To use this online Bitmap decoder tool, type or paste the hex value of the bitmap in the field below, and then hit the Convert button.
To use this function, type or paste the binary value of the bitmap in the field below and click the Encode button
Check the boxes corresponding to each field below and click the "Build Bitmap" button above to enable fields in the bitmap
Fastest way to learn is by enabling the ISO8583 fields below and watching the bitmap change in the binary representation, as well as the hexadecimal form
The binary representation is the actual map of bits. Each ISO8583 field is represented as a 0 or 1 in this array of bits
This binary representation is, of course , translated to its binary value by grouping every 8 bits into a byte
The binary form cannot be represented in ASCII, so we represent it in hexadecimal, on the left side
The bitmap is loaded in ISO8583 messages in binary or ASCII representation.
For ASCII, the hex value on the left is exactly what you will see in the message
For binary, you will see this hex representation if you have a hex dump of the ISO8583 Message
You can extract the bitmap from an ISO8583 message with the ISO8583 Message Parser
