| Abstract: | According to contaetless reader of 13.56MHz in power and volume problems, the paper puts forward a low-power high security research model.The model used MSP430F2272 for control chip and RC522 for RF chip, In order to ensure stable and anti-interference ability, communication distance can achieve 10mm premise, can make the system effectively reduce power consumption and volume. The experiment results show that the system, power supply suitable for 3.3V MF RC522 power requirements, realizes the perfect combination of low power consumption. |
