Is it possible to make chip card or RFID card which will be a secured alternative for currency?

possible: yes, a lot of our money is fully electronic now anyways
smart: not so much, to fix any issue with security would result in a massive loss of freedom, getting a little too far into the realms of Huxley and Orwell

Yes, it is, and that basic technology now exists. The problem with it is, as is now an issue, it is no where near as secure as you would like to think that it might be. Hackers could still get your information, and drain off your money, just as they can now.Cash, just hard currency, with local transactions, is still one of the best ways to do things. .

No, absolutely not. there will be attempts, but for every try at security, there are a thousand folks out there trying to find a way around it. Your identity is not secure -- start there. there is a continuous battle to prevent "malware" from infecting your computer. yes, there will be attempts, but they are all destined to fail in the end.
