Most card issuers allow you to apply for their credit cards online, especially when they offer instant decision cards. Online applications are easy, convenient, and in many ways similar to in-person applications. You will need to provide your personal information, including but not limited to your name, ID, verifiable address, social security number, and employment status. If your online application has been approved, to start using your new card you will first need to sign a contract which you will either receive via email or by post. While online applications are generally secure, you still need to be careful. Only apply through a secure network (such as your home Wi-Fi), and only use your own device.
