at least partially indicative of a sticker identity and the object type,
the method including, in a computer system: receiving indicating data
from a sensing device, the indicating data being at least partially
indicative of the identity of the sticker and the object type, the
sensing device, when placed in an operative position relative to the
sticker, being responsive to sense at least some of the coded data and
generate the indicating data using the sensed coded data; identifying,
using the indicating data, the identity of the sticker, the object type
and the object of the object type; and, generating an association based
at least partially on the sticker identity and the object.
