HomeBanking is past - OutdoorBanking is now!

With OutBank 2005 you can visit your bank whenever and wherever you want – entirely without your computer.

After you have installed the application on your SmartPhone, OutBank 2005 allows you to manage your accounts from different banks very easy and secure via your mobile phone. Based on the accredited German safety standard HBCI and FinTs respectively your encoded account data will be transmitted between your bank or your thrift institution and your SmartPhone. In contrast to the WAP-Banking there will be only encrypted ‘net’ information transmitted. And there is no thirt-party component (e.g. a Proxy) between.

That means that the transmitting volume and the duration will be reduced to a minimum.

Thus, MobileBanking with OutBank 2005 is to a considerable degree less expensive and in addition significantly more convenient than WAP- or SMS-Banking.

Fill in your bank transfer without any hurry. The data will only be sent to the bank when all of the information is existent. For GPRS or UMTS the amount of data thereby incurred will be minimal – for example, an inquiry of your account balance requires only about 5-7 Kbyte.
