System for event-driven delivery of digital offers to customers while inside a car wash

1 . A computer-implemented method for engaging with a computing device of a user of a car wash having a plurality of wash operations, the method comprising:

providing a machine-readable code via a point-of-sale terminal of the car wash, the machine-readable code configured to cause computing devices to transmit a) a respective session ID and b) at least one of i) a respective device identifier or ii) a respective cookie identifier to a remote server upon scanning of the machine-readable code;

receiving, by the remote server and in response to the computing device of the user scanning the machine-readable code, a) a session ID, and b) at least one of i) a device identifier or ii) a cookie identifier associated with the computing device of the user, thereby linking the computing device of the user to the remote server;

receiving, by the remote server, an input signal corresponding to an input from the user, the input signal comprising a subset of wash operations of the plurality of wash operations;

for each wash operation of the subset of wash operations, determining, by the remote server, an associated digital offer element;

sequentially detecting, by a programmable logic controller (PLC) at the car wash, activation of each car wash operation of the subset of wash operations via one or more sensors, electronic relays, and/or switch closures of the car wash;

sequentially transmitting, by the PLC and to the remote server, an indication of activation of each wash operation of the subset of wash operations; and

upon receiving each sequentially transmitted indication of activation of each wash operation from the PLC, transmitting in real time, by the remote server and based at least in part on the session ID and one of i) the device identifier or ii) the cookie identifier, the determined associated digital offer element corresponding to the wash operation to the computing device of the user.

2 . The method of claim 1 , wherein the plurality of wash operations comprise a pre-wash operation, a foam application operation, or a high-pressure water blasting operation.

3 . The method of claim 1 , wherein the remote server receives the input signal from the point-of-sale terminal.

4 . The method of claim 3 , wherein the machine-readable code comprises a quick-response code (QRC) at the point-of-sale terminal of the car wash.

5 . The method of claim 4 , wherein the car wash is an in-vehicle car wash.

6 . The method of claim 5 , wherein the in-vehicle car wash is unattended.

7 . A system for engaging to a computing device of a user of a car wash having a plurality of wash operations, the system comprising:

one or more sensors, electronic relays, and/or switch closures of the car wash;

a programmable logic controller (PLC) at the car wash, the PLC in communication with the one or more sensors, electronic relays, and/or switch closures, the PLC configured to:

sequentially detect activation of each car wash operation of the plurality of wash operations via the one or more sensors, electronic relays, and/or switch closures of the car wash; and

sequentially transmit, to a remote server, an indication of activation of each detected wash operation;

a quick-response code (QRC) provided by a point-of-sale terminal at the car wash, the QRC configured to cause computing devices to transmit at least one of i) a respective device identifier or ii) a respective cookie identifier to the remote server upon scanning the QRC; and

the remote server, wherein the remote server is in communication with the point-of-sale terminal, the PLC, and the computing device of the user over at least one communication network, the remote server configured to;

receive, in response to the computing device of the user scanning the QRC, at least one of i) a device identifier or ii) a cookie identifier associated with the computing device of the user, thereby linking the computing device of the user to the remote server;

receive an input signal corresponding to an input from the user, the input signal comprising a subset of wash operations of the plurality of wash operations;

determine, for each wash operation of the subset of wash operations, an associated digital offer element;

sequentially receive, from the PLC, an indication of activation of each wash operation of the subset of wash operations; and

transmit in real time, upon receiving each sequentially received indication of activation of each wash operation of the subset of wash operations from the PLC and based at least in part on one of i) the device identifier or ii) the cookie identifier associated with the computing device of the user, the determined associated digital offer element corresponding to the wash operation to the computing device of the user.
