EE APP is a web based application which facilitates capital one costumers to apply for credit card respond them with the result approve or denial and if approved allows its user to create online profile of his/her card. The user can get an experience of linking his/her card to an existing account if he already has online profile in Capital One. Further if the users account is verified he can be directed to account summary page with the capability of jumping from one account summary to another and if the account is not verified then user is redirected to intermediate page.
