摘要： A method for card-reading anti-collision with automatic frequency hopping is provided, which is used for a system in which a card reader simultaneously reads a plurality of cards in radio frequency identification technologies. The method comprises: both the card reader and the cards to be read are configured to have an automatic frequency-sweep function and a function of hopping from a current channel to another channel, and to store access addresses and transaction addresses; when the card reader is in a frequency-hopping card-seeking state, it is in an n-channel frequency-hopping working state, in which, the access address of each channel is the same, and the card reader reads the cards by means of hopping frequencies in a sequence iteratively through n channels. When the card reader detects that two or more cards collide, the card reader sends a command of random frequency hopping, making all the conflicting cards to hop to other channels randomly and to wait to access those channels. The beneficial effects of said method includes: it can quickly realize a card-reading anti-collision mechanism and improve the card-reading speed.
