Abstract: A method for harnessing a connected network to securely verify and execute a transaction is provided. The method may include requesting a PIN from a mobile device. The request may be transmitted via a USSD message. The method may also include receiving the PIN from the mobile device. The PIN may be received via a response to the USSD message. The method may also include authenticating the mobile device. The method may also include accessing a third-party network to verify an authentication status of the mobile device. The third-party network may include a plurality of IoT endpoints. Each IoT endpoint may include a stored verification usage process. The stored verification usage process may relate to a user associated with the mobile device. The method may also include executing the transaction upon receipt of an authentication signal from the third-party network.

Abstract: A photoelectric sensor that eliminates close range detection blind areas without shortening the detection distance. The photoelectric sensor includes a current-limiting resistor and a photoelectric diode connected in series for converting an optical signal to an electric signal for use. Two ends of the current-limiting resistor are connected in parallel with at least one shunt branch. The shunt branch includes a shunt resistor and a switch circuit connected in series. The switch circuit is switched on when the voltage across two ends of the current-limiting resistor is greater than a predetermined voltage value depending on the shunt branch and is switched off when the voltage across two ends of the current-limiting resistor is less than the predetermined voltage value.
