Suggestion:
Place the name in the first line. If there is space, perhaps also the year of birth (day and month are not recommended).

Why:
Knowing the year of birth enables rescuers to determine the most appropriate treatment in an emergency.

Example:
Marie / 2013,
Mario Schmitz / 1979

Suggestion:
Use lines 2 and 3 (maybe line 4) for the most important contacts to be called in an emergency.

Example:
Mama +49 170 00* 123 *
Thomas +49 170 00****

Suggestion:
Share essential medical information with first responders in an emergency.

Important for allergies or other medical conditions.

It makes sense English
Terms (abbreviations) should be used so that foreign doctors can also use the information in an emergency
can work.

Alzheimer's - ALZHEIMER'S DISEASE
atrial fibrillation – A-FIB (ATRIAL FIBRILLATION)
Autism – ASD (AUTISM)
Diabetes type 1 – DIABETIC T1
Diabetes type 2 – DIABETIC T2
Hard of hearing – HOH (HARD OF HEARING)
high blood pressure – HBP (HIGH BLOOD PRESSURE)
Low blood pressure – LBP (LOW BLOOD PRESSURE)
Blood groups:
A negative – A NEG
A positive – A POS
AB negative – AB NEG
AB positive – AB POS
B negative – B NEG
B positive – B POS
O negative - O NEG
O positive – O POS

If there is still space, make a personal statement!
