Automatic Identification System For AttendenceOn this instructable I will try to show ho w to interface a RFID sensor with the Arduino. I am using the RFID sensor from seeed studio the serial version of it. There are a few parts you will gonna need. I also bou ght some RFID keys. UPDATE: Now it works with IDE 021 Step 1What you gonna need?

This RFID Reader Module (Serial version only) comes with two54x85mm Rectangle Tags.
Designed in cooperation with Grand Idea Studio, the Parallax Radio Frequency Identification (RFID) Reader Moduleis the first low-cost solution to read passive RFID transponder tags. The RFID Reader Module can be used in a widevariety of hobbyist and commercial applications, including access control, automatic identification, robotics,navigation, inventory tracking, payment systems, and car immobilization.
There are a variety of transponder tags that come in different packages. Each tag has a specific range that is within10% of the given distance for each type of tag. The reason for the 10% is due to environmental conditions and RFIDmodules.
