KR20070118390A - Multi-function signature pad - Google Patents

Abstract

A wired electronic signature pad is provided to perform a role of a standalone payment terminal by installing an MSR or an RFID reader, and a communication module such as an RS(Recommended Standard)-232 or USB(Universal Serial Bus) module. A signature input part electronically receives a signature from a user. A PIN(Personal ID Number) pad receives personal information and a password from the user. A displayer displays inputted contents to the user. A card recognizer recognizes card information. A communication module communicates between the electronic signature pad and an information processing device. An encoding module encodes and compresses customer information received through the signature input part. The signature input part is a resistive film type touch panel for recognizing a touch position based on a voltage change according to a resistance change caused by a touch. The display part is a mono LCD(Liquid Crystal Display) screen placed under the touch panel.

Description

Wired compound digital signature {Multi-Function Signature Pad}

1 is a block diagram for a wired composite electronic signature according to the present invention;

Figure 2 is an MSR and S / W pin pad application image of the wired composite electronic signature according to the present invention

Figure 3 is a RFID and H / W pin pad application image of the wired composite electronic signature according to the present invention

The invention design of this device (composite digital signature) only served as a simple digital signature that allows the existing digital signature to be connected to a payment terminal, but when wired composite digital signature is used, payment can be completed in one device. As a result, more efficient and simple management is possible.

This device adopts MSR or RFID that can recognize the function of the digital signature, which was simply an accessory of a payment terminal, and it is equipped with RS232 or USB as a communication module. Could be done.

The composite digital signature includes a signature input unit for receiving a signature from a credit card user, an encryption module for encrypting signature data of a customer input through the signature input unit, and a communication module for transmitting the encrypted signature data to a credit card payment terminal; It consists of LCDs that can display signature data on the screen.

The electronic signer is connected to a PC, a laptop, a POS, a card payment terminal, etc. by means of a communication module of either RS232 or USB, and card recognition is performed through MSR or RFID recognition.

The communication module receives the authorization message from the van server and transmits the authorization message to the credit card payment terminal.

When the credit card payment terminal receives the authorization message, the authorization is completed, and after the authorization is completed, the seller requests a signature of the customer.

The signature input unit includes an LCD screen for inputting a signature using a touch pen.

The customer checks the amount of money displayed on the LCD and signs the data using the touch pen on the LCD screen provided in the signature input unit.

The encryption module generates two kinds of signature data for sending the signature data to the credit card payment terminal and the van server.

The signature data sent to the van server is encrypted using public key based encryption, and the signature data sent to the credit settlement terminal is encrypted based on private.

The communication module transmits the encrypted signature data to the credit card payment terminal, and receives a request for signature data from the credit card payment terminal.

This device has the effect of acting as a wired compound digital signature that can act as an independent payment terminal by attaching a card recognition unit to an existing digital signature as an accessory.

Claims (7)

Signature input unit input from digital signature user, pin pad to input personal information and password, screen display unit displaying contents to user, card recognizer to recognize card information, communication module for communication between digital signature device and information processing device Wired composite signature device including an encryption module for encrypting and compressing customer information data through an electronic signature device input unit. The method of claim 1, wherein the signature input unit and the screen display unit is coated with a resistive material on a glass or transparent plastic plate and covered with a polystyrene film thereon, the insulating rods are installed at regular intervals so that the two surfaces do not touch each other. When the contact is made, these two surfaces are connected to each other. At this time, the resistance value is changed and the voltage is also changed. The LCD screen is called the screen display unit, and the signature input unit and the screen display unit are combined into one. The complex digital signature device of claim 1, wherein the pin pad includes a device directly input by a user to eliminate the risk of exposure when the personal information and password are input. The complex digital signature device of claim 1, wherein the card reader that recognizes card information uses a magnetic stripe reader (MSR) that recognizes a magnetic card and an RFID that recognizes an IC card. The complex digital signature device of claim 1, wherein the communication module uses RS232 or USB. The composite digital signature device according to claim 5, wherein one of RS232 and USB is selected according to the specification of the information processing device. The complex digital signature device of claim 1, wherein the encryption module applies a self-compressing encryption algorithm such as DES and SEED.
