First off, your details are safe and secure. Your information is encrypted with the highest industry-specific standards which can be found in most banks.
Our payment service provider is TradeSafe Escrow. When the buyer deposits the funds, they will make payment to TradeSafe who will hold the funds in the middle (in a trust account). Once the seller has delivered what was ordered, then TradeSafe releases the funds to the selling party.
TradeSafe is required by the South African Reserve Bank to know the identities of the parties and that is why these details are required.
