We often go in situations where we have to make a transfer. This happens, for example, when shopping online. Not everyone trusts by the fast transfer offered by Payu or Dotpay.

Unfortunately, we usually don’t know at which bank the account is located to which we made the transfer. And this information is crucial if we want to specify the length of transaction posting.

Spaces between numbers were also introduced and divided into groups. “Spaces” were used for better readability and a comfortable option of rewriting the number, eg on a form or form. Today, we can thank its originators for this activity, because we can easily determine which bank has numbers behind the account number.
