The delivery of services was always linked with actual technology in some way to facilitate and make this process more efficient. With emerging the information and communication technologies (ICT, especially Internet and web technologies in the last decade) new type of services started to appear. These services are called electronic services (e-services) and their concept is a subject of research for many years. There are also several definitions of e-services slightly differing and often depending on research discipline. However, we can mention two of them [7]:
E-services distinguish three main components: service provider (public agencies, universities, commercial companies, etc.), service receiver (citizens, students, firms, etc.) and delivery channel (i.e. technology used – Internet, television, telephone, radio, CD-ROMs).
E-services can help in accessing broader customer base. They can be available 24 hours a day and accessible from anywhere. Installation and operation costs can be significantly decreased.
Since the electronic services are currently provided in a digital form they can be also considered as digital services in general. There are a lot of applications of e-services such as e-business, e-government, e-shopping, e-health, e-learning (e-education), e-banking, e-consulting, e-working. However, we can also meet other words emerging which are associated with this domain such as e-society, e-entertainment, e-culture, e-science, e-inclusion, etc. Recently, there has been rapid progress in mobile communications and computing. Mobile phones, tablets, PDAs and various other wireless enabled devices are common part of end user’s everyday life providing sufficient usability (comfort of usage) and high instantaneity (speed and efficiency of transaction/activity execution). Then electronic services that are provided and consumed through wireless/mobile handheld devices are often called mobile services (m-services) [8]. We can encounter e.g. m-government, m-health, m-learning, m-banking and other m-services.
