As for the receipt of emergency medical info, you can either enter an individual ID # online, call/fax it in, or text it. I texted my "lifepin" to the specified number and I got TWENTY NINE texts back with information about myself. That would totally suck if someone did not have an unlimited texting plan. Some of the texts were very short. Others weren't. Overall, it was pretty helpful and it would be easy enough for a first responder to get good info about a victim from the Finish Tags.
I'm not giving up on my Road ID. I like the wrist band way better for the Road ID. I haven't taken the Finish Tags swimming yet, but I imagine that it won't stay on the wrist as well.
