Radio Frequency Identification Device(RFID)
3. What is RFID?
RFID stands for Radio Frequency Identification
Device. It is an automatic identification
technology whereby digital data encoded in
an RFID tag or Smart label is captured by a
reader using radio waves.
RFID is a wireless communication technology
that is used in physical markers (RFID tags) to
mark products
Question 1
RFID
What is RFID?.
4. RFID
RFID systems consist of three basic
components:
A tag (also called a transponder),
An interrogator (a reader or a
read/write device) and
A controller (a host).

5. 3.What are the main parts of RFID?
RFID tags consist of an integrated circuit (IC) attached to an
antenna.
Data is stored in the IC and transmitted through the antenna to a
reader.
RFID tags are either Passive(no battery) or Active(self-powered
by a battery). Tags also can be read-only(i.e. stored data can be
read but not changed) or read/write (stored data can be altered or
rewritten), or a combination, in which some data is permanently
stored while other memory is left accessible for later encoding
and updates.

6. 4.Describe the working procedure of
RFID.
A reader is basically a Radio Frequency (RF) transmitter and receiver,
controlled by a microprocessor or digital signal processor.
The reader captures the data from tags with help of antenna, and then
transfers the data to computer for processing.
Readers can be affixed in a stationary position (for example, beside a
conveyor belt in a factory or dock doors in a warehouse) or portable
(integrated into a mobile computer that also might be used for scanning
bar codes).
The reader in turn sends the data to the processor and determines the
actions to be performed.
Once the process is over, the processor sends an acknowledgment
signal to the tag stating the completion of the operation.

Product Tracking System
In spinning industry it is used to avoid product mix, which is one of
the prevailing problems faced in the quality control department.
The areas such as carding, drawing and combing (sliver can hank
mix-up), simplex (bobbin mix-up), ring spinning (cop mix-up)
can be avoided by placing the tag in the corresponding semi-
finished materials.

apparel industries
Tracking of Labor Movement
Knowing where an employee is at a particular time would allow the management
to dispatch the closest-qualified employee to a location requiring assistance. If
an RFID reader detects an RFID-tagged employee approaching a security door,
the door could be designed to open automatically. This would allow employees
carrying packages or carts to move more efficiently. Additionally, if store
management could verify through an automated system that an employee was
at the appropriate station at the start of the shift or end of a break, some aspects
of labour management could be automated, requiring less effort by employees
and the management.

Fabric Lot Storage and Retrieval
Due to limited machine capacity in a wet processing unit, a fabric order
may require many number of lots, each lot will be having their own
shades. In this process there have many advantages in RFID.
Firstly, the process of fabric stock-taking in stockrooms is much more
effective.
Secondly, the effectiveness of all production and storage processes is
higher. Moreover, it enables tracking a given object at every stage of its
production process.
Finally, Griva achieved a return on its RFID investment within nine
months.

Garment Washing and Laundering
The normal RFID tags are not launderable and also it is not possible to tag the
garment using barcodes in the process of washing and laundering. For this
purpose, a German company which makes RFID tags, KSW Microtec, has
unveiled two new labels. One can be ironed or sewn directly onto the fabric of a
garment. The other is mounted on a polyester substrate and sewn onto a garment.
The new flexible 13.56 MHz labels can withstand temperatures of up to 40C.

Merchandise Leveling Across Stores
Some stores require customers to leave merchandise that they are
carrying at a desk or provide evidence of purchase. However, if a
store has RFID readers and RFID-tagged merchandise, shoppers
could avoid this step. Instead, at checkout, the readers would
charge customers only for items with tags that indicate that they
were not already paid for.

Easy Product Accessibility in Retail Stores
By using RFID, shop sellers can identify the exact location of any retail item
at any time. Customer requests can be handled quickly and easily by your
customer service team through access to a centralised database. RFID-tagged
items offer store-to-store visibility, so items can be located immediately with
the touch of a button. This level of product accessibility results in shorter
wait times for customers and offers a better shopping experience. Improving
overall store efficiencies ultimately results in greater savings to customers.

