RFID Walk-In Reader
The RFID Walk-In Reader is a more advanced version of the RFID Show and Go model.
How It Works
With this model, students need not flash or show the card to the reader. Instead the reader itself automatically detects the card, which the student has to carry with him. The reader then marks the student’s attendance and sends an instant SMS to the parent’s mobile informing them about his or her entry or exit into the school/college premises.
