What is the latest on this? I seem to remember that there were a few fledgling systems a while ago. Has this changed? Is there a way to readout SI cards on an iPad or iPhone (or other mobile device)
There are Java and C# libraries for SportIdent, so in principle one could (for iPhone/Pad, Android or Windows Phone or tablet, or Mac for that matter). Googling seemed to show a German language SportIdent iPhone app, but I didn't dig deeper into what it does. I've had a vague notion of creating a mobile app for my club, which, in addition to some basic functions like schedule and directions when out of cell range, or registering for events, would also have event results functionality using one of those libraries. (It would download the list of registrants from the club database automatically before each event, so that everyone who arrives with the app can potentially do resukts, without worrying "who has a thumb stick with the reg data and list of who's signed the annual waiver?".) But I've been distracted by other activities. If there's a clamour for such a thing, I might work harder on it.
There's an app for Android called SI-Droid Event. I downloaded it. It looks like it can handle a small event or a training session. There is a free lite version that you can download to make sure that your device can connect to an SI master station. The full version is $5 US.
I wasn't able to make a USB-serial attached SI master box work through either of two different OTG cables with a Dell Venue 8 tablet. Also tried inserting a powered USB hub in the equation in case lack of power was an issue. Can't recall whether I tried with my Android phone.
