The study, Development of Price Item Calculator Using Barcode Technology, aims to
help senior citizen, person with disability and price conscious consumer in terms of
shopping and budgeting. They encounter problems such as a malfunctioning price verifier
and products that do not have tag prices. These situational factors affect the buyer's time
management and their budgeting schemes that leads to price miscalculation. The price
item calculator is capable of checking and calculating the total price of the items bought
by the consumer. The total price can be classified into two: the discounted price for
persons with disabilities and senior citizen, and the original price for ordinary consumers.
The Raspberry Pi with its program written in Python language serves as controller of the
hardware connected to it and it also serves as processor of the scanned items. The
database which consists of the item price and description can be updated through flash
disk drive. The project was evaluated by 25 evaluators consisting of sari-sari stores
owners, senior citizens, ordinary consumer and those who are knowledgeable in
electronics and information technology inside and outside the TUP-Manila campus and
garnered a rated overall mean score of 4.19 with a descriptive rating of "VERY
ACCEPTABLE". This proves that the price item calculator is a helpful innovation for the
consumers in knowing the price due of the grocery items that they will buy before paying
at the cashier.
