Capacitive coupling (Glossary of Printed Electronic terms)

Contactless signal transmission by electrostatic effect, i.e. the capacitance of the (small) gap. A minority of contactless chip cards and tags use this principle, notably Motorola BiStatix process licensed to DNP, Flint Ink, Power Paper, etc and Cypak technology used in patient compliance monitoring blister packs.
