Identity or identification sensors help us to recognize an object or a person as something unique. Recovery can be done by providing a card or a press kit even through our fingerprint. The technologies we meet in this category are: RFID, NFC, iButton and fingerprint.
- RFID is the early term of Radio Frequency Identification, its performance in Greek is defined as "radio frequency identification". RFID systems are a subset of Automatic Identification Systems. In particular, it acts as a general term of technologies that use radio waves to automatically identify people or objects and is the technological development of barcodes.
- Near Field Communication (NFC) is a standard connectivity technology that is spreading and evolving rapidly with the main purpose of solving several problems, both modern and future. It is a small-scale wireless technology that operates at the 13.56 MHz frequency and transmits data at a rate of up to 424 kbps and is known mainly through its use by the latest smartphones. Its function is based on contact or the approximation of about four to five centimeters of the device that contains the NFC chip in another device that includes the appropriate sensor.
- IButton devices are small, with unique digital addresses worldwide. They use Maxim's 1-Wire communication protocol, they provide the ability to deliver or record data where other products can not, like in very tough and difficult environments. An iButton device is ideal for any application that information should follow a person or object, such as temperature and humidity data, access control, asset tracking, and eCash transactions.
- A fingerprint sensor is an electronic device used to capture a digital image of the fingerprint design. The captured image is called live scanning. This live scan digitizes to create a biometric pattern (a collection of extracted features), which is stored and used for matching.
