FAQ about QR lock

1.What is QRLOCK?
Answer: QRLOCK is a door lock unlocked by scanning QR code key which generated from phone Application. And in order to satisfy user's needs and requirements of different service conditions, there are models with password and RF card unlocking functions for option.

2.Does the QRLOCK need to connect the internet? If the lock is off-line, how does it know the QR code key is correct or wrong?
Answer: No, QRLOCK is off-line, but the lock key (QR code) is on-line. After installed the QRLOCK, we need to use QRMASTER App to configure the lock. After the lock is configured, the lock will remember the encrypted ID for this room and current time. Every QRcode key is encrypted with two information: room code and valid time. When guest scan the QRcode to the door lock, the lock decode the QRcode, and check the code and time. If the code is correct and it is in the key valid time now, then lock open; if the room code is wrong or it is not in the key valid time, then the lock won't open.

3.The QRLOCK can be remote controlled?
Answer: There are two concepts of "remote control", one is remote open and close by phone, another is remote transfer the key. Because QRLOCK do not connect with network, so it can't be opened or closed by the remote phone. Only the QRcode key can be remote transferred and deleted.

4. Where can use the QRLOCK?
Answer: QRLOCK includes door lock and access control reader and elevator control reader and other accessory products, which can be used in hotel, apartment, office, residential places, school, storage box and other extended areas.

5. How to get QR code key? Is it complex? Can we use a third party App?
Answer: Email, SMS, whatsapp, Line, Wechat, QQ is supported.

If someone wants to use the third party App to get QR code key, we can supply API SDK interface. 

6. Is the QRLOCK powered by electric or battery?
Answer: The QR door lock is powered by 4 pcs AA batteries, which can be used for about 3-5 months. When the voltage is lower than 4.8V, the lock will alarm to change battery. The QR access control reader and elevator control reader is powered by electric line.

7. How about the warranty?
Answer: warranty is 1 year.

8. If use QRLOCK in hotel, does guest still need to register in reception desk?
Answer: If the hotel do not need to check guest ID and passport, hotel can issue QRcode key to guest directly after received payment, then guest do not need to register in the front desk.

9. Is the QRLOCK safe enough? How about if anyone copy my QRcode?
Answer: A QRcode is only valid for 3 minutes (this valid time can be changed from 1 minute to 30 minutes), do not need to worry about the security, even though someone will take photo of my QRcode, but after a very short time, the QRcode will be invalid. But the changeable QRcode won't make users feel it is complex operation, users just need to press the QRcode or shake his phone to refresh the QRcode.

And the QRcode is encrypted with unique method, it is hard to decode it. And the QR data is saved in Alibaba cloud server, they has strong ability to against hacker attack.

10.Does QRLOCK has other unlocking functions in case no power of the phone, or the elder people who do not use smart phone ?
Answer: Yes, QRLOCK has other unlocking functions. For hotel, we suggest the model QR-05/ QR-02 which can be unlocked by QRcode and mifare card. For home or office use, we suggest the model QR-03MR which can be unlocked by QRcode, mifare card and password.

11.Why QRLOCK is so expensive?
Answer: According to the product material,appearance and function, different models have different prices. We will try the best to save cost, but there is a camera inside, so the cost will be higher than normal RF card lock. The value of a product is not the product itself, but the value that the product can bring to the user. QR lock really means that it can give users more security and convenience, increase the collaboration between human beings, and get more efficient and more social benefits.

12.What are the advantages of QR lock compared with wifi and blue tooth lock on the market now?
Answer: QR lock compared with other mobile phone unlock products, the most significant advantage is that the door lock hardware does not require any network support, also don't need to connect with electric wire, which is convenient for the installation of door locks. Besides, its remote key management function, sharing key function, valid time control function and level authority management function all are very convenient and useful.

13.Is it QR lock have the opening record ?
Answer: Yes, QR lock has opening records. There are 3 types records: 1) Sharing record, you can see who has the right to get the room key. 2) Check on website platform, you can see who got the room key during a specific time 3) Collect from the lock, you can get a record with when and who had opened the lock.
