A dangle, which plugs into the audio / earpiece jack of host devices, allows them to accept payment cards as a point of sale (POS) terminal. It contains a magnetic stripe (magstripe) card reader, a smart card reader, and / or a proximity card reader (reader(s)); a microprocessor or microcontroller (CPU); and a circuit for drawing power from a digital audio signal (power circuit). Payment card data is collected by the reader(s), passed to the CPU where it is encrypted, encoded, and modulated, sent to the host device through the Microphone input contact of the audio / earpiece jack, then transmitted via one the host device's networks to a merchant account provider for processing. A digital audio signal, constantly generated by the host device, provides power to the dongle via the power circuit. The power circuit converts the digital audio signal to stable DC power with the appropriate voltage for powering the dongle's other components.

A fast data transfer collection system using message authentication and contactless RF proximity card technology in non-contact storage and retrieval applications. The system is generally comprised of Host computers (application computer systems), Target radio frequency (RF) terminals, and a plurality of portable Tags ("smart" or "proximity" cards). A Host provides specific application functionality to a Tag holder, with a high degree of protection from fraudulent use. A Target provides control of the RF antenna and resolves collisions between multiple Tags in the RF field. A Tag provides reliable, high speed, and well authenticated secure exchanges of data / information with the Host resulting from the use of a custom ASIC design incorporating unique analog and digital circuits, nonvolatile memory, and state logic. Each Tag engages in a transaction with the Target in which a sequence of message exchanges allow data to be read(written) from(to) the Tag. These exchanges establish the RF communication link, resolve communication collisions with other Tags, authenticate both parties in the transaction, rapidly and robustly relay information through the link, and ensure the integrity and incorruptibility of the transaction. The system architecture provides capabilities to ensure the integrity of the data transferred thus eliminating the major problem of corrupting data on the card and in the system. The architecture and protocol are designed to allow simple and efficient integration of the transaction product system into data / information processing installations.

A fare payment system including a proximity card; an antenna to read and write information onto the card, preferably a Mifare antenna; a processor connected to the antenna; a validator or POS processor, where the processor is entirely independent from the validator or POS processor; and one or more SAM storage modules which contain tables, access codes and other sensitive information. The SAM module is also controlled by the system administrator, which allows dynamic and diversified codes to guarantee the security and veracity of the information being transmitted. The system, method and apparatus of the present invention are capable of being programmed regardless of the POS processor, and any sensitive data can be withheld entirely from the suppliers of the antenna and POS processor technology. Additionally, because each antenna has its own processor, it can work both on-line and off-line. The processor also has a non-volatile EEPROM memory for information storage, but stores the access codes and other sensitive data in volatile memory so that a power loss will erase the access codes from the processor memory, leaving them only in the storage module memory. All of these features restrict access to sensitive system information and secure that information from outside suppliers.

The present invention relates to access control systems using proximity cards, and in particular, to a proximity card and an associated method for controlling activation of the proximity card. The proximity card includes an actuation sensor and an access electronics system connected to the actuation sensor, the access electronics system configured to activate the proximity card in response to an input from the actuation sensor to enable communication of the access information from the proximity card.

The system and method for detecting duress using a proximity card comprising at least one transponder and a switch. The switch configured to activate with the user's touch. The switch comprising a thermistor, a piezoelectric sensor, an exposed electrode, a capacitive sensor, or the like, which is located on the proximity card. The switch is configured to modify the signal form a first transponder, or activate a second transponder, thereby sending a duress signal. If a duress pattern is recognized, then the system notifies another party of the situation, or sets a system flag.

An access control device with an efficient distance setting includes a main system and an active proximity card, and the main system includes a first microprocessor coupled to a first signal receiver, and the first signal receiver has a first receiving sensitivity, and the first microprocessor has a first signal reception intensity setting, and the active proximity card includes a signal transmitter. After the first signal receiver receives a control signal transmitted from the active proximity card, the first signal receiver will transmit the control signal to the first microprocessor. If the intensity of the control signal is greater than or equal to the intensity of the received first signal, the microprocessor will execute the control signal to prevent the main system from processing too many unnecessary control signals or prevent the control signal transmitted from the active proximity card from being executed by many main systems.

The invention discloses an expressway deck runoff treatment and accident emergency system, which comprises the following parts: a treatment unit, a remote proximity card arranged on a hazardous chemical transportation vehicle, card readers arranged at front and back ends of a bridge, a control system and each electromagnetic valve controlled by the control system. The system disclosed by the invention is used for carrying out oil, water and solid separation on rainwater runoff on the deck, the occupied space is small, the efficiency is high, the system can be arranged nearby at two sides of the bridge, sewage can be treated in time, the quality of directly discharged water can meet requirements of environmental protection, and the system is particularly suitable for expressway bridges. The system can also meet the requirements of environmental protection in extreme severe weather such as rainstorm. A conducting valve is controlled to be opened and closed in three different work states: the normal state, the preparation state and the emergency state, so pre-warning and preparation for dealing with accidents can be realized; even under the condition of no monitoring by personnel, any chemical does not leak after a leakage accident of hazardous articles occurs, and risks of polluting water sources such as rivers and lakes are eradicated.
