Does it have another cross lightly engraved on the head, 45 degrees off from the main cross? Then it's Pozidriv. Does it have a small circular dot in one corner

Does it have another cross lightly engraved on the head, 45 degrees off from the main cross? Then it's Pozidriv. Does it have a small circular dot in one corner of the head? Then it's JIS.
There may be the occasional unmarked JIS screw though.
