avoiding at the same time the problem of dependence on sole supplier.
- the hybrid circuit includes a microcontroller, RAM memory and PROM memory, and the necessary interface circuits for control of keypad and display.
- a UART included in the microcontroller is used for obtaining a series interface through which the device is communicated to other terminals.
- liquid crystal display which is optionally included, it likewise allows the user to "monitor" the operations carried out. This is of special interest in sales operations, where the client can see the amount keyed in.
- Security of the system lies in the fact that user's confidential data travels in a coded manner between the sales terminal and the coding terminal.
- the design of the device described allows the use of a compact, light and ergonomic terminal, easy to use with only one hand, and intelligent, since it comprises a microprocessor, which makes it a programmable system, capable of carrying out complex operations of communication, coding and treatment of peripherals, with the possibility of storing codes in a non-volatile PROM and/or RAM memory with battery backup.
- It may be connected to any system through an RS-232 interface, all that is required as a hardware interface being a simple circuit for changing signal levels.
- the coding terminal being described is comprised by a hybrid circuit including a microcontroller 80031, RAM memory and EPROM memory, and the necessary interface circuits for controlling keypad 2 and display 3.
- the microcontroller in turn includes a UART which is used for obtaining the series interface by means of which the system is communicated to other terminals.
- a flexible cable 4 and a connector 5 For connection to the terminal, it is provided with a flexible cable 4 and a connector 5.
