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 More

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 More
