The international community is at a cross-roads, keep allowing counterfeit medicinal drugs, or create legislation that prevents that from happening in the future. The legislation has been created, so how will you ensure compliance?
GPR systems work by sending a tiny pulse of energy into a material via an antenna. An integrated computer records the strength and time required for the return of any reflected signals. Subsurface variations will create reflections that are picked up by the system and stored on digital media. These reflections are produced by a variety of material such as geological structure differences and man-made objects like pipes and wire.
This creative and informative presentation gives a great gist about the bare codes, types of bar codes, bar code readers and its type. Also for better understanding, there has been provided the ways to decode it for a leman. This presentation also gives an idea about the advantages and disadvantages as well as it applications in different fields. This is well designed presentation for who are aiming for engineering.
It is a recent development in the field of Computer science, used to encode information within an abstract picture.Even though it provides same level of security as the bar codes, it ensures encoding of more amount of data as compared to the traditional ways of encoding.
Barcode or Barcode Reader is an optical machine-readable representation of data relating to
the object to which it is attached. Originally barcodes systematically represented data by varying
the widths and spacing of parallel lines, and may be referred to as linear or one-dimensional
(1D). Later they evolved into rectangles, dots, hexagons and other geometric patterns in two
dimensions (2D). Although 2D systems use a variety of symbols, they are generally referred to
as barcodes as well. A barcode reader uses a photo sensor to convert the barcode into an
electrical signal as it moves across a barcode. Mechanism: The scanner then measures the
relative widths of the bars and spaces, translates the different patterns back into regular
characters, and sends them on to a computer or portable terminal. If we use barcodes, we get
online information without giving any data to the computer. If the manufacturing company
produces large quantity of products, then these barcodes are very useful.
A QR Code is a two-dimensional bar code that is readable by smartphone or other handheld devices. Information is encoded in both the vertical and horizontal direction, thus holding up to several hundred times more data than a traditional bar code .

There are many different barcodes to choose from, and that make it impossible to implement a barcoding solution. In our latest series we are discussing everything that you need to know about barcoding solutions.
Implementation of 2D Optimal Barcode (QR Code) for ImagesEditor IJCATR
Quick Response (QR) Code is very useful for encoding the data in an efficient manner. Here data capacity in 2D barcode is limited according to the various types of data formats used for encoding. The data in image format uses more space. The data capacity can be increased by compressing the data using any of the data compression techniques before encoding. In this paper, we suggest a technique for data compression which in turn helps to increase the data capacity of QR Codes generated for image. Finally, results are compared with the normal QR Codes to find the efficiency of the new technique of encoding followed by compression for generating optimal QR code.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

3. UPC BAR CODE
The UPC ( A ) bar code symbol, is one of the most
common applications of bar code technology and is
seen on products everywhere.
3
4. HOW THEY ARE
COMMONLY USED
Bar codes are everywhere and they are used to identify
everything from auto parts to hospital patients. The
Universal Product Code is used to identify retail items in
virtually every store and market in the country.

6. UPC (A) BAR CODE GLOSSARY
UPC: Universal Product Code
MODULES: The vertical bars that make up the bar code symbol. Numbers are created by patterns of filled
and unfilled modules. 84 modules are used for digits, and 11 are used for the guards that define the symbols
boundaries.
GUARDS: Left and right guards mark the beginning and end of the symbol and the center guard marks the
division between the manufacturer and product codes.
MANUFACTURER CODE: Is made up of the first six digits and is distributed and managed by the UCC
(Uniform Code Council).
MANUFACTURER IDENTIFICATION NUMBER: Used to identify the particular numbering system used by the
manufacturer.
ITEM NUMBER: Assigned to each product and is defined by the last five digits.
CHECKSUM: A single digit used for error checking.

