I'm not sure how this could be true. Do different JSON parsers interpret integers differently? There is no precision problem that I foresee or am I missing the obvious?

Developers using ISO8583 have managed for some decades as I say. There is a finite set of global currencies and knowing how to convert them from minor currency to a decimal if required is pretty easy to accomplish. Any new currencies like Bitcoin have to define what their minimum unit of account is and anyone using that currency can fairly be expected to need to know that.

This approach's appeal is in it's simplicity and yet interoperability and flexibility.
