| "The baiMobile® Privacy Activation feature, contains a user-activated, circuit connection button, which is embedded in standard high frequency and ultra-high frequency cards. It completely disables RF functionality of the card's loop antenna circuit until the privacy activation button on the card is squeezed." |

 Ultra High Frequency (UHF) Identification Cards
The future lies in cards that work at convenient distances of up to 9 meters. Ultra High Frequency (UHF) RF identification cards use reflective technology to achieve increased read range (like toll booth tags), making them the card of choice for vehicle access at national borders and other points of entry because they can be presented at a distance and in any weather. Identity verification time is reduced and processing throughput is greatly increased.
Security Vulnerabilities are Inherent in RFID
A fundamental weakness of all contactless cards is that they can be surreptitiously read, cloned, and tracked by persons using only public information and readily available electronic surveillance equipment. These inherent vulnerabilities extend to proximity cards, vicinity cards, and UHF longer distance cards.
The ISO/IEC 14443 standard calls for a 10 cm read distance from the reader to the card. This range is achieved assuming that a regulation 1/2 watt transceiver is used to excite the card. By raising the transmitted power, it is possible to extend the read distance to 6 feet – far enough that an antenna can "skim" the RFID chip through plasterboard and even into the wallets of unsuspecting passersby. If that wallet contains an electronic passport, then the unique data stored on the chip (name, address, nationality, passport number, etc) can now be easily accessed by identity thieves, kidnappers and even terrorists.
The early defense against misuse of proximity cards was to transmit a code to the card and have the card return an encrypted response. Unfortunately, this can be defeated by using a "relay attack". Use of protective sleeves is one solution, but experience has shown that cardholders forget, misplace or simply do not use the sleeves when the card is not in use. |
 The baiMobile™ Secure Contactless Card with Personal Privacy Activation
Because ordinary RF card data can be surreptitiously interrogated, it is important to make sure that the card is totally disabled and electronically silent until the cardholder needs to activate the card. The baiMobile™ Privacy Activation feature, contains a user-activated, circuit connection button, which is embedded in standard high frequency and ultra-high frequency cards. It completely disables RF functionality of the card's loop antenna circuit until the privacy activation button on the card is squeezed. |
