What are the differences between Barcode and NFC?
Let us understand the concepts of Barcode and Near Field Communication (NFC), two different technologies used for data transfer and identification in various applications. Barcode A barcode is a machine-readable code consisting of parallel lines of varying widths and spacing that represents data in a visual format. A barcode reader decodes the data contained in the barcode and sends it to a computer system. The barcode reader produces a beam of light or laser to scan the barcode, which reflects off the barcode image. A light-sensitive detector in the reader identifies the barcode by recognizing special bars ...
Read MoreWhat are the differences between Barcode and QR Code?
Let us understand the concept of barcode and Quick Response (QR) code.Bar CodeA bar code reader decodes the data contained in the barcode and sends it to the computer. It produces a beam of light or a laser beam to read barcodes which is reflected by the bar code image. A light sensitive detector which is present in the reader identifies the bar code by recognizing special bars on both ends of the image. With the help of these special bar’s reader is able to identify whether the bar code has been read right side up or upside down.Once a ...

Read MoreWhat are the differences between RFID and Barcode?
Let us understand the concepts of Radio-Frequency Identification (RFID) and Bar code before learning the differences between them.Radio-Frequency Identification (RFID)RFID is a small electronic device which has a small chip and an antenna. This chip generally carries 2, 000 bytes of data or less.It works the same as a bar code or a magnetic strip on the back of a credit card or ATM card providing a unique identifier for the object. The RFID device is just like a barcode or magnetic strip used to scan to retrieve the identifying information.It is one of the wireless non-contact uses of radio-frequency ...
Read MoreWhat are the differences between QR code and NFC?
Let us understand the concepts of QR code and Near Field Communication (NFC).QR CodesQR code is called "Quick Response", it allows us to encode or store over 4500 characters in a two-dimensional bar code.These codes are the "square barcodes" that were initially developed and used in Japan.The main aim of the QR code is to store the information in such a way that the machine (scanner) can be able to read the data present in the code.Uses of QR codesQR codes can be used for storing data like −Simple textPhone numbersOnline conferences via zoom appOnline one time passwords(OTP)Online accounts authentication ...
Read MoreDifferentiate between Fastag, Bar Code, QR Code and NFC.
Let us understand the concepts of Fastag, Bar code, QR code and Near Field Communication (NFC).FastagFASTag is an electronic scanner system used for toll collection in India, which is operated by the National Highway Authority of India. It is based on radio frequency identification (RFID) technology. FASTag is fixed on the windscreen of vehicles. FASTags does not have any expiry date. They can be recharged at any time.Working of FASTag systemVehicles with FASTag enabled do not have to stop at toll gates where charges are deducted from the prepaid or bank account when the vehicle is moving. The drivers do ...
