QR code is a way of storing data in the form of two-dimensional representation. It is also a form of a barcode. Developed in 1994, the QR code is scanned by a QR scanner to get the information it represents. It stores data horizontally as well as vertically.

Near Field Communication (NFC) is a relatively newer technology developed in 2002. It was developed for communication between two devices using inductive coupling. It offers a low-speed connection to devices within 4 cm. It is very simple to set up the NFC technology. It is widely used in cashless payouts.

It is only of 1 type.It is only of 1 type.
It is a type of 2D barcode or printed representation of data that can be scanned for data retrieval.It is a communication protocol for communication between devices (electronic) within a distance of 4cm.
It is used in supermarkets, hospitals, cinema or by individuals etc. for transfer of data (sharing contacts, photos, videos and other documents).It is used as identity cards, as key cards and as a method of contactless payments and mobile payments in various sectors such as retail, automobile, cinema etc.
It is based on Morse Code technology.It is based on inductive coupling between antennas of the devices.
It requires line of sight.It requires proximity (distance between the devices must be less than 4 centimetres, hence the name, Near field).
Only one QR code is examined at once.Only one NFC is examined at once.
Less secure than NFC.More secure than QR code.
