Over 2,600 commercial vehicles found entering Delhi through 13 major entry points without RFID tags or having insufficient recharge amount were penalised. From September 13 midnight only those commercial vehicles which have RFID tags are allowed to enter Delhi.

"From the midnight of September 13, around 2,625 commercial vehicles have been found entering Delhi through the 13 entry points without radio-frequency identification (RFID) tags or insufficient recharge amount in their tags.

"Vehicle owners or drivers of all these vehicles were penalised twice the amount of toll and Environment Compensation Charge (ECC) was recovered before allowing them to enter Delhi," the SDMC said in a statement.

The SDMC also said that it has been noticed that despite sale of more than three lakh RFID tags, commercial vehicle owners or drivers are "reluctant to recharge their tags".

South Delhi Municipal Corporation (SDMC) has started cashless collection of 'Environment Compensation Charge' (ECC) and toll at all of its 13 toll entry points in the national Capital through newly-installed state-of-the-art radio frequency identity (RFID) system.

What is RFID?

RFID is an acronym for “radio-frequency identification” and refers to a technology whereby digital data encoded in RFID tags or smart labels (defined below) are captured by a reader via radio waves. RFID is similar to barcoding in that data from a tag or label are captured by a device that stores the data in a database. RFID, however, has several advantages over systems that use barcode asset tracking software. The most notable is that RFID tag data can be read outside the line-of-sight, whereas barcodes must be aligned with an optical scanner. If you are considering implementing an RFID solution, take the next step and contact the RFID experts at AB&R® (American Barcode and RFID).

HOW DOES RFID WORK?

RFID belongs to a group of technologies referred to as Automatic Identification and Data Capture (AIDC). AIDC methods automatically identify objects, collect data about them, and enter those data directly into computer systems with little or no human intervention. RFID methods utilize radio waves to accomplish this. At a simple level, RFID systems consist of three components: an RFID tag or smart label, an RFID reader, and an antenna. RFID tags contain an integrated circuit and an antenna, which are used to transmit data to the RFID reader (also called an interrogator). The reader then converts the radio waves to a more usable form of data. Information collected from the tags is then transferred through a communications interface to a host computer system, where the data can be stored in a database and analyzed at a later time.

RFID TAGS AND SMART LABELS

As stated above, an RFID tag consists of an integrated circuit and an antenna. The tag is also composed of a protective material that holds the pieces together and shields them from various environmental conditions. The protective material depends on the application. For example, employee ID badges containing RFID tags are typically made from durable plastic, and the tag is embedded between the layers of plastic. RFID tags come in a variety of shapes and sizes and are either passive or active. Passive tags are the most widely used, as they are smaller and less expensive to implement. Passive tags must be “powered up” by the RFID reader before they can transmit data. Unlike passive tags, active RFID tags have an onboard power supply (e.g., a battery), thereby enabling them to transmit data at all times.

Although RFID technology has been in use since World War II, the demand for RFID equipment is increasing rapidly, in part due to mandates issued by the U.S. Department of Defense (DoD) and Wal-Mart requiring their suppliers to enable products to be traceable by RFID.

Whether or not RFID compliance is required, applications that currently use barcode technology are good candidates for upgrading to a system that uses RFID or some combination of the two. RFID offers many advantages over the barcode, particularly the fact that an RFID tag can hold much more data about an item than a barcode can. In addition, RFID tags are not susceptible to the damages that may be incurred by barcode labels, like ripping and smearing.
From the read distance to the types of tags available, RFID has come a long way since World War II and there is a bright future ahead. Review the evolution of RFID.
