ISX Charts, page-544

When one uses ISX grade pay identity for consumers and businesses, then logically most transaction will be genuine. For the ones that slip (say 1% error), wouldn't insurance take over? I'm not through with these scheme's much, so any views would be great. To put it simply, instead of paying now, the consumers can pay it in splits or a later date. The genuine transaction has already taken place. Well if someone goes bankrupt right before payment, that will be no different to the 30 days credit - card issuers already provide?
