I am working on a C# project which is related to Write/Read RFID NXP tag. Reader model is Feig obid i-scan MR102. This is USB device. They provided SDK. I can read default serial number of NXP tag with this SDK. My problem is, I need to Write ISBN of a book in NXP tag and Turn security ON when the book indoor into library. When the book will be issued, I need to Read the ISBN of this book and Turn security OFF. I am attaching the SDK, if you know how to do this, please give me solution. Thanks.
