PP: What I can’t quite grasp is how [the ink] retains a unique code or pattern.
Pydynowski: While we say that it’s an RFID ink, it has the same functionality as RFID. However ... we’re completely chipless—there’s no integrated circuit and we’re purely an ink. How that ink retains a unique ID is [through] the pattern in which the ink is encoded. ... We encode that pattern with a micro-needle array ... of many, many small needles, and you can use them to basically deposit a unique pattern. Some people, in terms of understanding it, can think of it conceptually as you think of a regular bar code, or a 2-D bar code ... . That’s a unique pattern. Conceptually, we’re very similar to that, but very different ... [the bar code] actually relies on line of sight to be able to read it, where you don’t need to see ours—you can actually read through the [livestock’s] hair.
