Near-field communication ( NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 centimetres (1.6 in) or less. [ 1] NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections. [ 2]
Flipper Zero. The Flipper Zero is a portable multi-functional device developed for interaction with access control systems. [ 1] The device is able to read, copy, and emulate RFID and NFC tags, radio remotes, iButton, and digital access keys, along with a GPIO interface. [ 2] It was first announced in August 2020 through the Kickstarter ...
Contactless smart card. A contactless smart card is a contactless credential whose dimensions are credit card size. Its embedded integrated circuits can store (and sometimes process) data and communicate with a terminal via NFC. Commonplace uses include transit tickets, bank cards and passports. There are two broad categories of contactless ...
This way the cards become compatible with NFC reader APIs that can only exchange messages in ISO 7816-4 APDU format, with a maximum transfer data buffer size of 256 bytes. Proximity check While the protocol for MIFARE Classic tolerated message delays of several seconds, and was therefore vulnerable to relay attacks, MIFARE Plus EV1 now ...
Zigbee. Zigbee is an IEEE 802.15.4 -based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios, such as for home automation, medical device data collection, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection.
Typical 2G standards include GSM and IS-95 with extensions via GPRS, EDGE and 1xRTT, providing Internet access to users of originally voice centric 2G networks. Both EDGE and 1xRTT are 3G standards, as defined by the ITU, but are usually marketed as 2.9G due to their comparatively low speeds and high delays when compared to true 3G technologies.
A wireless identification and sensing platform (WISP) is an RFID ( radio-frequency identification) device that supports sensing and computing: a microcontroller powered by radio-frequency energy. [1] That is, like a passive RFID tag, WISP is powered and read by a standard off-the-shelf RFID reader, harvesting the power it uses from the reader's ...
The Certified Wireless USB logo. Wireless USB ( Universal Serial Bus) is a short-range, high-bandwidth wireless radio communication protocol created by the Wireless USB Promoter Group, which is intended to increase the availability of general USB -based technologies. It is unrelated to Wi-Fi and different from the Cypress Wireless USB offerings ...
