Mr. Michael Sheahan:

It is not simple. It is not as simple as sticking a microchip in a horse and you get through the system. It does not work like that. The microchip has to be registered on our central database, the microchip has to be a correct microchip and it then has to match the passport. Simply sticking a microchip in a horse will not allow you to beat the system. We are not sure yet how this individual horse apparently beat the system. We have some theories but we are not sure.
