条形码和NFC之间的区别

1.条码：
条形码是一种使用线条和空格存储数字数据的方法。它以计算机可读格式存储，可以由条形码扫描仪使用激光读取。它可以向前和向后读取。该技术在商店中用于跟踪所购买的物品。它也广泛用于其他领域，例如医院，邮政和汽车租赁业务。

4.	It is a way of storing numbers in a printed and computer understandable format.	It is a communication protocol for communication between devices (electronic) within a distance of 4cm.
5.	It is used at stores for tracking all purchased items, in hospitals for tracking the records of patients, in rental cars business and tracking of airline luggage, mails and nuclear waste.	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 barcode is examined at once.	Only one NFC is examined at once.
