Midterm Study Guide
General Information about the Exam
• Multiply choice.
• ~ 35 questions.
• I think that immediately after graduation most of you will work at jobs requiring
hands-on experience and technical knowledge rather than strategic managerial
perspective. Therefore, most of the test questions deal with technical and
practical information. There are not too many questions involving managerial
perspective on RFID technology.
• I stressed certain points in class and repeated these points several times and just
skimmed through what I thought were less important points. If you can recall
what I stressed from your memory or retrieve this information from your notes,
you will have a better idea on what to concentrate for the test.
Preparing for the Exam
I suggest that you do the following to adequately prepare for the exam (in the order of
1. Read all of the lecture slides. Make sure you have a good understanding of every
slide that was shown in class. If you don’t understand something, you can do one
of the following (with the first option being the best, in my opinion)
a. Ask me
b. Read the additional reading materials posted for that particular class.
While this is not required, it can shed some light one areas you don’t quite
c. Ask your classmates
Most of the questions in the test are based on slides.
2. Read the following papers:
b. RFID tutorial from CAIS
c. Paper on characteristics of RFID Systems by AIM Global
d. RFID Glossary
I would say that at least 50% of the test questions are based on the information
found in these three papers (either directly or indirectly). Probably all of the
information found in these papers can also be found in slides. However, I think
that these readings will give you a better understanding of the slides.
Again, if you have any questions about the information contained in this papers,
please do not hesitate to ask me.
3. Watch the videos that were shown in class. I suggest that you watch (or watch
again) at least the following video:
a. Video presentation on physics of RFID by Matt Reynolds, ThingMagic
Only a few questions are based on this video. However, as you probably know
from your past experience, a few correctly answered questions can make a big
difference. You may also review the slides that come with each if these videos.
If you are really short on time, I would suggest reading slides only. However, this would
be a bare minimum. I don’t think you are likely to get a good grade by only reading the
Regardless of the strategy that you choose, be ready to answer the questions listed below.
1) What is Auto-ID?
2) Which technologies are usually considered to belong to the Auto-ID family?
3) How is information encoded with the help of barcodes?
4) What kind of information can be encoded with the help of barcodes?
5) What are some of the fundamental characteristics of barcode symbologies?
6) Why would an organization choose one barcode symbology over another?
7) Which factors make a barcode symobology more reliable in terms of the percentage
of no-reads or false reads?
8) When would a company want to use RFID instead of barcodes?
9) What are smart cards?
10) What is biometrics?
11) How do biometrics technologies differ? (Please study Table 1 found at the end of this
12) Know some of the most important aspects of RFID history prior to its entrance to the
13) Which organizations were the most influential endorsers of RFID?
14) What are the elements of RFID system architecture?
15) What are some of the most important characteristics of tags?
16) What is frequency? How is it important to RFID system performance?
17) What are 1-Bit Transponders?
18) What is operating range? What factors influence the range?
19) What is the difference between active and passive tags?
20) What are the most common frequency bands used in RFID?
21) You should know that waves of different frequencies behave differently with respect
to material propagation. For example, at some frequencies, signal cannot pass through
water or substances that have high water content. A number of questions are based on
understanding the physics behind RF waves.
22) What are some of the most popular physical forms of tags?
23) What is diffraction? Refraction? Reflection? Absorption?
24) What are the procedures for transmitting date between a tag and a reader? (hint: “-
25) What advantages can be potentially achieved with the help of RFID in retail
26) How does TAVIS Concentrator LI work?
27) Know some of the most important characteristics of our RFID hardware
28) What is the central law in Physics governing data and power transmission in RFID
29) What is Silent Commerce?
30) What is EAS?
