Bob Brotchie, a paramedic in the UK, had the original idea – over 75% of the UK population doesn’t carry any form of ID with them, and even if they do, it is not clear who should be contacted in the case of an emergency. He suggested putting an entry in the address of book of your mobile phone under “ICE” (in case of emergency), indicating the phone number to be called if you are involved in an accident or become incapacitated for other reasons. If you have more than one contact, you can label them ICE1, ICE2 etc. There is usually enough space in the mobile phone’s address book to add more information in the name / address fields – for example “mother”, “brother – work number”, or whatever.
The idea has spread rapidly in the English speaking world – for example, if you check out Vodafone’s web sites, you’ll find information on their New Zealand site, the UK site and vodafone.com. You don’t find a single word about it on their German site, however. Which is a pity, as the idea is a good one, and it makes sense to use the English acronym, rather than a local one (such as “IN” – im Notfall in German speaking countries for example) – many people go abroad on business or vacation and a standard acronym is the only way they are going to get their message across abroad.
If you follow this idea, you might also want to identify your mobile phone with a small label on the back, so that the medic knows who you are too. And remember, the ICE doesn’t make other forms of ID obsolete. It is still a good idea to carry some other form of ID, or medical details with you. Your phone may be damaged or the battery may not be charged when the paramedics need it.
