Devices using contactless smart card technology use RFID technology, but, by design, operate at a short range (less than 4 inches) and can support the equivalent security capabilities of a contact smart card chip (see below). Contactless smart cards, devices and readers conform to international standards, ISO/IEC 14443 and ISO/IEC 7816, and can implement a variety […]
A contactless smart card includes an embedded smart card secure micro-controller or equivalent intelligence, internal memory and a small antenna and communicates with a reader through a contactless radio frequency (RF) interface. Contactless smart card technology is used in applications that need to protect personal information and/or deliver fast, secure transactions, such as transit fare […]
Buying a wallet used to be a relatively simple decision. You had your choice of a bifold, trifold, credit card sleeve or maybe just a money clip. Now if you flip through tech or gadget magazine, you’ll find a whole new genre of wallets that are designed with RFID blocking protection. Like this one from Common Fibers and […]
How To Block RFID From Reading Your Credit Card? Step 1 Wrap your credit card in aluminum foil. The aluminum foil shields the credit card from RFID signals. You can also place the credit card in a container made from a conducting metal. Step 2 Purchase an RFID-blocking wallet. Many companies sell shielded wallets, which […]
Radio frequency identification (RFID) is a technology enabling a contactless exchange of data. This technology features the possibility to wirelessly transfer power to the transponder (opponent). High Frequency RFID is used in mobile devices like smart phones and shows potential for applications like payment, identification, etc. Unfortunately, the needed functionality increases the battery drain of […]
UHF RFID Card have a good read range and a high data transfer UHF frequency band covers the range from 300 MHz to 3 GHz. This method of identification offers several advantages over traditional methods involving ID cards (tokens) or PIN numbers (passwords) for various reasons: (1) the person to be identified is required to […]
The extended read range capabilities of UHF technology enables faster and more accurate tracking, and it is widely used for secure access control , waste management, shipping and receiving, fleet management, and pallet and goods tracking systems. The powerful reading capabilities of UHF eliminate the need for cardholders to stop at the door of a […]
Passive RFID card provides advanced sensitivity for enhanced read rates and range. The read range of passive UHF systems can be as long as 12 m, and UHF RFID has a faster data transfer rate than LF or HF. UHF RFID is the most sensitive to interference, but many UHF product manufacturers have found ways […]
RFID companies have been quick to respond to the challenge of keeping libraries open in these austere times. The Vatican Library in Rome is the latest, and one of the most high profile, of scores of libraries worldwide that are adopting RFID technology in libraries of books and other items. The main benefit is that […]
RFID products appear our life everywhere, and this RFID products includ RFID hotel key card, RFID wristbands, ABS keytag and so on. Nowadays, there are more and more hotels starting to use RFID hotel key card to make sure the security of access control, along with the gradual lowering of RFID (radio frequency identification) cost. […]
