If the punching record is created properly the ecard will download with that information. If not then it is 'mp'. Keep it simple.
Unfortunately this is not the case.
A competitor punches and the SIAC card flashes to confirm this has been done.
The box doesn't provide any feedback (as it would do with contact punching) so what more should the competitor do ? As far as they are able to tell the punching record has been created properly.
Only at download does it become apparent that the punch hasn't recorded on the card.
SIAC punches are not recorded in the unit, so there isn't even the possibility of checking for an intermittently malfunctioning box.
A system designed to produce the outcome that we saw yesterday.
