F-1 Bitmap

Description

ISO 8583 uses a concept called "bit map", where each data element is assigned a position indicator in a control field, or bit map. The presence of a data element in a specific message is indicated by a one (1) in the assigned position; the absence of a data element is indicated by a zero (0) in the assigned position. Each application transaction includes one (1) bit map. A bit map consists of 64 bits numbered from the left starting with bit 1.
