RF Module Card

The RF Module Card is a compact and versatile wireless communication device designed for short-range radio frequency identification and data transmission applications. Often used with RF readers and modules, these cards enable secure and contactless identification, access control, inventory tracking, and wireless data exchange. Operating typically at frequencies like 125 kHz or 13.56 MHz, RF module cards come in various formats such as RFID cards, proximity cards, or smart cards. Compatible with common RF readers, they are widely used in security systems, attendance management, asset tracking, and IoT projects.
