A device stores one or more compression rules for an action language. Upon
receipt of a signal from a tag (such as an RFID tag, a visual tag, or an
audio tag), a compressed data stream corresponding to the tag is decoded
from the signal. Based on the one or more compression rules, one or more
action parameters are derived from the compressed data stream. With these
parameters, a corresponding action is performed. The action may include
communicating across a wireless communications network as well as
obtaining content from a remote content provider. Also the action may
include storing data, such as a contact entry, or a calendar event.
