Precisely. From my experience (in developing countries where the interest is very high) the banks makes much more money from the defaulting. The exchange merely pays the costs.
Actually the interchange does not vary per issuer.
It can vary per card type (pre-paid, debit or credit), card level (basic or signature/elite, etc.), type of transaction (CNP or present), Merchant type (supermarket, airlines, etc.) and some other rules, depending on the scheme and the region (US, Europe, etc.).
For instance the Interchange (to be paid to the Issuer) when a US issued MasterCard Debit Card is used in Gas Station is 0.70% US$ + 0.17 with a cap of US$ 0.95, but when used in a Restaurant is 1.19% + US$ 0.10 without caps.
Debit cards from big banks are covered by the Durbin Amendment which fixes the interchange to 0.05%. Smaller banks are regulated by Visa/Mastercard rules on interchange.
It's still "under development", while I add a few missing features, but as you can see from the README these are only for fairly obscure parts of the regex language! - E.g. POSIX groups, named properties, character set intersection, ...
"IP address urgent needs caused by natural question of how to introduce IPv6, although other new industry solutions IPv9 IP addresses, etc. are also emerging, but IPv6 is still by far the most practical, the most sophisticated methods" [1]
Very distinct than the "chinatechnews.com" statement [2]. Just plain poor journalism.
