According to the original design, IC health cards have an electronic patient chart function that allows doctors to look up basic personal information, including medication allergies, heart disease, high blood pressure, and similar issues. This function would also prevent problems with obtaining and reading charts when patients switch clinics and would reduce difficulties in inspecting medical records and waste from duplicating medical tests at different clinics.
依照原先設計，健保 IC 卡具有電子病歷的功能，載有個人基本資料，例如過敏性藥物、心臟病、高血壓等資訊，便於醫師查詢，亦可避免民眾更換醫院時，碰到病歷調閱困難，各種檢驗重複浪費的缺點，立意良善。
