An RFID-based power meter and outage recording system

Radio frequency identification (RFID) is looked upon as one of the top ten important technologies of the twentieth century. In coming years, public area applications are the key issue in developing RFID. Power systems are innately bulky, large, and definitely, an extremely important application area for RFID. In power areas, RFID has great potential to be applied extensively to customers. Therefore, an RFID-based power meter and outage recording system is proposed in this article. The proposed system can be used to fully collect and record power consumption data and power reliability information on customers. A small-scale power meter and outage recorder is designed first and then an RFID system is designed and embedded into the power meter and employed to record the power data in tags. A handheld meter management system is also designed in this article to collect the data stored in the tags and synchronize the collected data with rear-end processing if necessary. Due to the uniqueness of RFID tags, the power consumption data and outage information on customers can be recorded and then identified in a rear-end processing system. Experimental results show the validity of the proposed system.

RFID tag readability issues with palletized loads of consumer goods

Radio Frequency Identification (RFID) is an automatic identification technology, relying on storing and remotely retrieving data using devices called RFID tags. This technology is being used in enterprise supply chain management‐related applications to improve the efficiency of inventory tracking and management. However, this technology has not been able to realize its promised potential because of several factors, such as lack of congruous worldwide standards, privacy issues and less than perfect read rates in supply chain applications. This research aimed to evaluate the readability issues commonly faced by tagged cases of palletized consumer products. The variables studied in this research were product‐package type, tag type, tag location on cases, pallet pattern and forklift speed through a RFID portal representative of a dock door in a warehouse. To determine which variables were the most significant, a binary logistic regression was run. The number of tags read was inputted for the number of events and total number of products per pallet as the number of trials. The variables product content, pallet pattern, and speed, and all interactions were then included in the model. It was observed that readability greatly varies for different product‐package systems, with paper towels producing near‐perfect reads, followed by bottled water and carbonated soda cans. The slower the forklift truck speed, the better the readability across the board, and the best pallet patterns were dependent on the product‐package type. For bottled water, the best pallet pattern was column, and for carbonated soda, the interlocking pattern. Copyright © 2009 John Wiley & Sons, Ltd.

RFID research and testing for packages of apparel,consumer goods and fresh produce in the retail distribution environment

Radio frequency identification (RFID) is a term used for any device that can be sensed at a distance by radio frequencies with few problems of obstruction. The origins of the term lie in the invention of tags that reflect or retransmit a radio‐frequency signal. According to a recent article by Forrester Research, the minimal ‘Slap and Ship’ approach to RFID compliance will cost an individual company between $2 million and $20 million. Because retailers like Wal‐Mart plan to share with their suppliers all the RFID‐generated data points (from when a case/pallet enters their distribution centre until it leaves their stockroom), suppliers will eventually be able to use this data as a powerful forecasting tool. RFID is an enabling technology that can potentially facilitate a real‐time, end‐to‐end supply chain visibility system. Suppliers who integrate full‐scale RFID systems will realize efficiencies in time, material movement, inventory planning, shipping and warehousing both internally and externally. This paper provides a brief overview of the RFID technology, mandates by retailers and federal agencies, advances towards global standardization and typical consumer level RFID applications, and discusses RFID initiatives taken by some of the global leaders in apparel, consumer goods and fresh produce industries.

Invisible computing: automatically using the many bits of data we create

As we go about our work and our daily lives, we leave a trail of bits behind. Every electronic device we interact with can keep a record of our actions. Even the devices themselves can keep track of their location and radio interactions, even without user involvement. The challenge of invisible computing is to make this wealth of data useful. This paper presents two examples of what has come to be known as 'invisible computing', namely, devices recording, distilling and rendering these many bits of data without unduly taxing human users. The first example is focused on a work environment. Labscape automates the record keeping required of experimenters in a cell biology laboratory. The second example looks at more ad hoc interactions. RFID Ecosystem is a collection of radio-frequency identification (RFID) readers and databases that collect the sightings of passive RFID tags, attached to people and objects, as they move throughout a large building. It provides services such as people and object finding as well as diary keeping.
