Abstract

The invention discloses an ATM user keyboard with good safety. The keyboard comprises a keyboard panel, a key frame, a plurality of keys connected with the key frame, a silica gel gasket, a keyboard base plate, a keyboard mainboard and a keyboard rear cover, wherein the keyboard panel, the key frame, the keys, the silica gel gasket, the keyboard base plate, the keyboard mainboard and the keyboard rear cover are sequentially arranged from top to bottom, a plurality of button protrusions matched with the keys are arranged on the silica gel gasket, a controller is arranged on the keyboard mainboard, key contacts matched with the button protrusions respectively are arranged on the upper surface of the keyboard mainboard, the number of the button protrusions is the same as that of the key contacts, and conductive rubber columns which are used for penetrating through the keyboard base plate and are in contact with the key contacts when the keys are pressed down are arranged on the lower surfaces of the button protrusions. The keyboard has the advantages that the keyboard disassembling difficulty is large, the anti-attack capability is strong, and the data safety is good.

Description

technical field [0001] The invention relates to the technical field of bank automatic teller machine (ATM) safety protection, in particular to an ATM user keyboard with good security and strong ability to resist external attacks, and transaction information inside the keyboard is not easy to be stolen. Background technique [0002] The keyboard is the cardholder's user data input device installed on the ATM machine. The cardholder needs to enter the PIN code when using the ATM machine for transactions. The keyboard encrypts the PIN code and sends it to the background for verification. [0003] At present, the means of attacking the keyboard is mainly: installing a BUG circuit at the key of the keyboard panel of the keyboard. When the cardholder enters the PIN code through the keyboard, the BUG circuit records the plaintext of the PIN code; thereby stealing the transaction information inside the keyboard. [0004] Therefore, there is an urgent need to develop a keyboard with ...
