UniMate series have a audio jack port and focus on strong authentication for mobile devices.

UniToken, UniOTP and UniMate multi-factor authentication devices from SecuTech

The necessary keys are usually too large to memorize ( but see proposal Passmaze ) and must be stored on a local computer, security token or portable memory device, such as a USB flash drive or even floppy disk.

This can be done using a USB token.

The RSA SecurID authentication mechanism consists of a " token " — either hardware ( e. g. a USB dongle ) or software ( a soft token ) — which is assigned to a computer user and which generates an authentication code at fixed intervals ( usually 60 seconds ) using a built-in clock and the card's factory-encoded random key ( known as the " seed ".

As electronic technology continues to become smaller and cheaper, miniature key-fob versions of ( previously ) larger devices are becoming common, such as digital photo frames, remote control units for garage door openers, barcode scanners and simple video games ( e. g. Tamagotchi ) or other gadgets such as breathalyzers. A carabiner, USB flash drive, keyless entry system and Episcopal Church ( United States ) | Episcopalian membership token serving as key fobs.

Yubico offers a small USB token with an embedded chip that creates a OTP when a key is pressed and simulates a keyboard to facilitate easily entering a long password.

A security token ( or sometimes a hardware token, authentication token, USB token, cryptographic token, or key fob ) may be a physical device that an authorized user of computer services is given to ease authentication.

Bluetooth tokens are often combined with a USB token, thus working in both a connected and a disconnected state.

If the Bluetooth is not available, the token must be inserted into a USB input device to function.

In the USB mode of operation sign off required care for the token while mechanically coupled to the USB plug.

; Aladdin Knowledge Systems ’ eToken NG-OTP: The Aladdin Knowledge Systems ' eToken NG-OTP is a hybrid USB and one-time password token.

The Smartcard-based USB Token is widely used, as compared to the normal smart card, which needs card reader and install driver on computer, the smartcard-based USB token does not need any further configuration.

GoldKey is a USB security token that secures a computer login, encrypts local disk drives, and provides two factor authentication to network resources and over the Internet.

In the case of the GoldKey Security Token, a USB device developed by Roger Billings and a team of developers, the token acts as a physical " key " to electronic data.

Any USB memory device can be used as a token simply by storing a secret ( possibly an X. 509 certificate ) on it, but then there is nothing to stop it from being copied.

Some consumers have difficulty keeping track of a hardware token or USB plug.

These hubs and devices do allow more flexibility in the use of power ( in particular many devices use far less than 100 mA and many USB ports can supply more than 500 mA before going into overload shut-off ) but they are likely to make power problems harder to diagnose.

Modern computer buses can use both parallel and bit serial connections, and can be wired in either a multidrop ( electrical parallel ) or daisy chain topology, or connected by switched hubs, as in the case of USB.

A device on the PCI bus or USB is identified by two ID's which consist of 4 numbers and / or letters A to F. The vendor ID identifies the vendor of the device.

The cache is retrieved by connecting a device that has a USB port and that is able to read standard text files.

The microwave would be targeted at office workers and students and can be powered by a computer via a USB port.

Some computer sound cards include a standard MIDI connector, whereas others connect by any of various means that include the D-subminiature DA-15 game port, USB, FireWire, Ethernet or a proprietary connection.

In personal computer peripherals, it has largely been supplanted by other interface standards, such as USB.

Today, RS-232 has mostly been replaced in personal computers by USB for local communications.

However, USB is limited by standard to no more than 5 meters of cable, thus favoring RS-232 when longer distances are needed.

The distinction between external tuner or demodulator boxes ( traditionally considered to be " set-top boxes ") and storage devices ( such as VCR, DVD, or disc-based PVR units ) is also blurred by the increasing deployment of satellite and cable tuner boxes with hard discs, network or USB interfaces built-in.

* USB flash drive, the flash drive based on the computer bus standard by that name

Modern meters may be interfaced with a personal computer by IrDA links, RS-232 connections, USB, or an instrument bus such as IEEE-488.

This " change-on-zero " is used by High-Level Data Link Control and USB.

Hybrid or two-tiered authentication methods offer a compelling solution, such as private keys encrypted by fingerprint inside of a USB device.

In the process, they designed the parallel electrical interface that was to become standard on most printers until it began to be replaced by the Universal Serial Bus ( USB ) in the late 1990s.

Other forms of storage media are further limited by the speed of the storage bus, such as IDE ( PATA ), SATA, USB or Firewire.

* the electrical conditions when a USB-ICC is operated by an interface device-for those contact fields that are not used, when the USB interface is applied ;

USB signals are not incorporated into the connector, but were earlier incorporated into the VESA Plug and Display connector used by InFocus on their projector systems, and in the Apple Display Connector, which was used by Apple until 2005.

The PCMCIA association was dissolved in 2009 and all of its activities are now managed by the USB Implementer's Forum, according to the PCMCIA website.

Much expansion that formerly required a PCMCIA card is catered for by USB, reducing the requirement for internal expansion slots ; by 2011 many laptops had none.

All the functions of add-in card slots can currently be duplicated by USB, including Video, networking, storage and audio.

Interface to a PC is provided by a USB 2. 0 interface though Ethernet could be used as well.

Sound was provided by an external USB amplifier and a pair of Harman Kardon speakers.

A number of monitors with A. b connectors started appearing in the mid-1990s, notably those by NEC, but this was at about the same time USB was being heavily promoted and few devices were available to plug into them.
