Cubic has been granted a patent for a gate that regulates access in a transit system. The gate includes a movable barrier, secured storage, an RFID card reader, and processing units. It uses RFID credentials and hash values to determine access validity and control the opening of the barrier. The gate also has a memory with a higher capacity than the secured storage to store information about valid access credentials.

A gate for regulating access in a transit system
A recently granted patent (Publication Number: US11763617B2) describes a gate for regulating access in a transit system. The gate includes a movable barrier, a secured storage on a first circuit card, and a Radio Frequency Identification (RFID) card reader coupled with the secured storage. A first processing unit is configured to read a set of digits from an RFID credential, generate a hash value of the set of digits, transmit a first bank identification number (BIN), and transmit the hash value. The gate also includes a memory on a second circuit card with a larger capacity than the secured storage. A second processing unit coupled with the memory receives the first BIN and sends validity information for a plurality of second BINs to the first circuit card. The second processing unit also checks the hash value in a list of hash values associated with RFID credentials in the memory. The first processing unit regulates the opening of the movable barrier based on the hash value and denies opening if the second BIN corresponding to the RFID credential is invalid.
The patent also describes additional features of the gate, such as the RFID card reader processing the RFID credentials at a normal pace of 2 meters per second and within a half-second interval. The RFID credentials can be provided through an RFID card or stored on a smart device. The gate can also regulate the opening of the movable barrier based on whether the hash value is on a first list, opening the barrier if it is not on the list and denying opening if it is on the list. The first BIN consists of six digits of the RFID credentials, while the plurality of second BINs consists of 7-11 digits. The first list includes RFID credentials that are blacklisted by the service provider issuing the credentials.
In addition to the gate, the patent also describes a method for regulating access in a transit system and a non-transitory computer-readable medium with embedded instructions for implementing the method. The method and computer-readable medium include similar steps and features as the gate, such as reading the set of digits, generating a hash value, transmitting the BIN and hash value, checking the hash value in a list of hash values, and regulating the opening of the movable barrier based on the hash value and validity of the second BIN.
Overall, this patent presents a gate and associated methods for regulating access in a transit system using RFID credentials and hash values. The gate includes various components and processing units to ensure secure and efficient access control.
