This paper contains overview of key technologies for mobile banking client implementation and presents J2ME mobile banking client development. Banking applications follow a trend of mobile application expansion. Banking services on mobile device presents for current services new channels of distribution, implemented in order to satisfy ascending customer needs. This enables service access 24/7 from every place. This was enabled by new mobile devices, which possess excellent characteristics like large processor power, large amount of memory, enabled Java programming. On the other part, mobile providers implemented 2.5G networks, which use GPRS as information bearer. This type of networks enable greater amount of data to be transmitted between client and server, using much securer protocol and stable connection. User services were firstly realized using WAP applications, which had some disadvantages in terms of security. These applications were useful for less powerful mobile phones. Next generations of applications are client server mobile applications. These client applications need powerful mobile phones, because they are Java applications. These applications implement secure API and web service technology
