Are there more? I'm looking for some payment options that are irreversible (Don't have chargeback system)

Western Union is one.

That would encourage scammers as the people who get scammed have no way of getting their money back..
And google Checkout has a $10 chargeback fee.

We'll obviously it wouldn't be used for everyone but someone who owns a business like me and techno's gold shop, if we had a payment option like that it would be more preferred.

And yeah, I forgot to add Western Union.

You could always use a payment processor such as Plimus.
