mobile technology and its benefits?

Examples of mobile IT devices include:

laptop computers
palmtop computers or personal digital assistants
mobile phones and 'smart phones' - high-end phones with more advanced capabilities
global positioning system (GPS) devices
wireless debit/credit card payment terminals
Mobile devices can be enabled to use a variety of communications technologies such as:

wireless fidelity (WiFi) - a type of wireless local area network technology
Bluetooth - connects mobile devices wirelessly
'third generation' (3G), global system for mobile communications (GSM) and general packet radio service (GPRS) data services - data networking services for mobile phones
dial-up services - data networking services using modems and telephone lines
virtual private networks - secure access to a private network
It is therefore possible to network the mobile device to a home office or the internet while travelling.

Benefits
Mobile computing can improve the service you offer your customers. For example, you could use your laptop computer to give a presentation. You could then transfer PDFs of your product literature to your client's computer. Or you could connect remotely to your diary to arrange a follow-up appointment. Alternatively, you can enable customers to pay for services or goods without having to go to the till. For example, by using a wireless payment terminal diners can pay for their meal without leaving their table.

More powerful solutions can link you directly into the office network while working off site, for instance to access your company's database or accounting systems. For example, you could:

set up a new customer's account
check prices and stock availability
place an order online
This leads to great flexibility in working - for example, enabling home working, or working while travelling. Increasingly, networking 'hot spots' are being provided in public areas that allow connection back to the office network or the internet.

Drawbacks
There are costs involved in setting up the equipment and training required to make use of mobile devices. Mobile IT devices can expose valuable data to unauthorised people if the proper precautions are not taken to ensure that the devices, and the data they can access, are kept safe.
