Portable Device for Stock Identification System (PDSIS)

摘要

A current technology storage management system has an obvious weakness in the terminal data gathering because they contain no feature of real-time and automatic data retrieval. Store staffs have to check detail information manually or through the barcode system. Hence, human error may frequently happen due to incorrect information to the stock control or management control. Therefore, it is essential to propose an assistive system with instant information was developed. Radio Frequency Identification (RFID) will be the best solution to overcome the limitation because it is a wireless technology which works by transmits via radio waves and not function in the sense of light. Base on study conducted, a Portable Device for Stock Identification System (PDSIS) is invented to identifying items or stock information by applying RFID technology. This device is developed with display system as user indicator to print out item information read from database and keypad input for data retrieval into memory storage. This device also developed for handheld features which is has medium size that portable to the user to bring anywhere without limitation. A few analyses were conducted based on the endurance testing in term of performance, accuracy and efficiency. In summary, this automatic portable device helps user to identify items for stock management in a short time instead limitation of manual method.
