Encoder receiver transmitter (ERT) is a packet radio protocol developed by Itron for automatic meter reading. [1] The technology is used to transmit data from utility meters over a short range so a utility vehicle can collect meter data without a worker physically inspecting each meter.
A "smart pill" is a relay which can be added to an electrical circuit to turn on or off one or more appliances, like lights or solar screens. Smart pills can for example be controlled via an app, a wireless switch and/or a conventional push switch .

Insteon is an integrated dual-mesh (formerly referred to as "dual-band") network that combines wireless radio frequency (RF) and a building's existing electrical wiring, [7] in which all devices are peers and each device independently transmits, receives, and repeats messages.
RF smart card schematic. A contactless smart card is a card in which the chip communicates with the card reader through an induction technology similar to that of an RFID (at data rates of 106 to 848 kbit/s). These cards require only close proximity to an antenna to complete a transaction.
