How to transfer the iPhone contact to computer files

I’d like to share useful software with all iPhone users. It is the Tansee iPhone Transfer Contact. With it you can backup the contact and contact's photo to computer. You can transfer the iPhone contact to computer as a txt file or a ANTC file. Before the transfer, you can choose to transfer all contacts or a single contact. In ANTC file condition, you can protect the file with a password to keep your privacy. I have kept it in my computer and I really benefit from it. With it I am not puzzled about the full iphone contact anymore.
