Standard and Pro Type 5 tags from Texas Instruments do not support the Get System Information command which means they cannot be read with the current neard code. Fortunately, both types of tags have eight, 4-byte blocks so that information can be filled in instead of issuing the Get System Information command to get it. With this change, Standard and Pro tags can now be formatted, read, and written.
