I have a small retail shop and I'm looking to order a counterfeit bank note detector. Does anyone know much about them or what to look for when you buy one? I found this site online and they seem to have quite a range of counterfeit note detectors zzaponline.com/counterfeit-detectors
I think I will order from them but I'm not sure which machine to go for. If anyone happens to have used a detector before in retail, I'd be grateful for your advice on which to purchase.
