Barcode technology in healthcare. Barcode technology in healthcare is the use of optical machine-readable representation of data in a hospital or healthcare setting. Dating back to the 1970s, there has been a continual effort among healthcare settings to adopt barcode technology. [1] In the early 2000s, published reports began to illustrate ...
Optical mark recognition ( OMR) collects data from people by identifying markings on a paper. OMR enables the hourly processing of hundreds or even thousands of documents. For instance, students may remember completing quizzes or surveys that required them to use a pencil to fill in bubbles on paper (seen to the right). A teacher or teacher's aide would fill out the form, then feed the cards ...
Automatic identification and data capture ( AIDC) refers to the methods of automatically identifying objects, collecting data about them, and entering them directly into computer systems, without human involvement. Technologies typically considered as part of AIDC include QR codes, [1] bar codes, radio frequency identification (RFID), biometrics (like iris and facial recognition system ...
The proximity card coil of an electronic fare collection system. A proximity card or prox card [1] also known as a key card or keycard is a contactless smart card which can be read without inserting it into a reader device, as required by earlier magnetic stripe cards such as credit cards and contact type smart cards. [2] The proximity cards ...
Optical character recognition. Optical character recognition or optical character reader ( OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene photo (for example the text on signs and billboards in a landscape ...
ShotCode is a circular barcode created by High Energy Magic of Cambridge University. It uses a dartboard -like circle, with a bullseye in the centre and datacircles surrounding it. The technology reads databits from the datacircles by measuring the angle and distance from the bullseye for each point. ShotCodes are designed to be read with a ...
Radio-frequency identification ( RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number ...
ELM327. The ELM327 is a programmed microcontroller produced for translating the on-board diagnostics (OBD) interface found in most modern cars. The ELM327 command protocol is one of the most popular PC-to-OBD interface standards and is also implemented by other vendors. The original ELM327 was implemented on the PIC18F2480 microcontroller from ...
An optical reader is a device that observes visual information and translates it into digital information, [1] as found within most image and barcode and matrix-code scanners. An example of optical readers are marksense systems for elections where voters mark their choice by filling a rectangle, circle, or oval, or by completing an arrow.
Multiline optical-character reader. A multiline optical-character reader, or MLOCR, is a type of mail sorting machine that uses optical character recognition (OCR) technology to determine how to route mail through the postal system. MLOCRs work by capturing images of the front of letter-sized mailpieces, and extracting the entire address from ...
