Every man should have his identity card with him. That card should mention his blood group, complete address and telephone number for contact, in case, some serious accident takes place.

• Blood cannot be transfused until its group is mentioned in the card.
• The police needs this information especially when the accident is fatal.
• In case of emergency, he may forget his address and may need the card to contact his house.
• None is supposed to forget his phone number under any circumstances.
• When the seriously injured person is helpless to tell his blood group, this information would suffice to indicate the required blood group.
