It depends. If you use an initial config file i.e. for scan, it should be
possible to do this separately for each transponder.
Adding this in the driver is not a good solution: This is country depending
and the offset is not constant.
A better solution would be either to handle this in the scanning program
or in an extended offset search in the driver.
