Say Goodbye To Key Cards, How Can We Enter The Era Of Senseless Access?

Say goodbye to keys and cards: What kind of era of senseless transportation are we entering?

At first, you had to rummage through your pocket for the key before you could swipe the card to enter and exit the community. But now, you only need to swipe it with your mobile phone to pass. We are witnessing a triple jump in authentication methods. Today, digital identity and biometric identification technologies have matured, which is making traditional keys and cards completely disappear from the stage of history. This is not just a change in technology, but also a profound change in our way of life.

Is it really safe to open the door with a mobile phone?

Many people worry that if their mobile phone is lost, their home will be destroyed. In fact, using a mobile phone to open the door is much more secure than a traditional key. The current digital keys use high-strength encryption algorithms. The dynamic token generated every time the door is opened is unique. Even if it is intercepted, it cannot be used again. In addition, the mobile phone itself is equipped with a fingerprint or face lock, which can be used as the first obstacle, which is equivalent to adding double protection to the home. Compared with physical keys that are easily copied and lost, mobile phone keys are more secure.

More importantly, the cloud backup mechanism enables quick recovery when the phone is replaced or lost. You will not be blocked from the door like losing your key. As long as you log in to your account, you can obtain the digital key again. The property owner or landlord can also set the validity period accurately without worrying about tenants or cleaners duplicating keys. This balance of security and convenience is precisely the core advantage of digital identity technology.

Will personal information be leaked if you scan your face to gain entry?

Facial information belongs to the category of private data with the highest level of confidentiality, and many people are wary of facial recognition. In fact, the approach taken by formal systems is to store only the hash value generated by transforming the facial features, not the original image. When you scan your face, this formal system will compare the unique features collected with the feature codes that have been registered in advance. Once the match is successful, it will be released. The whole process is like checking the pattern direction of the fingerprint, rather than storing the photo image of the fingerprint.

What is reassuring is that professional face recognition systems use liveness detection technology to prevent photo or video fraud. Moreover, these data are generally stored in local servers or private networks and will not be uploaded to the public Internet. Compared with the plain text card number written on the access card, the face-swiping system eliminates the risk of the card being copied and peeped. Of course, the key is to choose a qualified and reputable service provider.

What to do if your digital identity expires

Compared with traditional documents, the biggest difference between digital identities is that they are manageable. In a smart community system, visitor permissions can be precisely controlled to a specific expiration time. If your rented house expires, the landlord only needs to adjust the permissions in the background, and your phone will automatically lose its validity. There is no need to worry about the previous tenant hiding the key privately, and there is no need to chase the landlord in the middle of the night to return the deposit and change the access control.

In business scenarios, permissions can be revoked in a very short time when employees leave or when visitors visit. Enterprises do not need to recycle access control cards, and visitors do not need to return cards within a specified time range. Such dynamic permission management makes identity authentication flexible and rigorous, which not only improves security but also reduces management costs. Digital identity truly achieves a state where permissions follow people and security is in line with inner wishes.

How to get in when family and friends come to visit?

No more waiting at the door for long periods of time when friends come to visit you and you're not home. You can open the door remotely through a mobile app, or generate a temporary password and send it to them. This password can be set to be valid only once or for a specific period of time. Some systems even support opening the door after voice call confirmation, allowing visitors to experience the same experience as ringing the doorbell!

For the elderly and children, traditional keys are easy to lose and cards are often forgotten. The digital identity can be bound to the smart watch, and the door can be opened by raising your hand. Fingerprint recognition can also be set up. For the elderly and children with shallow fingerprints, there are now more stable biometric recognition solutions such as vein recognition. Digital identity is making home entrances more inclusive, preventing the elderly and children from being stumped by cold keys.

How to check in at a hotel or B&B without a front desk?

Hotel self-service check-in has become a reality. After the reservation is completed, you will receive a digital room card on your mobile phone. After arriving at the hotel, you do not need to queue. You can go directly to the floor by swiping your phone in the elevator, and then swipe your phone through the door to enter the room. The whole process is as natural as entering your own home. For B&B operators, it not only saves the cost of physical room cards, but also eliminates the risk of room cards being copied or taken away by guests.

This kind of experience is particularly prominent during large-scale conferences or competitions. Participants have multiple digital identities on their mobile phones. When entering different venues, permissions will be automatically switched. The system will determine which area you can enter and what kind of services you can enjoy based on the identity verification results. Intuitive access is reshaping the hotel accommodation experience and giving more energy to the journey itself.

Will cardless and keyless travel become the norm?

From public transportation to office buildings, from the community gate to the elevator floor, digital identity is opening up all physical entrances. We don’t need to remember which card corresponds to which door, and we don’t have to worry about having home keys, office access cards and parking cards downstairs in our pockets at the same time. With a mobile phone or even a face, you can go anywhere where you need to verify your identity.

Behind this trend is the deep integration of the Internet of Things and cloud computing. Access control, turnstiles, and elevators have all become smart terminals on the Internet. What they identify is not the items you carry, but you. When identity verification returns to people’s biological characteristics and behavioral habits, physical media naturally loses its meaning. In the next ten years, cardless and keyless travel will move from early adopters to mainstream and become the infrastructure of smart cities.

With trust, I am sure that you have experienced such a change in your life.