7. HOW IT ALL WORKS
First, the scanner flashes a laser across the
code reading the lines and spaces across. !
1+3+5+7+9=25
In a fraction of a second the scanner makes
several calculations to determine the
orientation of the code and then error checks
to make certain that the scan was valid. !
!
It does this by testing an algorithm against
the checksum digit.!
7
8. TESTING THE ALGORITHM
0+2+4+6+8=20
20x3=60
1+3+5+7+9=25
First the scanner sums the
digits in the odd positions !
Then it multiplies that !
result by three!
Next, it sums the even !
place digits !
60+25=85
85/10=8R5
10-‐5=5
And adds the two sums!
That result is divided by ten!
The remainder is subtracted from
ten to verify the checksum. If the
checksum doesn’t match, the
scanner reports an error and the
code must be re-scanned.!

9. 2D BAR CODE / DATA MATRIX
Two dimensional bar codes are called so because the reader
scans both horizontally and vertically across the symbol,
unlike linear barcodes.
9
10. HOW THEY ARE
COMMONLY USED
Along with the less popular PDF417 (actually stacked linear)
and Aztec symbologies, Data Matrix is commonly used in
healthcare. Because of its accuracy, efficiency and small
size, it works particularly well on patient wristbands and
medication labels, as it is less likely to distort around curves
and takes up less space, in addition to being highly
readable and accurate.

provide a consistent and reliable
means of labeling small objects.

13. DATA MATRIX BAR CODE GLOSSARY
MODULES: Small square cells that make up the bar code symbol. Usually, dark modules
represent a digital 1 and light represent 0.
FINDER PATTERN: Two adjacent, solid borders are designated the finder pattern. These borders
are used by the scanner to locate and orient the symbol and to correct distortion.
TIMING PATTERN: Two opposite adjacent pair of borders are constructed with alternating dark
and light cells and are designated as the timing pattern. This component gives the scanner
information about the symbol’s size.
DATA REGION: The actual data and error correction information is divided into regions in the
symbol which contain a pattern of modules in a consistent array.
QUIET ZONE: A clear space around the symbol.
13
14. BENEFITS OF THE
DATA MATRIX
VERY EFFICIENT: Misread probability of 1/10.5 million (for the 3 of 9 symbol the probability
drops to 1/1.7 million).
SMALL: Almost 40X smaller than a 3 of 9 carrying the same data.
DEPENDABLE: Error correction capabilities (ECC200 method) allows accurate reads on symbols
with up to 60% damage.
FAXABLE: Data Matrix is also one of the few codes that are faxable. The outstanding capabilities
of ECC200 error correction allows even poorly resolved faxed images to be reliably scanned.
STORAGE CAPACITY: They are designed to encode up to 2335 alphanumeric characters,
though they have a recommended limit of 800 characters, actual best case is around 1200.

15. QR CODE
The Quick Response or QR code is a trademarked two-dimensional
barcode first designed for the automotive industry in Japan in 1994
by Denso Wave, a Toyota subsidiary. Almost a decade ago, it was
introduced to enable high-speed component scanning during the
manufacturing process.
15
16. HOW THEY ARE
COMMONLY USED
Since then QR codes have become ubiquitous, showing
up on product packaging, billboards and bumper
stickers, in magazines and just about any place where
a consumer with a smartphone is likely to seek more
information about any topic, item or idea.

18. QR CODE GLOSSARY
MODULES: square modules arranged on a grid. These modules form the components of the
code. Within the code the modules fall into two categories:
functional and encoding.
FUNCTIONAL MODULES: referring to those pieces that enable accessing the data
ENCODING MODULES: pieces used to store actual data
FINDER PATTERN: These are made up of alternating black and empty modules used to indicate
the position of the symbol’s internal components.
ALIGNMENT PATTERNS: looking much like smaller versions of the positional detection
indicators may occur in several places in the code depending on the code version.
ENCODING PORTION: consists of the information formatting areas and the data and error
correction space.
QUIET ZONE: A clear space around the symbol
18
19. HOW IT ALL WORKS
Data is divided up into code blocks within the data
area, and each code block is sized so that it can
contain no more than 15 errors. This strategy
simplifies the algorithm, and interleaving the data in
the code blocks minimizes the possibility of an
unreadable code due to partial damage to symbol.
This also allows for some artistic license with adding
logos and other simple graphics to QR Codes.
QR Codes can contain four basic types of information:
numeric, alphanumeric, binary and Kanji.
The key to the success of QR Codes lies in the
use of Reed-Solomon error correction.

the physical and virtual worlds.
