devices exist that can access and retrieve data from the internet . these devices use a web - browser of some form to achieve this end . to retrieve a - rid render web - pages using a web - protocol , such as , for example , http or wap , requires a relatively sophisticated client device . such a client device requires large amounts of memory and a relatively powerful processor to run the web - browser to access data sources such as , for example , the internet directly . however , often users are only interested in specific , small volume , data such as a current share or stock price , exchange rate or temperature , for example . hence , using such a relatively sophisticated device as described above to achieve a relative simple aim is unsuitable . therefore , embodiments provide a data communication system comprising data specification means for a user to specify at least one data item and preferably a number of items of data , data capture means for capturing specified at least an item of specified data from data sources and a data display device for downloading , wirelessly , at least one item of data from the data capture means , wherein the data display device is incorporated in a personal article .
