Agility comes from people, not from a technology. Treat your people with respect and you can change the systems as fast as you like - even if it is legacy infrastructure.
While "cloud" is a hot topic, the "cloud" experts will be treated as the new "stars". They are respected and well organised. Meanwhile, the "legacy" people are outsourced to the lowest bidder and managed on "cost" instead of value.

People first!

I proposed bill payments by SMS 20 years ago.

I was told that SMS was not secure.

The account holder will always need to be authenticated. And we will always want to be able to share our card with the kids (even though the PIN is supposed to be "personal").

Furthermore, the merchant needs to "look" trustworthy - the cards terminal helps in this process.

Unless replacing these elements provides significant benefit over the existing rails, cards are not going anywhere soon.

My experience with block-chain payments is up to multi-day clearance. With eCommerce card payments the only "delay" is my typing information in - the authorization via all these "intermediaries and third parties" is sub-second. 

Either I am missing something or this is marketing fiction.

I DO see huge potential in block-chain, but we need to be cautious that we are solving the right problem.

A loss to a civilization that works openly with each other. Fortunately, there is more in the world than self-centered Apple.

It will take some years - but like others, Apple will realize that working with others is essential to existence.

It is quite cool what is being built into cards now. This is indeed a good example - if they can get the reliability right. The products it supports are probably already on the market so it is a good convenience in certain markets.

Banks = Trust

Trust = got my back

I very much like banks. I trust them (like I trust my card not to run out of battery or fail due to corroded connections).

But if easy loan products that I haven't taken the time to understand put me in debt, I might take a different view.

The story with the battery gets worse - a replaceable battery? That means contacts that can corrode. There are enough unreliable electronics in the world without it affecting my cards.

As for the idea of so easily applying for a loan to buy something I don't really need - it will put me further in debt and only the loan sharks win. There must be some pain in applying for a loan to give me a chance to think it through.

A mobile phone is a general purpose computing device - it is inherently unsafe.

An EMV card is a trusted certificate that cannot be compromised (at least, less likely than the phone).

Also, my phone battery goes flat - my card does not.

One of the things I really like about my cards is that they do not require a battery!
