Create your own "Read/write memory area" application
Follow the steps below to create your own application for reading or writing user data:
1. Establish the connection to the reader ("brp_open_usb_session" or
"brp_open_serial_session").
2. Check cyclically whether a transponder is located in the read range of the reader
("vhl_select").
When a transponder is located in the read range:
– The transponder is recognized.
– You can read data from the memory area with the "vhl_read" function.
– You can write data to the memory area with the "vhl_write" function.
3. Terminate the connection to the reader ("brp_close_session").
The source code of the demo application can serve as an example for your own application.
