If you’re unaware of why RFID technology is getting popular gradually, then let me tell you. Well, RFID is an abbreviation of radio frequency identification where several technologies are summed up that use radio frequencies for the identification of objects. Who wouldn’t want to add speed, accuracy, efficiency, and, security to an ever-expanding range of applications? The UHF RFID tag manufacturer offers the most diverse and flexible line of tracking tags, backed up with RFID development and manufacturing expertise.
Well, the RFID tag is a small object, with a chip and antenna for wireless identification of the objects that are attached to an RFID reader. Most of them are passive, which means they don’t need any maintenance and they operate without battery power for years to come.
Types of RFID tags:
They are powered by an RFID reader that emits an electromagnetic field. The antenna of the RFID tag harvests energy from this field for releasing a signal to the reader. You must consider the frequency of the reader should match the frequency of the tag. The standardized frequencies for passive tags include low, high, and, ultra-high (L, HF, UHF ).
The low-frequency readers can only read one tag at a time like an ID of sheep or a piece of clothing. On the other hand, high-frequency or ultra-high-frequency readers can read multiple tags concurrently like a pallet of goods or a stack of tagged books.
They use a battery to broadcast through Bluetooth Low Energy (BLE) and Wi-Fi.
The RFID tags come in various form factors depending on usage, fixation, and, the requirement for robustness. Typical form factors are:
– Sticky label or dry inlay
– Glass capsule
– Rectangular block (either with screw holes or steel ring)
– ISO card
– Special form factors like built-in cable, tamper protection, keyfob, etc.
Applications of RFID tags
RFID tags are most commonly used whenever there’s a need to identify any physical object quickly and reliably.
Following are the areas where the utmost importance is given to RFID tags
– Medical and health equipment
– Commercial laundry
– Returnable transport items
– Automation and manufacturing
– Retail logistics
– Electronic passports and ID cards
– Contactless access control systems
– Contactless payments
– Animal identification (pets, lab animals, etc.)
Benefits associated with RFID tags
They are typically used to identify the items to which the tags are attached or embedded.
– Everything is located and identified automatically with no involvement of manual labor. Hence, no human error.
– Improved accuracy and inventory speed.
– The optimized workflow of logistics and handling of items.
Without the RFID system, it would’ve been exceedingly difficult to have an automated track on physical objects The cost of these tags vary depending on the tag’s capability, memory size, and, durability. It’s not only made for identification purposes but it could also be used for transferring the information from one device to another.
