Hello, I'm 49ersBelongInSanFrancisco. I wanted to let you know that one or more of your recent contributions to Radio-frequency identification have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. Thank you. 49ersBelongInSanFrancisco (talk) 05:09, 22 March 2022 (UTC)
