Near Field Communication & Optical Character Recognition

Near Field Communication(NFC)

Near field communication (NFC) is a set of standards for smart phones and similar devices to establish radio communication with each other by touching them together or bringing them into proximity, usually no more than a few inches.

Present and anticipated applications include contactless transactions, data exchange, and simplified setup of more complex communications such as Wi-Fi. Communication is also possible between an NFC device and an unpowered NFC chip, called a "tag"

A range of devices can use the NFC standard and can be considered either passive or active, depending on how the device works. Passive NFC devices include tags, and other small transmitters, that can send information to other NFC devices without the need for a power source of their own. However, they don´t really process any information sent from other sources, and can´t connect to other passive components. These often take the form of interactive signs on walls or advertisements.


Knowing what near field communication is and how it works is one thing, but while it may seem like a novel idea in theory, how exactly will it benefit you? If you're considering upgrading to a NFC enabled smartphone, already own one but have never used the technology, or are simply curious to learn more about its advantages, read on to find out why NFC technology is gaining in popularity.

Optical Character Recognition (OCR)

Optical Character Recognition, usually abbreviated to OCR, is the mechanical or electronic conversion of scanned or photoed images of typewritten or printed text into machine-encoded/computer-readable text. It is widely used as a form of data entry from some sort of original paper data source, whether passport documents, invoices, bank statement, receipts, business card, mail, or any number of printed records. It is a common method of digitizing printed texts so that they can be electronically edited, searched, stored more compactly, displayed on-line, and used in machine processes such as machine translation, text-to-speech, key data extraction and text mining. OCR is a field of research in pattern recognition, artificial intelligence and computer vision.

It can be used for

  • Data entry for business documents, e.g. check, passport, invoice, bank statement and receipt
  • Automatic number plate recognition
  • Automatic insurance documents key information extraction
  • More quickly make textual versions of printed documents, e.g. book scanning for Project Gutenberg
  • Make electronic images of printed documents searchable
