To ensure the success and sustainability of your self-service kiosks and RFID systems, you should involve your users and staff in the planning, testing, and launching of your solution. Make sure to provide clear and consistent instructions on the kiosk screen, signage, or brochures. Additionally, you should maintain and update your solution by performing regular maintenance, cleaning, and troubleshooting. Furthermore, it is important to update software, firmware, or content as needed and replace or repair any faulty or damaged components. By doing so, you can ensure that your users and staff know how to use your solution and what to do in case of problems or errors. Offer multiple channels of support such as phone, email, or chat to address their concerns and questions while recognizing their contributions and achievements.
