Kiosk Requirements

To take advantage of the LPR technology, you must have the following:

  • 3.2.14 - 3.3.X and above in Commander/HTK3/CTK3 > Supports LPR Configuration + Kiosk Sign Up

Kiosk Set-Up

Most of the heavy lifting for LPR actually occurs within Hosted Solutions. To make sure that the LPR camera can communicate to the kiosk, follow the LPR manual to confirm communication and proper installation. You can check the manual here.

Once you have confirmed that the LPR camera is communicating with the kiosk, make sure that the kiosk can communicate with Hosted Solutions and that the system works properly.


To make sure that the HTK/CTK is configured correctly, log in to your Kiosks programming side. It is assumed in this article that you already have the credentials to login and are familiar with the HTK/CTK programming screen.

Kiosk Sign up Settings

If the HTK/CTK or Commander kiosk has software version 3.2.14 - 3.3.X or above, the controller supports both the above LPR configuration as well as the Kiosk Sign Up feature. This allows the kiosk to capture contact information and payment information from a customer to enroll them into a monthly wash club. The average app user has already been using wash clubs via a sign up process within the app. Now a non app user may pull up to the kiosk and be presented with the option to sign up for a wash club. the process for this is as follows:
