Carrying an emergency contact card is always useful. Imagine if something were to happen when you were out and about and you didn't have your phone with you? Would you know anyone's number? Probably not, after all, these days, we put it on a sim card and forget all about it. It's not like back in the day when we knew everyone's number off by heart!
These Emergency Contact Cards are made in nice bright colours so they are easy to spot. They are single sided, bio-degradable and measure 86mm by 54mm which is the same as a credit card (3.38 inches by 2.13 inches) so fit nicely into purses and wallets.
