How do I buy BBW and Amazon apps for someone else?

I just got a Z10 for my daughter, and obviously I don't want to give her my credit card number for purchasing apps. So how do I get her a paid app without entering and saving my payment info on her phone?

Also, I have some paid apps that I can't use on my Passport, but she will be able to use. Is it possible to transfer them to her?

TIA.

Set up the accounts on her device, with your billing info, but do not give her the password to complete the order.

Another method would be to apply a prepaid Visa/MasterCard to her billing profile, but only load it with her allowance amount.

As for transferring a paid app, you would need to contact the app author to see if they would facilitate it.
