How about shabbos pens? These are felt-tip pens filled with temporary ink, intended for use by medical professionals on shabbos. Because the ink is temporary, using them on shabbos violates a d’rabbanan and not a d’oraisa. (Depending on the writing surface & exposure to light, records must be copied after shabbos is over).
