Hello, maybe my question would be lost in the forum, but has somebody work with RFID tags? I know I can read them, but can I write or modify the inside data? Does anyone know where can I find more about this?

As I already replied:

MATLAB has no RFID related functions. If writing the tag is more complex
than opening a known device name and writing a stream of bytes, then you
will probably have trouble doing in with core Matlab. If you happen to
be using Windows, then you might perhaps be able to call an ActiveX
control. Or perhaps the Instrument Control Toolbox would be of help. And
of course if it is possible to control the writing through a C program,
then you could make the the C program callable from Matlab.

In short, writing RFID tags is not one of Matlab's strengths, but you
could likely do it from Matlab if you work at it long enough.


To which I will add:

It sounds to me as if you do not know how RFID tags are written or
modified. The mechanics for doing so are not a Matlab question. When you
have researched and found out what kind of device you need to use, get
back to us and we _might_ be able to tell you how to interface with the
device.
