Abstract: Radio Frequency Identification (RFID) technology uses radio frequency to track or detect objects using tags and readers. This is similar to the barcode detection but barcode detection requires the object to be in the line of sight. Due to the wireless nature of RFID, we find its use in various applications such as in retail management, healthcare, toll stations, postal service and many other areas. However, RFID has various problems and concerns associated with it. This paper focuses on some of the issues seen in retail management. The paper also provides a handful solution to counter some of these issues. After considering some of these solutions, the paper provides us with ideal RFID network that can be use in day-to-day life. …show more content…
Active tags are also referred to as smart tags, as they can initiate communication by themselves. However, they are the most expensive tags and are only used in critical area. BAP also has an in-built battery but it is activated by a RFID reader that supplies power to the tag. An RFID reader is managed by a computer system that stores databases of all RFID tags. It alerts in case if a product goes out of stock. RFID readers are of two types: Fixed and Mobile. Fixed RFID readers capture tags at a static location. For example, we find fixed readers at the entrance of a departmental store. Mobile readers are movable readers that can track objects on the move. We can find a mobile reader in a manufacturing plant that capture moving devices moving in the process of production. [2]

2. Advantage of RFID system over barcode system

i. Automation: RFID system automates the management of goods. We need require man-power who needs to continuously monitor the system as in a barcode system. ii. Cheap: With the rapid advancement in miniaturization, the cost of RFID tags has reduced significantly. Today, the cost of a RFID passive tag is as low as 5 cents/tag.[12] iii. Reliability: RFID readers provide a read rate of more than 98%. Even barcode detection which is done manually is not 100% accurate [13]. Barcode detection is more prone human errors and hence is not reliable. iv. No line-of-sight required: An RFID tag does need to be in the line of sight of