Exchange Goods Inventory Control
When any apparel product is returned or exchanged, its RFID tag
could be read and automatically added to the inventory database.
Employees who do re-stocking could read the RFID for returned
items; they could be given information about where to place them
(that is, the appropriate shelf if the item is not defective, or a
particular area in shipping for returning to the vendor if the item
is defective). An application could automatically compare the
RFID code of the returned item against recall notifications.

Customer-Specific Shopping Reminders and Promotions
With RFID on loyalty cards to identify the customer, and a customer shopping-
history database, items could be priced differently depending on the
characteristics of the shopper (eg, special promotions for first-time shoppers
and rewards for frequent shoppers). Different promotions could be offered to
different customers via their personal digital assistants or cell phone displays,
at kiosks (Information Booth), and by employees receiving price on their point-
of-sale terminals. Additionally, if customers have submitted their profiles to the
store, they could be reminded of upcoming events such as birthdays, and have
purchases suggested to them. These can be added on to the loyalty cards which
already exist at places like Shopper’s Stop, Wills Lifestyle, etc, and it can be
centralised to all the stores in different cities so that customers get similar
welcome whether they are in dhaka or london or new york.

Re-Stocking Alerts and Replenishment
Products are monitored to ensure that they remain stocked at
appropriate levels. When they fall below that level, an alert
is sent to the stockroom or office to bring out or order more
merchandise. For stores with stockrooms, RFID monitoring
alerts employees when stock levels reach the threshold. For
example, if many black trousers of waist 32-size are being
sold and are getting out of stock, RFID can send an alarm to
order more such trousers from the storeroom.

Efficient decision making: A study of the processes of
production and the pattern of sales can be done using the data
collected by employing RFID. Unnecessary processes can be
identified and eliminated. If any process is taking more time than
it should, the reasons behind it can be determined and problems,
if any, can be eliminated. Similarly, if the demand for any product
is very less, a decision might be taken not to stock it at all or to
stock it in a lesser quantity. Hence, RFID is also helpful in
making efficient decisions, ultimately saving cost and increasing
the profitability of the organization.
17Q16.How RFID helps in decision making?
18. The applications of RFID in textile and

Ease in inventory control: Accurate data about all the material
that comes into a warehouse and goes out of is available through
the use of RFID. Similar is the case with a retail outlet. Hence,
stock can be replenished as soon as it is exhausted. Out-of-stock
situations can be reduced, thereby increasing customer
satisfaction and trust on the outlet.
Similarly, keeping track of capital assets also becomes simpler, and
their management also becomes easier and more effective.
18Q17. How RFID makes easy in inventory control?
19. The applications of RFID in textile and
apparel industries
Reduction in supply chain errors: RFID can be used to track
the movement of the goods that go out of warehouses. In this
case, as soon as a certain goods item goes astray on the way from
the warehouse to the place of production, information about the
same can immediately be obtained at the point of control.
Wastage and theft can thus be minimized, and the possibility of
errors in the supply chain can be brought down drastically. This,
in turn, would lead to timely completion of the production
process and savings in cost.

Lesser human intervention: When RFID is incorporated in an
organization, the necessary data can be collected as and when
required using a reader. The number of people required for
locating lost goods, for finding a certain product, as well as in
inventory control and management can be reduced. RFID leads to
lesser requirement of human intervention, which, in turn, leads to
considerable savings in manpower costs.

Efficient quality control: RFID helps in obtaining data about the
exact time when each component of the process of production
passed on to the next stage. In case of any defect in a certain
batch at a later stage, it would be possible to trace it back to a
particular worker or group of workers. Quality control thus
becomes more efficient.
Similarly, good work done can also be traced back to the concerned
worker or group of workers. They can be rewarded accordingly.
This would, in turn, boost the morale of the workers.
