Identify All
In this example the RFID reader identifies all the tags, independently of the tag type, in the reader's range. The program performs the following steps:
...
1. Gets the RFID parameters from the first driver and, using them, opens the connection to the RFID reader.
2. Checks if the driver supports the "identify all" attribute and displays how many tags are in range.
3. Displays the tag ID and tag type for each of the detected RFID tags.
