Neosurf Prepaid AU is a simple, secure, easy, and convenient way of paying safely on the internet, without the need to enter a sensitive bank account or credit card. You don’t need to register or provide personal information and your Neosurf prepaid is ready to use immediately.
Neosurf prepaid cards or Neosurf vouchers are a good alternative to credit cards for online payments. Since you can only spend the amount of prepaid credit you purchased, you will never be able to spend more than what you already paid for. 
As such, overspending is not an issue! There are over 20,000 websites where Neosurf is accepted.
