TYPES OF RFID
RFID tags are generally classified under two heads: active and passive.
• Active RFIDs have a source of power in the form of a battery embedded in them. This implies they are always active being powered by a constant source of energy. These tags generally have a higher read range and offer read/write facilities. The pitfalls of this are these tags are generally more bulky in size and weight compared to the passive tags (due to the weight of the battery) and are more expensive.
• Passive RFIDs: Passive RFIDs are cheaper compared to active RFIDs. They do not have any external source of power and hence most of the times they are passive. These tags are activated whenever it comes within the electromagnetic range of a RFID reader. The frequency generated from the reader activates the passive device and it reflects back the information stored in the tag. However these tags have a comparatively lesser read range and are not writeable. The lack of need of an external power source makes these tags virtually of unlimited life.
Each type has its own set of uses: active RFIDs are mostly used in expensive items where there is a need to store a lot of information. For low cost-high volume items passive tags make more sense.
Tags can be either read only or WORM (Write Once Read Many) or complete read/write enabled depending on the usage requirements.
RFIDs are also classified based on the frequency band they operate in for example HF, UHF, LHF etc. Low frequency lags have lower read ranges and lower system costs. Generally the range and cost goes up with the increase in frequency. LF tags are in the range of 30 KHz to 500 KHz. The frequency also determines the range and usability, for example UHF tags are not suitable for pharmaceutical products etc.
RFID CLASSIFICATION BASED ON FREQUENCIES
1. Low Frequency (LF): These tags typically have a frequency of 125 KHz and 134 KHz. These tags have the benefit of minimu

FASHIONING AGILE SUPPLY CHAINS
Supply Chain Imperatives for Fashion & Luxury Branding in India
At $511b in 2008 the maturing Indian retail market 1 holds promise for retailers globally, especially in light of the current economic turbulence: despite setbacks in the United States and Europe, GDP growth in emerging markets like India is still expected to top 7%.
In addition, households with real earnings of more than 1,000,000 INR a year (classified as global by McKinsey 2 ) will comprise 2% of the population by 2025, but earn almost a quarter of its income. Burgeoning disposable incomes & heightened awareness have created a discerning, global consumer who demands from Indian retail, and gets, the same experience as anywhere else in the world. Targeting this audience is opportunity, and challenge, for India’s luxury & lifestyle retailing industry.
In order to understand the supply chain imperatives governing fashion and luxury retailing in India, it is necessary to understand the various trends that are the zeitgeist today.
KEY TRENDS AFFECTING RETAIL SUPPLY CHAIN
Faster Fashion Traditional four seasons have given way to offering fresh merchandise every two to three weeks, giving the shopper a fresh, new look regularly. Zara offers an average 11,000 articles in a given season compared to 3,000-4,000 for peers, resulting in average annual customer visits of 17 compared to 3- 4 for competing chains 3 . Underpinning this ability is Zara’s “design-to-shelf” supply chain capability of 3 weeks.
Offering new merchandise every two or three weeks, Chico’s business model focuses on producing less quantity of an individual product, but more types of merchandise to satisfy its customer. Customers know that if they like an item, they need to purchase it when they see it otherwise it might not be there on the next visit.
