A special kind of radio technology known as radio frequency identification, or RFID, uses radio waves to recognize tags attached to an object and identify it.
The transceiver chip in the tag gets activated by the electromagnetic wave from the RFID reader and transmits an identification number back to the reader. Once the inventory of the items with tags is complete, the identification number gets used. You can use passive or active tags. The operational range of passive tags is limited because they get solely powered by the incident electromagnetic wave from the scanner. The active tags can extend to hundreds of meters and are battery-powered.
RFID tags do not require a direct line of sight when using wireless technology. In contrast to the barcode scanners currently often utilized in the industry, RFID tags that use wireless technology do not require a direct line of sight to the RFID reader.
Below are 5 popular products used RFID technology.
RFID Wallet
A part constructed of metal that works to prevent unauthorized scanning or skimming gets typically seen in wallets equipped with RFID-blocking technology. When looking for an RFID-blocking wallet, look for 13.56 MHz, even though RFID-blocking technology may operate at other frequencies. The RFID Wallet gets used by passive ID badges, credit cards, and debit cards.
RFID Passport Cover
A passport wallet protects your travel papers and prevents you from arriving at the airport with a damaged passport that can no longer get used. It might be complex to stay organized while traveling, and many passport wallets also come with pockets and zippers. The best passport wallet available if you utilize RFID-blocking technology. The RFID Passport Cover has many pockets, is incredibly thin, extra roomy, and with anti-theft technology.
RFID Tickets
Transportation networks, event venues, festivals, and sports stadiums can all benefit from RFID tickets for access control and verification. Customers benefit from their speed and ease, while suppliers have access to vital customer information thanks to them. With minimal expense and the ability to expand events in the following years, this technology made it possible to offer a fully functional payment solution to hundreds of vendors and several guests. RFID tickets can get purchased as plastic cards, ABS wristbands, key chains, tokens, and other items.
RFID gun
Only the designated user can fire the weapon in a user-unique RFID gun. The gun’s handle contains a radio chip that regulates access, and the authorized user wears a watch, ring, or bracelet or even has the chip implanted in their hand. The trigger won’t unlock if the two chips are not close together (within a few millimeters). The safety mechanism can get released using the radio-controlled watch activated by a PIN code.
When the pistol loses radio communication with the watch, such as when it gets knocked out of the shooter’s hand, misplaced, or stolen, it deactivates.
RFID key cards
A more recent innovation in the hotel industry is RFID key cards. Simply pressing the key card to a pad on the hotel room door allows customers to enter their rooms. They are highly adaptable as you regularly update and upgrade your hotel security because of their interoperability with different locking systems. The key cards with RFID technology typically have a longer lifespan and require less upkeep than magnetic cards.
