“Using RFID card you can lock or unlock your door.
The arduino based RFIDdoor lock system is secure and responsive as compared to other systems. Withthe use of arduino, it becomes much easy to design. Program a code and uploadit to arduino just like a plug and play device. It is simple and cost efficientproject and can be used as a basic access control mechanism. Their main advantageis contactless communication and RFID tags can work in any environmentalconditions. This is the reason RFID systems are more efficient.”
