Ways to Open Automatic Door without Contact
How does the COVID-19 pandemic changed the way we live? Hands-free environments became a standard within a number of buildings such as offices, public restrooms, hospital operation theaters, public transport, among others. The less you touch objects, the less likely you can get or transfer germs or virus from person-to-person.
While we are still dealing with the pandemic, you and your loved one’s heath is still at risk. In case you cannot avoid not to go out due to important things, the best way you can is to adopt a hands-free environment.
Many people switched to using automatic doors to remove the need for direct contact. With contactless door opening, it’s a lot easier for you to keep your hands clean and virus-free from the entrance to the exit. Depending on your needs, there are several ways on how you can open the door without direct contact. These include:
Contactless Opening with Sensors
Door sensors are among the best ways to make your entrance and exit points contactless.
An automatic door is designed to be opened once its controlled received the activation signal by the sensor. After that, the gear motor will be activated to drive both the belt and alley. If no one is detected within the activation area, then the door closes after a set period of time.
Most automatic doors come with different components such as door operator, maintenance switch, safety sensor, activation sensor, transom, fanlight, fixed door panel, sliding door panel, and lock. Each of these components has a specific function.
Meanwhile, automatic doors are equipped with a supported sensor and an activation sensor.

Support Sensor
With safety sensors, the door panels are prevented from hitting any person or object that is on the door track or near the door. Ultrasonic waves, beam reflection, and photoelectric are common types of safety sensors.
In an ultrasonic wave type, the sensor will keep the detection area under surveillance. It occurs by emitting ultrasonic waves. In a beam reflection type, the door will remain open while the infrared reflection rays detect people. As for the photoelectric type, the door will remain open while the light beam is being blocked between the receiver and transmitters. These two components are installed on both sides of the door.

Activation Sensor
An activation sensor is used to open a door. Activation switches and infrared sensors are two available types of sensors. When choosing the right activation sensor, you need to consider the environment and uses.
In the beam reflection type, the door can be opened by detecting the infrared reflection rays from the people or objects. So, there will be no direct contact on the door involved.

Contactless Opening with Wave to Open (Hand Sensor) Switch
The exact period when the pandemic will end is still unknown. People made their own way to stop the spread of viruses and germs. From using a hands-free soap dispenser to a hand dryer, everyone needs to be more responsible to ensure that the spread COVID-19 virus will slow down.
So, it’s no surprise why people are kept on installing wave to open or hand sensor switch in commercial buildings and even at home. These active infrared devices work by using microburst sensor technology.
With the use of waves to open switch, the spread of germs and viruses can be eliminated as there will no more physical contact. This also helps people to have improved convenience when it comes to moving through the premises.
Depending on the desired application, you can choose from wired, wireless, and wired/wireless hybrid options. Some waves to open switches are available with impact-resistant polycarbonate faceplates and stainless steel. Make sure to choose a switch that is ADA, ROHS, and UL-compliant, and with lead-free construction.
This type of switches is commonly installed egress in building and washroom facilities to have a barrier-free and contactless access and egress. You can go for switches with heavy-duty relay rating and rugged construction to ensure that they are ideal for low-energy automatic doors and interior or exterior doors in commercial, institutional, and industrial facilities.

Contactless Opening with Access Keypad
Access keypad for doors can be connected to a central access control, door locks, deadbolts, standalone pin pads, or IP connected pin pads. There are some instances that the access keypad is paired up with biometrics. That is because the PIN codes can possibly be passed on.
One of the best things about doors that can be opened using access keypad is that they support remote, mobile, and keycard unlocks. In other words, there’s no need for you to open the door just to open it directly.
This type of door opening solution is commonly seen in offices. It can be a primary or secondary access option, together with a security access control system. It may also act as the standalone access point, which is usually installed to backroom storage.
Most of the time, the access keypad is integrated into the security system, where a card can be used to open the door. Since it uses remote, keycard, and other security tokens, the PIN can be shared to other people. For such a situation, you need to ensure that the PIN code is shared to the right people.
In case you want to eliminate the inconvenience of using keycards or tokens to access a building, you can take advantage of authentication access on smartphones. That way, no need for you to scan the card every time you want to enter the premises.

Contactless Opening with Face Recognition Device
For sure, you have an idea of what a face recognition capability is. You can commonly see it on smartphones. Instead of keying in a numerical code or a pattern, you just need to let your smartphone to scan your face. Once it recognized your face, you can then open and use it.
This capability is also applicable to the contactless opening of doors. With the help of a face recognition device, you do not have to touch any part of the door to gain access.
To use this contactless door opening method, it is essential to set up an API service. After that, you can start coding. There are specific codes used to lock and unlock the door. Once the coding is done, you can start adding and storing “trusted faces” images data into the face recognition device.
Meanwhile, you can store a list of corresponding names of each face. In the current frame, make sure to verify if there are faces that are already available to prevent recognition issues.
A face recognition device is another effective way of how you can eliminate the need for physical contact on the door. You can install this device in your living or working spaces for more convenient and safer access.

Contactless Opening with Smart Devices
As you probably know, smartphones are among the devices that you can use to have a smart home. In this type of home, you can access, control your appliances, monitor the safety within your living spaces in a matter of few taps.
Using your smartphone together with near-field communication technology, it’s a lot easier for you to unlock a door. This feature is mostly included in Android phones and other mobile devices. It transmits data securely over short distances.
You can customize the access control app to match your needs. With the use of tap-to-unlock technology, no need for you to use keys to open your door. All you need to do is to swipe your smartphone and manage your access on the go. Additionally, some app does not require active internet access to unlock your door using your smartphone.
Did you know that you can also use your smart speaker to open your door without physical contact? This smart device works by using voice recognition technology. Microsoft uses Cortana, Amazon Echo, and Google Home series, and Apple uses Siri on its voice recognition schemes.
Once the system hears the “wake word”, it activates and then records what you have said. After that, it will send the data over the Internet and to the main recognition service or processing area. Then, the speech file will be sent in the cloud.
With the help of a voice recognition service, the speech will be deciphered before sending a response back to your smart speaker. Since voice recognition utilizes a series of an algorithm, you can expect that the system tends to become familiar with the words and individual speech patterns you use.
