Bitcoin ATM

[TheOnly1]

I got a Bitcoin ATM.
I was in contact with Swiss Financal Market Authority, to ask for requirements to operate this ATM.

Its all not a big deal, exept one thing:
I have to technically prevent that peoples send Bitcoins to anyone else exept to them self.

Someone got an idea??

There is only one thought I got:
I print a lot paper wallets and allwo peoples only to load the bitcoins to those paper wallets.
Like this I can be sure they own the Bitcoin and nobody else. As soon they leave the ATM of course they are free to send them to any place they want.

But like this the question is, how to make sure peoples use only the paper wallet I give them?
Does someone know a wallet or a software (via API) which is able to allow transactions only for specified adresses?
Like this I could enter the adresses of the paper wallets in the ATM wallet, and all other adresses would be blocked for ATM withdraws.

Thanks

I've anticipated this when I started this thread: https://bitcointalk.org/index.php?topic=457930.msg5049997#msg5049997

This is question. This is all about financial regulation. Where are you going to place your first ATM?

What brand ATM did you go with?

Its a Lamassu ATM, it is installed in  a Cafe in Zurich.
How are these questions related with my problem??
