The main purpose of this RFID reader is to identify and track tags attached to object, it does that through the use of radio-frequency electromagnetic fields. It’s ID-12LA (same as ID-12 but with lower voltage input), simple, easy, and fun to use! It comes from ID innovations.
Note that the antenna is built into it and so the only holdup is basically 2mm pin spacing.
These are the steps you should follow in order to use it correctly:
• Power the module
• Hold up a 125kHz card
• Get a serial string output containing the unique ID of the card.
