> And besides, big banks still have to deal with checksum-passing iban typos on a daily basis. IBANs only have two check digits.
Actually the checksum was designed especially to deal with typos. As such, dealing with typo errors is usually not an issue at all.
What they do have to deal with is maliciously created IBANs though. However, if the account an IBAN should point at doesn't exist then the transaction usually just bounces.
