RF tags overcome European hurdles

Explains how radio frequency tagging has established itself in Australia and the USA, where 915MHz is acceptable for this purpose and pulsed power allows read distances of 7m or more to be achieved with a passive (no batteries) tag. Points out that in Europe there is no one acceptable frequency available in every country, so a pioneer Australian company has adopted 458MHz for UK use and 433MHz for Germany and some other countries. Describes some of the successful applications so far and points to future possibilities including monitoring of BSE in cattle.
