The document outlines a proposed smart shopping trolley system that utilizes RFID technology to streamline the shopping process and reduce customer waiting times. This system allows customers to scan items as they add them to their trolley, with the total cost displayed in real-time, enhancing the shopping experience. The document also discusses the components required for the system, including hardware and software, along with potential applications and advantages of implementing this technology in retail environments.

3.  At present, we are using the process in malls with help of barcode
scanner. Vendor scan the product through the barcode scanner. This
is to be a slow process and Customer has to wait for long queues. So,
this is a one of the reason for most of the people want to leave the
mall for waiting a long queue to buy a few products.
 To avoid that, we want to buy more products recent years have been
introduced new type of technologies. customer has to put a product
into smart shopping trolley. Each and every product has product id.
The RFID reader can read the product id. Which can have been useful
for customers. All such solutions can be useful for customer. Such
solutions save the customer time and money etc….

4.  A customer goes into a shopping center then she/he first take a
trolley. Every last trolley is joined with a scanner tag per user and a
RFID per user. The framework work is the point at which the
customer buys a thing, the customer must be examining the thing
first with help of standardized tag are available in each item utilizing
the RFID per user.
 At that point that acquired thing can be set into the trolley. While the
client is examining the RF tag of the item, a cost of the buying item
is taken and spared in the framework's memory/Arduino.
Information put away in framework's memory is contrasted and the
query table. In the event that matches are discovered at that point
cost, name of individual item gets showed on the LCD.

11. Tags can be attached to almost anything:
◦ Items, cases or pallets of products, high value goods
◦ vehicles, assets, livestock or personnel
Passive Tags
◦ Do not require power – Draws from Interrogator Field
◦ Lower storage capacities (few bits to 1 KB)
◦ Shorter read ranges (4 inches to 15 feet)
◦ Usually Write-Once-Read-Many/Read-Only tags
◦ Cost around 25 cents to few dollars
Active Tags
◦ Battery powered
◦ Higher storage capacities (512 KB)
◦ Longer read range (300 feet)
◦ Typically can be re-written by RF Interrogators
◦ Cost around 50 to 250 dollars

12.  Read-only tags
◦ Tag ID is assigned at the factory during manufacturing
 Can never be changed
 No additional data can be assigned to the tag
 Write once, read many (WORM) tags
◦ Data written once, e.g., during packing or manufacturing
 Tag is locked once data is written
 Similar to a compact disc or DVD
 Read/Write
◦ Tag data can be changed over time
 Part or all of the data section can be locked

13.  Reader functions:
◦ Remotely power tags
◦ Establish a bidirectional data link
◦ Inventory tags, filter results
◦ Communicate with networked server(s)
◦ Can read 100-300 tags per second
 Readers (interrogators) can be at a fixed point such
as
◦ Entrance/exit
◦ Point of sale
 Readers can also be mobile/hand-held

14.  A DC motor is an electric motor that runs on DC electricity. It
works on the principle of electromagnetism. A current carrying
conductor when placed in an external magnetic field will
experience a force proportional to the current in the conductor.
They are various methods used to control the speed of a DC
motor. Some of them are:
1. Armature control method
2. Flux control method
3. Ward Leonard system

15.  The MAX232 is a dual driver/receiver that includes a capacitive voltage
generator to supply EIA-232 voltage levels from a single 5-V supply. Each
receiver converts EIA-232 inputs to 5-V TTL/CMOS levels. These
receivers have a typical threshold of 1.3 V and a typical hysteresis of 0.5 V,
and can accept ±30-V inputs. Each driver converts TTL/CMOS input levels
into EIA-232 levels.

16.  GSM modem is a specialized type of modem which accepts a SIM card, and
operates over a subscription to a mobile operator, just like a mobile phone.
From the mobile operator perspective, a GSM modem looks just like a mobile
phone
 When a GSM modem is connected to a computer, this allows the computer to use the
GSM modem to communicate over the mobile network. While these GSM modems are
most frequently used to provide mobile internet connectivity, many of them can also be
used for sending and receiving SMS and MMS messages.
 .

17.  The Arduino Uno can be programmed with the Arduino software.
Select "Arduino Uno from the Tools > Board menu (according to the
microcontroller on your board).For details, see the reference and
tutorials. The ATmega328 on the Arduino Uno comes preburned
with a boot loader that allows you to upload new code to it without
the use of an external hardware programmer. It communicates
using the original STK500 protocol (reference, C header files).We
can also bypass the boot loader and programs the microcontroller
through the ICSP (In-Circuit Serial Programming) header; see these
instructions for details. The ATmega16U2 (or 8U2 in the rev1 and
rev2 boards) firmware source code is available. The
ATmega16U2/8U2 is loaded with a DFU boot loader, which can be
activated by:
 On Rev1 boards: connecting the solder jumper on the back of the
board (near the map of Italy) and then resetting the 8U2.
 On Rev2 or later boards: there is a resistor that pulling the
8U2/16U2 HWB line to ground, making it easier to put into DFU
mode.

18.  It saves customers time.
 It also reduces the payoff given for
workers.
 It is possible to rewrite the RFID tags.
 It doesn’t need line of sight.

19.  It Can be utilized in dress
showrooms
 Grocery store
 All wholesale shopping malls

20.  The desired objectives were successfully achieved in the prototype
model developed. The developed product is easy to use and
economical. Though the project showcases the proof of concept,
there are a few aspects that can be included to make the smart
shopping cart more robust. To begin with, in this project the latency
time of the wireless communication with the server may need to be
considered. Secondly, the communication is not very secure.It is
impossible to stick RFID tag to some products. In such cases,
conventional scanning of barcode is more sophisticated. Further, a
more sophisticated micro-controller and larger display system can
be used to provide better consumer experience.

21.  Contingent upon the RFID peruser utilized, it could peruse around 7 labels
in a second. What's more, the real errand of keeping away from the
perusing of a similar label on numerous occasions has likewise been
practiced by actualizing a peaceful label work. At last the charging is
finished in almost onetenth of the time required in standardized tag based
charging framework incorporating the time required in dispatching the
things which incorporate expelling of labels from the things. Further, in
future we can anticipate actualizing it in shopping centers utilizing a long
range RFID peruser (with a scope of ~2metres). 1. The utility of trolley are
first of its sort for modern use. 2. This gadget records the data of the
different item with encourage of the worthy sensors like RFID Tags. 3. This
recorded data helps the inquiry proprietor with cautious examination of
shopping by the customer and their inclinations through the PC; yield sign
of a comparative might be acquired. 4. Net banking can be incorporated. 5.
Utilizing a GSM module we can move the bill to portable as opposed to
printing it. 6. Voice help can be incorporated. 7. Mechanical ARM might be
utilized for choosing and dropping of item
