But there are security solutions to this. As a rule, it is very difficult to retrieve data unless the RFID tags happen to be sending or receiving data at the time. To capture data, a scanner has to be within range of the RFID chip. The low range of passive chips makes data theft especially difficult. You can carry your cash card and car key in a shielded pouch if you want to protect it. A piece of tin foil is usually enough to prevent any unwanted communication. A digital twin enables you to depict existing and planned equipment and Where do you want to work today?
Let employees decide with a collaboration People who work in flow are more productive: keep the flow going in your Table of Contents. How does RFID work? What uses are there? Are there risks too? Share this article:. Rate this article:. For those reasons, many companies are looking to RFID to add even more value to their operations. With RFID, supply chain businesses can track the movement of their inventory items and assets.
By eliminating labor-intensive inventory tracking processes that require human intervention and increasing visibility of your items and assets, RFID can help businesses cut costs related to manufacturing, distribution, inventory management, and asset tracking. An automated data collection system — especially one that does not require human intervention — improves speed and accuracy so that employees can get more done in a shorter amount of time and get it done right the first time.
Because of this, RFID allows businesses to decrease their labor costs. And with improved accuracy, businesses can also increase their throughput, and therefore reduce their inventory carrying costs as well. Not to mention, improved accuracy can yield even more benefits. When shipments arrive on time and in the right quantities, customers are bound to be more satisfied with your service.

In November , President George Bush signed a bill for the standardization of pet microchips and a national database of pet owner information [source: RFID Journal ].
Even though the FDA approved the implantation of RFID microchips in animals and humans in , research from as far back as shows that these implants can cause cancerous tumors in lab rats and mice [source: Washington Post ]. Specifically, the implants caused sarcomas, which affect body tissue. No studies have proven yet that cancer can form in animals other than lab rats and mice, and it's still too early to tell what effects the chips can have on humans. No negative health effects have been linked to the radio waves emanating from RFID chips.
Despite this evidence, or lack thereof, other disadvantages of human chipping may outweigh its advantages. VeriChip Corp. The company makes microchips with unique identification numbers that link to a VeriChip medical database. The VeriChip database contains emergency contact information and medical histories.
Patients with serious medical issues like Alzheimer's are ideal candidates for the VeriChip. In addition to a one-time implantation fee, VeriChip charges annual fees based on how much information you want in the database -- you can choose to have just your name and contact information or your full medical history. Also, doctors might not scan every patient to check for a chip, so depending on the hospital or doctor, your VeriChip could prove useless.
If an unauthorized person tries to remove a baby from the hospital, an alarm is sounded at the nurses' station and at exit doors. You can read more about successful infant abduction prevention on the VeriChip Web site. In the next section, we'll hear what RFID critics have to say about tracking devices in our modern world. Under this system, sensors attached to a crib sound an alert if they detect that the baby has stopped breathing, potentially saving young lives.
As with many new technologies, people fear what they don't understand. In the case of RFID, consumers have many fears, some of which may be justified.
This debate may be one of the few in which you'll find the American Civil Liberties Union and Christian Coalition on the same side. Human chipping has seemingly higher stakes than merchandise tagging, and RFID critics are concerned that human chipping may one day become mandatory.
When the company CityWatcher. Other employees declined the implants, and their positions with the company were unaffected. Some believe that human chipping is foretelling a biblical prophecy from the Book of Revelation, interpreting the chip as the "Mark of the Beast.
While we can choose whether or not to put RFID chips in ourselves or our pets, we have little control over tags being placed on commercial products that we buy. They describe how RFID tags could be used to gauge your spending habits and bank account to determine how much you should be charged for the products you buy.
This may sound paranoid, but hackers have proven that some RFID tags can be tampered with, including disabling their anti-theft features and changing the price that corresponds to their product. Better encryption is needed to ensure that hackers can't pick up RFID frequencies with super-sensitive antennae. What's more, some critics say that relying on RFID as the primary means of security could make human security checkpoints lazy and ineffective.
If security guards rely solely on the RFID anti-theft devices in merchandise and RFID technology of government-issued identification to screen for criminals or terrorists, they might miss the criminal activity happening right in front of their eyes. In October , California governor Arnold Schwarzenegger signed a bill making it unlawful for any employer to force an employee to be chipped.

High-Tech Gadgets. Reinventing the Bar Code " ". Bar codes like this one are found on almost every product we purchase.
In order to keep up with inventories, companies must scan each bar code on every box of a particular product. Going through the checkout line involves the same process of scanning each bar code on each item. Bar code is a read-only technology, meaning that it cannot send out any information. RFID tags like these used to be made only for tracking luggage and large parcels.
The tag's antenna receives electromagnetic energy from an RFID reader's antenna. Using power from its internal battery or power harvested from the reader's electromagnetic field, the tag sends radio waves back to the reader. The reader picks up the tag's radio waves and interprets the frequencies as meaningful data. Talking Tags When the RFID industry is able to lower the price of tags, it will lead to a ubiquitous network of smart packages that track every phase of the supply chain.
At the grocery store, you buy a carton of milk. RFID tags come in different shapes, sizes and materials. Understanding different RFID tag types will enable you to choose the right option for your unique environment. Below are the key tag types commonly used as part of an automatic vehicle identification system.
Windscreen Tags usually come in the form of a sticker that you can apply to the vehicle's windscreen from the inside. It is a passive tag and as such does not contain a battery.
Windscreen tags are a cost-effective solution for applications such as parking - perfect for upgrading existing proximity parking access control systems. It's completely maintenance-free and is very easy to install. Once applied, the thin, flexible sticker format is permanently attached to the windscreen, offering a tamper-resistant automatic vehicle identification solution.
For added security, companies can also request tamper-resistant windscreen tags that will show visual proof of removal and are difficult to remove intact and functional. In situations where vehicle windscreens are fully metallised, a passive exterior tag will do the trick.
