The reception of a printed bill has been in global use as the proof of a transaction. Originating as a handwritten bill, the transaction billing has evolved with the advent of printers and computers, and are now an indispensable part of Point – of – Sales systems (POS). However, with the rapid expansion of business entities as well as the increase of wants of consumers, conventional billing consumes large volumes of paper, even in an organizational basis. Most of the bills generated as such are immediately disposed after an initial inspection. Hence, the paper used for billing has a very short usable lifespan and the paper along with the ink become waste. With the rapid advent of the smartphone providing an internet connected handheld portable computational device for the public, proposition of an internet-based virtual billing system has become timely. Although previous studies have been carried out on implementing virtual billing systems, the potential of smartphone has not been utilized in the practical implementation of such systems. The overarching goal of this study is to reduce reliance on paper for billing work. This outcome of the study aims to develop a virtual or a paperless billing system, with interfaces for the storefront user and consumer user. This virtual bill will directly appear on the smartphone application, which uses an Android operating system. In addition to the reduction of paper usage, this approach will also help the customers keep track on the expenditure for a certain commodity per vendor over a particular time period without manually having to calculate the expenses. The outcomes of this research will evaluate the feasibility of practically implementing such a paperless billing system in the context of Sri Lankan business entities.
Factors which generate Pronunciation Difficulties for the Undergraduates of University of Kelaniya

The research paper will focus on the fundamental pronunciation problems faced by the randomly selected undergraduates who learn English as a second language in the University of Kelaniya. The sample of this study consists of the undergraduates belonging to faculties of Humanities, Social Sciences and Management in the University. The collection of data was done as a semi structured interview (Pronunciation Test) and as a questionnaire. The sample consisted of forty undergraduates for the questionnaire and ten undergraduates for the semi structured interview. The research was carried out in September 2015.The study identified two major problematic areas; how the puberty age affects for pronunciation and how the rural and urban distinction affects for pronunciation. The findings show that undergraduates who started learning English before puberty are more fluent in English than others and undergraduates from urban areas are more fluent in English than those who are from rural areas. The study also revealed other pronunciation problems such as anxiety, family background, influence of the first language and incomplete knowledge about grammar and vocabulary. Based on these findings the researcher recommends that the undergraduates will be able to overcome these pronunciation difficulties and speak in English correctly by implementing teaching methods regarding pronunciation in English classroom, giving proper phonetic training, practicing pronunciation activities and having good motivation as well.
