This page describes the construction of an RFID reader using only an Arduino (Nano 3.0 was tested, but others may work), a hand-wound wire coil, and some assorted low cost common components. Credits The hardware and software designs for this project are based in part on the ideas, code ...

Of course, the concept of "lock" may include a mass of devices that block the passage into the room (building, territory, etc.). All these devices in access control systems are referred to as actuators. In this paper, we presented a simple RFID reader for security access. This security ...
An Arduino or compatible executing the Sketch using this library. Prices vary from USD 7 for clones, to USD 75 for "starter kits" (which might be a good choice if this is your first exposure to Arduino; check if such kit already includes the Arduino, Reader, and some Tags). Proximity ...
