QR码和NFC之间的区别

1. QR码：
QR码是一种以二维表示形式存储数据的方式。它也是条形码的一种形式。 1994年开发的QR码由QR扫描仪扫描，以获取其代表的信息。它水平和垂直存储数据。

2.近场通信(NFC)：
NFC是2002年开发的相对较新的技术。它是为使用感应耦合的两个设备之间的通信而开发的。它提供了4厘米内设备的低速连接。设置NFC技术非常简单。它广泛用于无现金支付。

S.No.	QR code	NFC
1.	It was developed in 1994.	It was developed in 2002.
2.	It was developed by Masahiro Hara.	It was developed by Franz Amtmann and Philippe Mangars.
3.	It is only of 1 type.	It is only of 1 type.
4.	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.
5.	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.
6.	It is based on Morse Code technology.	It is based on inductive coupling between antennas of the devices.
7.	It requires line of sight.	It requires proximity (distance between the devices must be less than 4 centimetres, hence the name, Near field).
8.	Only one QR code is examined at once.	Only one NFC is examined at once.
