It has been a constant goal at Unibanco: develop systems to reduce clients dependence on trips to the branches. In 1991 it came up with the 30 Hours concept - Unibanco available 6 hours at the branches and another 24 hours through other channels. The 30 Hour banking revolutionized service by blending convenience and cost economies, earning strong brand recognition and popularity.

The first service developed was the Call Center, which at the beginning completed roughly one-half of requested phone transactions through live customer service. Since 1998, when tone phone sets became standard, the vast majority of transactions is completed through phone keypads. According to the latest survey conducted by Ibope (Brazilian Institute of Public Opinion and Statistics), in November, Unibanco received an overall 6.51 grade for its services on a 1-7 scale.

Unibanco also pioneered, in 1999, the offer of internet banking for its clients. The internet-banking user-base has grown exponentially, reaching 1.7 million in 2004, when the number of transactions/year hit 170 million.
