The invention relates to a card reader system for a ticket-card of a parking lot and a panel device thereof. The system of the invention is characterized in that an RFID (radio frequency identification) technology is applied in the data annotation of the ticket-card and parking lot charging; the data is written in a chip of the RFID ticket-card by using a first antenna at a ticket-card inlet of the card reader and the data in the ticket-card is canceled by using a second antenna at a ticket-card outlet. Furthermore, the position data of the parking lot is written in the chip by using a third antenna in the parking lot, thereby facilitating a driver to find the car.
