Reads balance data from a given card account addressed by
"account-id".
Remark: This account-id can be a tokenised identification due
to data protection reason since the path information might be
logged on intermediary servers within the ASPSP sphere.
This account-id then can be retrieved by the
"Get card account list" call.
