The document describes The Car Wash Crew, which provides car washing services to condominium residents using technology. It sends proposals to condominium managers and invites residents to register via its website. Registered customers receive RFID tags to place on their windshields so the crew can identify their cars. The crew uses RFID readers to spot registered cars and scans them before washing. A backend system tracks when registered cars enter and exit to send status updates to customers by text.
