• Internet Service
  
  
• Firefox browser version 2.0 or Internet Explorer version 6x or version 7.0.
  
  
• Adobe Acrobat software (Reader and Writer), to convert documents from word processing software to Portable Document Format (PDF), or to save scanned documents to PDF
  
  NOTE: This is something you will have to purchase - downloading from the Internet only gives you Acrobat Reader and will not allow you to convert documents.
  
  

It is likely that most Internet users will already have the necessary hardware, software and Internet service, with the possible exception of Adobe Acrobat Writer.
