Problem Statement: Value added propositions to card based electronic currencies

Opportunity a) : While most card statements ....could or would include the microscopic
              view of the transactions on the card

              ....given that each product or service procured ...have nuances of 
              guaranty , waranty or purchase deed ....requirement for some real life 
              scenarios.

              Deriving from how the Digital certificates ...are enshrined or being
              marketed as on date ....while taking into account the short commings
              ...and the reliability of usage of software (translating into guarantee
              or warranty!!)

              ....ability to maintain electronic transactions of the above 
              guarantee , waranty or purchase deed ....would be a viable proposition
              that offers a innovative market opportunity as a addon paid service.


Opportunity b) :
                  Ability to hold: Multiple currencies in account balances 

Opportunity c):  while or when using card based currency  offer a legitimate and valid contracts ...

                          internet or www based transactions offer  convinence but

                          are prone to vulnerabilities as in 

                          illustrated in "opportunity_exploit_DNSwithNAT.txt"  well
 
                          the data once captured can be re-used ...and what can be termed

                          as phising of data ...and some online portals engage in what may

                          be termed as auto-billing ...this individual is a victim of paypal,inc.


                  well ideal means is to set attributes on the server side database or
                  the card-company viz. when accessing using atm (more safer given the
                  context that they say they use properitory leased lines) or web-based login
                  or ivr based systems where-in  the card can be enabled or disabled for online web based transactions
                  say lockable with kind of code /  pin with true or false attributes.  


                  some credit card companies have implemented what is termed as validation 
                  and generation temporary credit card number termed visa/master card validation
                  and payment ...both the concept or idea as also the potential algorithms for
                  the same have been exemplified by this author.                                

             
 Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in 
      
       http://uk.geocities.com/ravivenkatus/projects.pdf
       http://ravishankarkv.tripod.com/projects.pdf
        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
