Parallax RFID Read/Write: Basic Demonstration
|
||||
|
||||

||||
Contact: support@parallax.com
|
||||
|
||||
Program Description:
|
||||
|
||||
This program demonstrates the basic functionality of the Parallax RFID Read/Write
|
||||
Module (#28440). Data is displayed using the Arduino Serial Monitor.
|
||||
|
||||
The module is compatible with EM Microelectronic EM4x50 1kbit R/W 125kHz tags.
|
||||
These tags can be used in a number of ways:
|
||||
1) Read-only by reading the tag's unique, non-changing serial number
|
||||
2) Read/write up to 116 bytes of user data (publicly accessible)
|
||||
3) Read/write up to 116 bytes of user data (password protected)
|
||||
|
||||
Please refer to the product manual for full details of module functionality
|
||||
and capabilities.
