Tagged refers to a method of marking a stamp so that automatic mail machines can work with a letter. Early trials included graphite lines on the back of stamps. Today, most stamps are tagged with a phosphorus ink that is transparent and printed over the stamp design. Ultraviolet lights can detect them and allow the envelopes to be oriented to enable automatic cancelling machines and sorting machines to do their work.
