> Why can't companies like Visa, Mater Card, etc give ID Password facility for easy pay online?

They already do. You can pay with a username and password, just like PayPal, or Amazon Pay, etc.

It's up to merchants to accept and integrate them in their shopping carts.

You can if you use a virtual credit card such as the one I was CTO of (Entropay / Ixaris).

But ID and password are not necessarily 'better' by many important metrics including ease of use and security, eg is entering such info into a PoS terminal, or your phone near one, easy and safe? At your desk is less of a challenge.

Most Debit Cards in India require a PIN to verify the transaction on POS (and sometimes online as well, in case One Time Password doesn't work / not available) which actually makes sense.

Now, the same debit card (if international) would not require a pin/otp in case of transaction happening on a US payment gateway. Now, it really depends how banks (or the country) handles the credit/debit card transactions.

Here's a good read on why US has the least secure cards: https://www.theatlantic.com/business/archive/2016/03/us-dete...

There are tools to easily automate this process.

In fact, I would say it is too easy to automate this process, and there should be a standard way of requiring the user to perform some sort of interaction that can’t be automated away. Of course, the user should be able to choose when this functionality is required, like for all purchases over a certain amount or something.
