arielptson Anatomy of a Co-Branded Credit Card

Great to know, thank you for the information and source.

arielptson Anatomy of a Co-Branded Credit Card

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.

MasterCard: https://www.mastercard.us/content/dam/mccom/en-us/documents/...

What can vary from issuer to issuer is the processor/network costs.

Official gov statement, only states that:

"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.

arielptson Final – A credit card built for the 21st century

Hello.

Will Final actually partner with a financial institution to issue a card that I'll have to apply and have its own limits.

I'll be able to use my own credit card, and Final is just a proxy?

Thank you!
