We know that how mobile phones changed the life style of people and within the few years of development in the pos industry, the point of sale hardware used with mobile devices has become more and more dominant in industries like restaurants and retail stores. When talking about restaurants and retail shops most of you think that the primary goal of pos here is payment processing. Yes it is, but the companies now become more smart and they focus on different parts of the consumer buying process, such as ordering, up-selling or so-called "suggestive" selling of complementary products. The most important considerations when integrating mobile hardware into a POS system (new or existing) are security encryption, wireless capability, and durability.
The reasons for integrating pos hardware into mobile phones are mainly to offer a cool factor to customers and also it is a lower initial investment. Most of the industries are now started to know the importance of pos hardware integration in mobile phones and they believe that it will give the comfort level to their customers with modern technology.
