Beginning in the middle of the 1950s, the Comptoir National d’Escompte de Paris (CNEP) established tabulating centres. These service shops processed the bank’s information with mechanical or electrical-mechanical equipment that could calculate, process and publish the data.
In order to optimise the management of its operations, it equipped itself with new machines: interpreters, tabulators, autonomous calculators capable of multiplying two codes figures on a perforated card, etc. This was a veritable technical revolution that the Comptoir National d’Escompte de Paris (CNEP) underlined in its image campaign titled “You are in the 20th century.” This poster praises the sophistication of its calculation and data management equipment. In March 1961, CNEP passed an additional milestone when it deployed Gamma 60 computers in its administrative centres. Its production was increased tenfold very quickly. This technological revolution made it possible for the CNEP to renew its image with the general public.
