Abstract
A radio-frequency identification (RFID) tag includes circuit elements that result in a resonant frequency that differs from the excitation frequency of an RFID reader. The RFID tag, when stacked with other similar RFID tags, channels the magnetic flux density field (B-field) through the stack to power each of the tags in the stack. As a result, the B-Field is collimated in a manner that increases the sensitivity (read range) in one dimension (up a stack of chips) while simultaneously limiting the sensitivity in the two lateral dimensions, thereby providing precise spatial resolution of each tag as to its location on a gaming table.
