Monetary Values
Values are represented as 32 bit unsigned integers (4 bytes) and in the lowest value
of currency. For example:
€50.00 would be 0x00001388
When sending or receiving a value the least significant byte is sent first. So in this
example [0x88] [0x13] [0x00] [0x00] will be sent.
Each type of note is identified by its value and represented using the standard format
outlined above. As an example, the values for Euro notes are:
Note (€)
5.00
10.00
20.00
50.00
100.00
200.00
500.00
