Short answer
Pacemaker and ICD makers advise keeping magnets at least about 6 inches (15 cm) from the implanted device, and a badge magnet worn on the chest can sit closer than that. Anyone with an implanted cardiac device should use a pin or clip back, or wear the badge on the opposite side, and follow their doctor's advice.

What to know
- Choose a pin or clip back for anyone with a pacemaker or ICD.
- If a magnet is used, wear it on the side away from the device and ask a doctor.
- Ask staff privately; you do not need a reason to offer a non-magnet badge.
- Same badge front, different backing, so the team still matches.
