I'm sorry. This page requires that your browser be capable of running JavaScript in order to use the self-correcting feature of the quiz. In most browsers you can activate JavaScript using a dialog box somewhere under one of the menu bar options. If you are really using a (rare) non-JavaScript-capable browser, you will have to do without the self-grading features of this page.

Instructions: Answer the multiple choice RFID questions, guessing if necessary; then click on the "Process Questions" button at the end of the RFID training assessment to see your score in the adjacent message box. The program will not reveal which questions you got wrong, only how many points you have. Go back and change your answers until you get them all right or take our online RFID course.

(The message box will rejoice at 100% correct and the page may change color in delight.)

Points to note: (1) FRID Questions have only one possible answer are one point each. (2) The program will not attempt to score your efforts at all if you have not tried at least half of the questions. (3) This free technology assessment is for your own use only. No record of your progress is kept or reported to anyone.
