<p>
The PIN encoding format for pin data generation as specified in ISO 9564. Amazon Web Services Payment
Cryptography supports <code>ISO_Format_0</code> and <code>ISO_Format_3</code>.
</p>
<p>
The <code>ISO_Format_0</code> PIN block format is equivalent to the ANSI X9.8, VISA-1, and ECI-1 PIN block
formats. It is similar to a VISA-4 PIN block format. It supports a PIN from 4 to 12 digits in length.

<p>
The <code>ISO_Format_3</code> PIN block format is the same as <code>ISO_Format_0</code> except that the fill
digits are random values from 10 to 15.
