What is the difference between a two-dimensional code access control system and a two-dimensional code access control card reader?

There are a lot of small partners who don't know the difference between the QR code reader and the two-dimensional code access control. It takes a lot of effort and finally gets the answer from the little brother of the R&D department.

1. First, the two-dimensional code access control is composed of a two-dimensional code card reader + two-dimensional code access controller + door opening software;

The QR code access control system is equivalent to a person, composed of a variety of complex parts, such as limbs, body, brain, etc., is a complete and operational system.

2, the QR code access control system does not have a two-dimensional code access control card reader, it is not a complete and mature two-dimensional code access control system, just like no camera without a camera, can not perform work.

3. Summary, the two-dimensional code reader is a part of the two-dimensional code access control; and the two-dimensional code access control is composed of a two-dimensional code reader and access control + open door software; if the two-dimensional code access control is like a person, Then the QR code access control card reader is the human eye. The QR code reader reads the data and transmits it to the access controller, which processes the data by the access controller.

Common questions:

Q: Can the QR code access control card reader work offline offline?

A: No, it's just a transfer machine, it doesn't exist or it can work offline.

Q: The encrypted access control QR code can be recognized by the QR code access control card reader?

A: The Seberus QR code access control reader can recognize the encrypted access control QR code, which is transparent transmission and reads what is transmitted.

Q: How many communication methods does your card reader support?

A: Seberus QR code access control card reader, support Wiegand, RS458, RS232, communication.

Q: How many recognition methods does your reader support?

A: QR code, IC card, CPU card, NFC, password keyboard.

Q: Can your QR code reader be installed in an elevator or outdoors? What about the gates?

A: Yes, the Sebres QR code reader is designed by an industrial designer. It can be used for embedded gates, elevators, or outdoors.
