Hello, I'm Johnuniq. An edit that you recently made to Radio-frequency identification seemed to be a test and has been removed. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! Johnuniq (talk) 08:38, 26 February 2020 (UTC)
