I use a VPN, can't use wireless and abide by the same user agreement I have at work. The VPN allows only me to enter while my PC can still be used for non-banking tasks (whatever that would be) since it is mine. This also allows you to monitor whatever you need to while they are online.
If you give them a laptop, make it just for work. If they use a personal PC, make them follow your existing rules.
