I've recently started using the new ScotEID system for transporting weaners to their new owners and was pleasantly surprised at how easy it all works.
For me, one of the many benefits is being able to login and see the details of every movement, without having to look up my croft file. I haven't had a visit to the abbatoir yet but hopefully that will be just as easy.
I'm sure there must be a downside somewhere but I've not found it yet.
