Disadvantages of E-paper

Even though E-paper provides many advantages to people and the industries, it is still not perfect. E-paper is meant to replace traditional papers and other technologies, however, traditional paper can never be completely replaced by E-paper. Many people still prefer manually writing on a piece of paper as a way to better understand what they wrote. Also, most students and business people still print official documents or projects from their computers. Specifically for signing official contracts with customers. The following disadvantages are:

• Low Refresh Rate. At the moment, E-paper prevents the producers from installing sophisticated interactive applications such as high speed moving images, adding the mouse hardware, etc. Using simply a reflective can save large amount of power but it also slows down the processing speed of changing an image or text.
  

• The feeling: People still prefer paper. The number of people who subscribe for books and newspaper are in fact decreasing since many news and entertainment can be found on the net. Many offices and business still use paper for signing contracts, hard copy of documents, etc. Even majority of students still write on textbooks and notes instead of bringing their own laptops. There were people who mentioned that they did not want to lose the feeling of holding a book and the effort of writing.
  

• New crime. As technology is growing, so is crime. For example, there are new criminals such as hackers since the invention of computers and internet. If information is not deleted once viewed, then information can be easily stolen if not take care of properly. Especially since information can be transmitted wirelessly. Criminals can always find their way around new technologies. Many industries might need to enhance their securities in case if crime occurs and it can be anytime and anywhere!
  

• Ready or not? E-paper has began in 1989 by Nick Sheridon. The acceptance of E-paper might take longer than expected. Some people, but not most, are still not comfortable using new technologies. Further development is still needed for E-paper. Therefore, it might take a while before industries and offices can adapt to this major change.
