Air travelers are all familiar with the congestion problems at the curb of airport arrival/departure areas. The drop off / pick up areas are shared by passenger cars, taxis, busses, and courtesy vans. Some airports have implemented control of taxis, busses, and courtesy vans by tagging them and then checking the amount of time or number of trips each vehicle makes. By charging a fee for any excess trips or wait time, airports have been able to free up curb space and reduce congestion.

While studying the congestion problem, some airports noticed that there were lots of local toll tags on vehicles that came to the airport. In many cases, the tagged vehicle stayed in the parking facility for the duration of the traveler’s trip. This discovery led to the airport parking authority reading the UHF RFID toll tags to reduce staffing at the exit booths and improved service to the travelers.

On Metal tags are designed specifically for attaching to metallic surfaces and will more often than not perform badly if attached to a non-metallic item.

They are available in a wide range of formats and can be stuck onto a surface, screwed, riveted etc. the fixing choice being dependent on a variety of factors.

As with all other RFID tags they are available with a vast array of memory options, orientation options and can of course be available with unique unalterable serial numbers or blank so that an ID can be set by the user.

Frequently On Metal tags are used in harsh environments such as drying booths in paint spraying shops or attached to beer kegs or gas bottles that are exposed continually to the elements.

They also find use in process control in various industries where they are attached to pipework or valves to assist in the correct identification of a particular piece of equipment. The tags are encapsulated in various materials and dependent upon the type of encapsulation and quantity can be personalised with various information etched or printed onto them.

Ultra high frequency

Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz, also known as the decimetre band as the wavelengths range from one meter to one decimeter. Radio waves with frequencies above the UHF band fall into the SHF (super-high frequency) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications.

The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz.[1] Two other IEEE radar bands overlap the ITU UHF band: the L band between 1 and 2 GHz and the S band between 2 and 4 GHz.

Which Applications Need High Memory RFID Tags?

The best way to answer this question may not be necessarily to call out specific applications that may (or may not) need high memory – for example, asset tracking, etc. Rather, a better way to determine if an application needs high memory RFID tags, is to determine if the application will be able to have reliable access to a database (as needed) in order to pull up relevant information about the tagged object.

Because a database can theoretically store as much information as required about any given tagged object, as long as the user has access to that database, the only thing a tag really needs is a unique ID within that application. In such a case, the user would simply read the RFID tag and then be able to pull up as much information as needed (assuming the user interface is designed accordingly). The database access could occur in real-time if the RFID reader is connected to a network, but can also occur if, for example, a user has a mobile RFID handheld reader that has a local copy of the database. (In this example, the local database would need to periodically sync with the master database.)

In the event that reliable database access isn’t possible and the user must store data about the tagged item, then storing data on the tag itself may be the best option and this is when high memory RFID tags would be needed.

Alien Higgs-3 chip conforms to the EPC global Class 1 Gen 2 specifications and provides state-of-the-art performance for a broad range of applications.

The read range depends on the environment and the respective country regulations. The allowed frequency band has to be selected. TAG and RFID reader need to be coordinated to each other.

WHY UHF RFID FOR THE WAREHOUSE?

Unlike scanning barcodes, UHF RFID technology allows warehouses and distribution companies to track their inventory without human intervention. This makes the technology ideal for harsh environment applications where reading barcodes may be difficult.

For warehouses with high volume and large amounts of inventory on hand, UHF RFID tags eliminate the need for direct line of sight or labor-intensive tag reading because they do not have to be scanned.

By eliminating human intervention,UHF RFID can help warehouses reduce labor hours and costs related to inventory control and asset management in manufacturing or distribution environments. By streamlining these processes, warehouse managers can improve customer service and increase the speed and accuracy of their shipping operations.

RFID Application in Industrial Environments

Even though RFID gets a lot of attention, many companies are unclear about the benefits they will enjoy by using RFID. Here are a few key ways to use RFID tags and scanners to improve productivity, efficiency, and accuracy in industrial environments such as warehousing, manufacturing or distribution.

Check-In / Check-Out Tooling and Jigs
Most industrial environments strive to reduce or eliminate downtime, so it can be disruptive and frustrating when necessary tooling, fixtures, jigs and required supplies aren’t readily available when it’s time for a setup. Using RFID tags on tooling helps ensure you always know where it is. Scanners at the entrance of the tool crib automatically track when tooling leaves the area, and barcode scanners can locate the missing item if it was not returned after its last use.

Rapid location of missing items helps reduce or eliminate delays in setup, decreasing unnecessary downtime and increasing production throughput.

Inventory Accuracy
Using RFID tags on inventory streamlines every aspect of inventory management. For example, you may be able to perform a complete physical inventory by having every item in the warehouse signal its presence. This eliminates a costly and tedious process.

Using RFID tags also helps reduce theft and pilferage, because scanners automatically record the movement of tagged items whenever they pass out of a secure location. This added layer of security helps reduce inventory shrinkage and increases margins. In addition, since inventory and other data records will be more accurate, you may be able to reduce or eliminate safety stocks.

Tracking Rental Goods
If you rent out items, RFID tags can perform the time consuming and tedious check-in and check-out process. Making this process fast and painless for customers increases their satisfaction with your service, and accurate records that can’t be faked or misread helps eliminate disputes about the length of a rental period.

Mixed Pallets and Serialization
Tracking serialized goods can be challenging to track, even with barcodes, because it typically requires each item to be scanned individually. RFID scanners can capture an entire pallet of serial numbers as the pallet passes the scan point, so the pallet moves faster. This reduction in move time speeds up on-time delivery by reducing the order cycle time. It also increases inventory accuracy by eliminating incorrect serial number entries and enables tighter controls with less effort.

The same principle holds true for items with expiration dates or if you manage your inventory using either LIFO or FIFO picking. The RFID tag automatically lets the system know which item best meets the picking criteria and directs the worker to select that item.

If your product mix varies so that you ship mixed pallets, RFID tags will speed up transaction processing, because the scanner can read the RFID tag for every item on the pallet in a single pass, even if they are lot or serial controlled. This is much faster than entering each item’s data individually.
