A dual-LCD signature pad is provided to identify contents related to a signature by using a second LCD irrespective of scratches of a first LCD. A dual-LCD signature pad includes a signature input unit(2), an encryption module(3), and a communication module(4). The signature input unit includes a first LCD(10) and receives a signature. The encryption module receives signature data through the signature input unit and encrypts the received signature data. The communication module transmits the signature data encrypted by the encryption module, to a settlement terminal. A second LCD(20) outputs contents related to the signature and an advertising screen.
