Not sure if anyone posted anything like this before but..

I noticed problems of scamming in trades. I wonder if a third party(trusted) is to handle trades, would things really work out and would scamming risks be substantially minimized?

eg. Trader A wants to buy handphone from Trader B. Trader A sends RM$450 to third party first. Trader B confirms that third party has money in hand, and sends handphone to Trader A. Trader A tests out the handphone. If conditions agreed upon are met, third party sends money to Trader B. Else, Trader A gets back his money when Trader B receives back his phone.

Though it still depends on the trusted third party, but maybe those members who had alot of successful trades or "clean record" are interested in taking the job? With commission of course, though i don't know how much should it be. This method would be more costly though and not suitable for small trades.

Trusted third party could also be listed and stickied.

Sorry if this was posted or discussed before, or was posted in the wrong section as i'm noob. Waiting for your thoughts on this, thanks.

money from one or both party as fees?
