Controlled dispensing system and method

Abstract

An electronic device comprising: one or more processors; a radio transceiver; memory storing a unique serial number identifying the electronic device; pairing circuitry configured to communicatively couple, using the radio transceiver, the electronic device with an external device distinct from the electronic device; first electronic circuitry configured to perform a plurality of operations of the electronic device; and activation circuitry configured to activate and deactivate the first electronic circuitry; wherein the memory stores instructions that, when executed by the one or more processors, cause the one or more processors to (i) detect, using the pairing circuitry, a successful pairing of the electronic device with a first external device; and (ii) in accordance with the detection of the successful pairing, activate, using the activation circuitry, the first electronic circuitry.
