The difference between 1D, 2D and Sick RF tags

In our daily lives, we can easily see a large number of 1D and 2D codes everywhere, and such visual barcodes have become one of the main applications of track and trace technology in various modern automation applications.

With the update and iteration of technology, more and more successful applications of RF tag technology for traceability have begun to appear in recent decades, whether it is FMCG in the hands of ordinary people, or intelligent production in automobile manufacturing, RF tags are favored by users for their rugged and durable, data readable and writable characteristics.

RF tags are so powerful, but RF tags may not completely replace 1D QR codes.

Taking the following figure as an example, the logo on the product can reduce the cost of production and printing links through text + barcode style, as well as terminal reading and recognition equipment, and the general user can also read its barcode information through mobile phones, and the visualization effect is better.

　　For example, some two-dimensional codes can often be seen on the PCB printed circuit board, because the PCB is "every inch of land", so it is necessary to contain as much information as possible in a very small space, the two-dimensional code can not only increase the size of the barcode while having a certain degree of fault tolerance, the use of two-dimensional code here is indeed an economical and reliable traceability method.

　　Automobile manufacturing

The RF tag is sturdy and reliable, and can even be directly entered into the electric pool with the car body and painted, while the barcode relying on metal or paper can be directly damaged. Therefore, RFID technology has accelerated the production cycle, benefited from the fact that the tag information can be written and read, and the whole process of information interaction has also brought great convenience to intelligent manufacturing.

Logistics interaction

It is especially suitable for places where the working conditions are harsh and the barcode will often be worn, and it has two-way information interaction, and the label information can be changed through the handheld PDA. You can even perform advanced operations such as encrypting and locking information.

consumable

Here's a good example of how many of the world's leading FMCG manufacturers have integrated RF tags on the labels of almost all of their products. Interestingly, though, even with the RF tag, they didn't erase the 1D code logo.

　　Expanding on the case of consumer goods, if all products are canceled 1D codes, then customers will not be able to quickly find online product information by scanning the code on their mobile phones when purchasing products. But without the help of RF tags, self-service RFID cash registers and store staff would not be able to count inventory in batches.

In other words, barcodes and RFID are indispensable for the success of these application scenarios.

So what is the positioning of the Sick product line?

At present, Sick has three typical traceability technologies, namely laser, camera and radio frequency technology, and the company has its own R&D team and production line for these three technologies, including a strong visual R&D team in Shanghai. Sick also proposed a concept called More Than Vision, which is more than just vision, that is, to convey a message: there is no single answer to the problem of intelligent traceability. The right one is the better!
