What is High Frequency (HF) RFID?
Most RFID systems operating in a high-frequency (HF) range will come in at 13.56 MHz, through they can range anywhere from 3 to 30 MHz.
Is Near-Field Communication (NFC) the same as HF RFID?
NFC, or near-field communication, is a subset of HF, and it works in the standard 13.56 MHz range. The NFC protocol was approved by the International Organization of Standardization, or ISO, and operates in the proximity of only a few centimeters (depending on conditions) and without line-of-sight readers (no physical contact is required).
How is HF RFID used?
HF RFID systems have a somewhat greater read range than low-frequency RFID transmissions - up to about a meter - and have larger memory options. These systems are becoming increasingly more popular in marketing and interactive experiences, as well as critical access control and data transfer applications.
This type of tag is often used for inventory tracking, as it is small and can be read quickly. HF RFID tags are also less expensive than LF but typically more expensive than UHF. They are also for transit tickets because they are durable, waterproof and easy to wear on clothing so they won't get lost. They also have high memory capacity, which allows them to store more information than other types of RFID tags.
HF RFID for Marketing and Interactive Experiences
High frequency (HF) RFID is all around us. It's in our phones, our wallets, and even in the chip used to pay for items at gas stations or grocery stores. HF RFID is used in marketing and interactive experiences to improve the customer experience. Retailers use HF RFID for the following:
- Improving accuracy and efficiency of stock tracking; customers no longer have to wait for a store employee to help them find an item on a shelf.
- Creating interactive displays that change based on what items a customer picks up.
- Allowing customers to pay for items without having to swipe a card or type in a PIN.
- Providing information about products including where they were made, how they were made and what ingredients were used.
HF RFID in Libraries
Libraries could use HF RFID tags to keep track of books, including making it easier to find books and tracking which books are being checked out and borrowed. Additionally, HF RFID tags are used to track and monitor medical supplies and inventory. This helps ensure that hospitals have the supplies they need in stock.
HF RFID in Quality Control
HF RFID is used in large warehouses and distribution centers to quickly track pallets and large cases. This is especially useful in distribution centers where there are many items being moved around at once. Using RFID technology, these centers can track everything and ensure that nothing is misplaced.
HF RFID technology can also be used for quality control. For example, some companies use RFID sensor tags that monitor temperature and other environmental factors for wine or other high-value items. This helps to ensure that the products are being stored and transported in the correct conditions to avoid damage.
