What is the risk of fraud or of bad product and or bad vendors when both ends know each other? Why introduce a 3rd party in those transactions that gives back a fraction of its fee to the payer? (5) Instead why not reward repeat business with preferential pricing? (not directly possible but attempted via loyalty programs that cost a lot to deploy)
The credit is provided by the issuing bank (4). It can exist independently of the credit card network.
And with any electronic means, 1 is pretty much a given.
Credit 3rd parties still have a reason d'être if a solution that shortcuts VISA and MC when both ends know each other catches on. A Credit 3rd party is needed as an insurance policy when two unknown parties do a transaction; that insurance is bound to cost more than today given less volume; but it could be efficient if pricing would be market driven instead of diluted in 100-1 day to day transactions.
Thanks to the down voters, BTW. Again HN is showing openness to look at things from a totally non conventional angle. I think I'll log off for good. So long, and thanks for all the fish!
1) near immediate payment resolution
2) fraud protection
3) insurance against bad products and vendors - you can almost always get your money back if something goes wrong
4) credit accounts
5) points/miles/cash-back, at the expense of the vendor
