What are the differences between Barcode and NFC?

Let us understand the concept of Barcode and Near Field Communication (NFC).

Bar Code

A 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 bar code by recognizing special bars on both ends of 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 barcode is identified by a bar code reader it decodes it and converts the individual bar patterns into numeric digit code that can be read by computer, After decoding the barcode it enters that data into computer as a text.

Given below is the sample image of bar code −

Near Field Communication (NFC)

NFC operates within a radius of about 4 cm and also provides a wireless connection between your device and another device. It allows for two-way communication, with both devices involved and is able to send and receive information. This NFC connection does not depend on Wi-Fi, 3G, LTE or otherwise, and it doesn't cost anything to use.

Advantages

The advantages of NFC are as follows −

• Safety

• Versatility

• Convenience

• Used for multiple applications

• More security when compared to other technology

• Compatibility with RFID technology

Disadvantages

The disadvantages of NFC are as follows −

• The company agreement is required to Use

• Works for shorter distance

• Slow data transfer rate

• Not advantage for users

• Power consumption is more
