RFID (radio-frequency identification) is the wireless non-contact use of radio-frequency electromagnetic fields, for the purposes of identifying and tracking tags attached to objects. This is the ID-20LA, a very simple to use RFID reader module from ID Innovations. With a built in antenna, the only holdup is the 2mm pin spacing. Power the module, hold up a 125kHz card, and get a serial string output containing the unique ID of the card.

Note: The new ID-20LA is essentially the same as the older ID-20, but has a lower input voltage.

The RFID Reader ID-20LA 125kHz is a reliable RFID module designed for Arduino projects, smart access systems, embedded electronics, and wireless identification applications. This module allows users to read compatible RFID tags quickly and accurately using 125kHz RFID technology.

Because RFID systems are widely used in automation and security projects, the module helps developers create wireless identification systems without complicated hardware design. In addition, the compact structure makes installation simple in embedded electronics and prototype circuits.

Many students, makers, and engineers use this RFID module for automation systems, attendance systems, and smart electronics projects. You can also combine it with the <a href=”/product/arduino-uno-r3/”>Arduino UNO R3</a> for RFID communication and identification applications.
