A method including receiving, in a security device, a user object storing stored biometric data describing a biometric parameter of the user. Sensed biometric data is generating by sensing directly, using a sensor, the biometric parameter of the user. The stored biometric data is compared to the sensed biometric data. A confidence factor is determined using a first degree of trust, assigned to the object, combined with a second degree of match between the stored biometric data and the sensed biometric data. A user input is received indicating a desired activity. A risk factor is determined based on a combination of the confidence factor and the user input. The risk factor is compared to a selected pre-determined threshold. The user is granted a selected level of access to the security device from among different levels of access to the security device when the risk factor satisfies the selected pre-determined threshold.

Disclosed is an electronic device, including: a switch element; and a memory card slot suitable for receiving a memory card. The memory card slot includes a power supply pin and a detection pin, and the power supply pin of the memory card slot being connected to a power supply through the switch element.

One or more paddles may be included, each having at least one electrode connected to the electrical output, wherein each paddle is configured to enter an opening of a battery-powered device for receiving a smartcard, wherein the at least one electrode is configured to provide electrical power from the power input to the at least one electrical contact to provide electrical power the battery-powered device.

Systems and methods provided herein may include a card replacement system. The system may include an automated teller machine in data communication with a server. The automated teller machine may include an input device; a processor; a replacement card storage containing at least one replacement card, wherein the at least one replacement cards may include a magnetic stripe and a chip; a magnetic stripe writer; a chip writer; and an embossing device. The processor may be configured to: receive a replacement card request via the input device; request replacement card information from the server; encode replacement card information onto the replacement card using the magnetic stripe writer and the chip writer; and emboss user information onto the replacement card using the embossing device.

An electronic device includes a card interface and a processing module. The card interface is electrically connected to the processing module, and a SIM card or a memory card may be inserted into the card interface. The card interface includes 8 springs, where N>1; when a memory card is inserted into the card interface, the memory card is electrically connected to the processing module; and when a SIM card is inserted into the card interface, the SIM card is electrically connected to the processing module, and one metal pin of the SIM card is electrically connected to a first spring in the N springs and one spring adjacent to the first spring. The processing module is configured to determine, based on at least a level of the first spring, that an inserted card is a SIM card or a memory card.

A memory card access module and a memory card access method are provided. The memory card access method is applied to an electronic device. A processing unit of the electronic device accesses a memory card through a memory card slot. The method includes steps of: detecting whether the memory card supports a Peripheral Component Interconnect Express (PCIe) interface; when the memory card does not support the PCIe interface, controlling the processing unit to access the memory card through a data transmission path and performing data format conversion between a transmission interface and the PCIe interface using a memory card access unit disposed on the data transmission path; and when the memory card supports the PCIe interface, controlling the processing unit to access the memory card through a PCIe data transmission path that allows the processing unit and the memory card to transmit data through the PCIe interface.

In a card connector, a main body has a plugging space formed therein and used to locate terminals of a terminal set, two sliding members of a sliding mechanism are movably disposed on two sides of the terminal set in the plugging space, respectively, and each sliding member has a supporting part protruded on a side thereof and extended into the plugging space, and elastic members are abutted between sides of the two sliding members and two opposite sidewalls of the plugging space, respectively; a terminal of a guiding rod is slid along a guiding groove, and other terminal of the guiding rod is inserted through the main body; a push plate of a shielding housing is abutted with the guiding rod, so that a preset electronic card can be stably inserted into or ejected out of the plugging space through the two sliding member.

A connector tray inserted into a connector body in an insertion direction while accommodating an object to be connected includes a tray body configured to accommodate the object to be connected, a tray exterior portion connected to the tray body to be displaceable along the insertion direction, and a push-push mechanism disposed between the tray body and the tray exterior portion in a tandem arrangement and configured to displace the tray exterior portion in the insertion direction between a first position away from the tray body and a second position close to the tray body.

A memory card identification method and a mobile device are provided. The memory card identification method includes: sending an initialization command of a first-type memory card communications protocol to a to-be-identified memory card; detecting whether there is a response in a command pin of the memory card; and identifying the memory card as a first-type memory card or a second-type memory card based on a response status of the command pin.
