Probably the name, but for the most part the other information is not useful in the field. As stated many a time, if you have allergies or a medical condition, wear an appropriate Medical Alert tag or Medical Alert jewelry item. With rare exceptions, wallets, cell phones and other forms of information are frequently gathered by law enforcement. EMS will look for Medical Alert info and possible ICE, but rarely is it useful to spend the time looking/searching for other forms of information. Law enforcement and hospitals will generally look at the more discrete or “hidden” forms of information. Various EMS jurisdictions may have different SOPs/SOGs on looking for such information, so hearing from a few others EMS providers may be useful.
