Tombstone engravings inevitably fade, but Arizona company Objecs says its virtual engravings last for several millennia.

Objecs’ RosettaStones are granite tablets that can be installed into tombstones, and can communicate with cell phones using radio-frequency identification. Each tablet contains up to six symbols, which communicate some basic information about the deceased, such as their home country, occupation and religion. When someone touches an RFID-enabled cellphone to the tablet, the phone instantly calls up an image of the deceased, along with a text description.

RFID, which uses one physical object to automatically call up information when placed near another object, won’t become common on U.S. cell phones until 2012. Phones without RFID can still call up the information through a Web site listed on the tablet.
