RFID technology has been a revolution in inventory management, access control, and logistics tracking of services. However, despite the ubiquity of technology, it presents itself as an enigma to those unfamiliar with RFID technology.

In this blog post, we will take you on a five-step journey to unravel how RFID works. By the end of this post, you will be able to understand how this technology works simply and clearly.

1. Start: Generating the communication link

The first step in understanding what is RFID and how it works is the creation of the communication link between the reader and the tags. This moment is critical in that it allows the basis for data transmission to be established. When the reader emits a radio signal in a specific frequency range, it

One of our client feedback that Wiegand26 has no signal when they use RFID reader SR681.

How to solve it if you also meet this issue ? Please refer to the below solution.

1. Take power from the controller directly, connect four wires, power supply 12V+ GND+D0 +D1

     2. The card reader is powered separately, and the GND needs to be connected to the GND next to the controller D0 D1

Setting the LED light off also turns off the buzzer.  Turning off the buzzer also turns off the LED light

I have 20 of your Yanzeo SR300 scanners and will be making another purchase if we can figure out how to not scan each item. We need to scan the button to engage and scan without having to hit the button for each item. Can you help?

Thanks for your questions. Yanzeo SR300 can perform continuous scanning.Please reset the scanner as below :

Settings -> Card Reading Mode -> Read Tag EPC Number

What is the difference between RFID active reader and RFID passive reader?

We have clients recently asked if our scanner L1100-1D-USB can read interleave 2 of 5 barcodes? 

The answer is Yes .It can read .You only need scan the code as below.

Do you have a RFID reader which can connect on arduino board?

Yes ,we have RFID readers like SA810,SR792,etc which can connect on arduino board to read multiple rfid tag to send a http request with all tag.

Please refer to the detail information for these products.

Question:

We are currently developing a solution on Linux and intend to connect the reader via its USB interface to read RFID tag data.

Could you please confirm if Yanzeo provides any official documentation, SDKs, or code examples to facilitate this low-level communication on a Linux environment? We are particularly interested in libraries or guidance related to:

1. USB Communication Protocol: Details on how the device communicates (e.g., if it uses a standard HID/CDC class or a proprietary protocol).

2. API/SDK for Data Retrieval: Any available ,Python APIs/SDKs that handle the USB interface communication to specifically receive and parse the RFID tag UID and data on Linux.

Any information or links to relevant technical guides would be greatly appreciated as we begin the integration phase.

When the powerful RF performance of 840-960 MHz meets the convenience and flexibility of Android, asset management and retail inventory are revolutionized.
