Methods and Systems for Identification of an Eye-Mountable Device

摘要

An eye-mountable device includes a controller embedded in a polymeric material configured for mounting to a surface of an eye. The controller is electrically connected to an antenna included in the eye-mountable device. The controller is configured to: (i) receive an indication of an interrogation signal via the antenna, (ii) responsive to the interrogation signal, output a substantially unique identification sequence; and (iii) use the antenna to communicate the substantially unique identification sequence. The substantially unique identification sequence can then be used by external readers to associate the eye-mountable device with device-specific information without storing such information on the eye-mountable device.
