Discuss major limitations of eCommerce?

[Hira]

Despite all these benefits, EC has some limitations, both technological and non technological, that have restricted its growth and acceptance. One major technological limitation is the lack of universally accepted security standards. Also, in less-developed countries, telecommunications bandwidth often is insufficient, and accessing the Web is expensive. Non technological limitations include the perceptions that EC is insecure, has unresolved legal issues, and lacks a critical mass of sellers and buyers. As time passes, the limitations, especially the technological ones, will diminish or be overcome.
