Abstract

The invention discloses a card reader based on RF radio frequency communication. The card reader comprises a processor, a crystal oscillation circuit, a radio frequency transmit-receive circuit, a signal generation circuit, an antenna, a power supply module and an SAM card. The processor is respectively connected with the crystal oscillation circuit, the radio frequency transmit-receive circuit and the SAM card. The radio frequency transmit-receive circuit is respectively connected with the signal generation circuit, the antenna and the power supply module. The radio frequency transmit-receive circuit is used for modulating and demodulating radio frequency signals of which the frequency is 13.56MHz. The signal generation circuit outputs carrier signals of which the frequency is 13.56MHz to the radio frequency transmit-receive circuit. The SAM card can provide a security mechanism. The security requirement is met and the circuit structure of the card reader is simplified so that use is facilitated for users, and production cost is also greatly reduced. The card reader based on RF radio frequency communication is generally used for reading the data stored in an electronic tag of the specific signal frequency.

Description

technical field [0001] The invention relates to card reader equipment in the communication field, in particular to a card reader based on RF radio frequency communication. Background technique [0002] In recent years, short-distance wireless communication technology has developed rapidly. Among them, radio frequency identification technology is widely used in various fields, such as identification, traffic cards, etc. Among them, radio frequency communication technology based on a signal frequency of 13.56MHz is the most widely used. However, the card reader for this signal frequency in the existing design has complex structure and functions, and the cost is relatively high, so it is not suitable for low-end customer groups with a single purpose. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a card reader based on radio frequency communication with a signal frequency of 13.56 MHz, which has a simple principle ...
