- The Seed Studio 125KHz RFID reader module is designed for reading the codes from 125KHz RFID chips/cards and is compatible with read-only tags and read/write tags.
- It could be used in office/home security, personal identification, access control, anti-forgery, interactive toy and production control systems etc.
- The RFID module will notify whenever a 125khz tag approaches, the tag serial number will be sent via the TX pin.
- This is an easy and cost effective way to RFID enabled your MCU (micro controller) project. You can also connect directly to a PC via the UartSB.
