The present technology relates to a signal processing device and method, and a program that enable a communication distance to be extended while suppressing a signal delay in non-contact communication. The signal processing device filters a signal received from a reader/writer via a first antenna and transmits the filtered signal to a card, which is a non-contact communication device, via a second antenna. Further, the signal processing device filters the signal received from the card via the second antenna and transmits the filtered signal to the reader/writer via the first antenna. The present technology can be applied to a communication system that uses non-contact communication.
