My Suggestions

I am surprised the Quora folks didn’t focus on masks. Whether handmade cloth or 3d printed, these are selling fast.

An unscientific survey of other successes says: glaziers, window installers.

Why? Because businesses are now taking pickup orders. This means keeping the customer outside, and keeping workers inside. It’s time to install some kind of walk-up window, or a counter that faces the outside.

An add on: roll down security doors.

Touchless is the keyword. Germophobia has gone mainstream.

Touchless automatic fixtures and appliances. “No contact” is the term of the year, and these touchless products already exist. Everyone know the touchless hand sanitizer dispenser that squirts out some alcohol foam, and the basically same machine that does the same for hand soap. There’s also the paper towel dispenser and touchless hand dryer. We also know the no-contact urinal and toilet. These appliances are expensive, and also need installation. So business should be good.

There are also potential new products, like an automatic sanitation machine to clean out the toilet area. This already exists in some cities that have kiosk restrooms.

Touchless vending machines. Yes, they exist, but are a niche product. Expect them to become viable in the future. Material and operation costs are lower than for traditional vending machines.

Related to both of these above is NFC and no-contact payment and identification systems. NFC means near field communication, and is a form of RFID which means radio frequency identification. Most credit cards and many mobile phones have “nfc” built into them. This allows for features like gas station “fast pass”, payment through Google pay or Apple pay on credit card machines.

The same technology is used to create electronic door locks. These things are pretty expensive, but allow for smaller businesses to implement lock systems that work like a hotel: you use key fobs or cards, or a smartphone with NFC, and each key is unique. These will require installation, software, and training.

Infrared technology is used to make touchless buttons. These often include a mechanical button, but add an infrared heat sensor that detects a hand placed near the button. This is useful for automatic doors that are opened with a button press. The button can be upgraded for less than $20. Sourcing and installation can command a lot more revenue!

If you don’t have much capital, you can use a 3D printer to fabricate plastic door handle pullers. These are key fobs that are shaped like hooks, and allow you to pull the door without touching the handle. Profits are small, but, the market does exist for them on online sales sites like ebay and mercari.

Similar to buttons are touch-free or no-touch light switches. These replace light switches, which are fomites, or surfaces that get touched and pass on germs, and have some potential. Most homeowners don’t even know these things exist, and they are not hard to install. These are not the same as wi-fi wall switches, which cost more and are touched. There are basically two brands: an old Honeywell, and a new “adorne” that costs a lot.

Closely related are the motion-sensor switches, which are common in commercial restrooms. These are more sensitive to motion, so anyone walking in will cause the switch to activate, and then, after several minutes, will shut off. Some switches have an additional timer feature. Are these really worth it, or an annoying add on? It’s hard to say, but given the times, the touchless aspect is a selling point.

Some pens nowadays have a rubber “stylus” for use on mobile phones. They can work to press touch screen ATMs, elevators, and other touch-screen systems. While this has dubious utility, because you could use a tissue to protect yourself, it’s still a selling point, if you have these pens in your store inventory.

A similar “touchless” technology that has existed for decades is the touchless trash can with the lid that flips up. If you already sell them, you can emphasize “touchless” to update their relevance.

Touchless thermometers that read from the forehead have gone up in price into the $60 range, so it’s too late to make a quick buck on these, but there should be strong demand as long as stores and buildings require temperature checks. Odds are demand will increase even more as businesses “open up”.

A workaround is to use a no-contact thermometer attachment for a multimeter.

What’s the technology underlying no-touch devices?

The main one is the motion detection switch, called a pyroelectric infrared sensor, or PIR motion sensor. These detect warmth that’s moving in front of the switch, making them very good at detecting mammals! The switch is a sensor with a lens, and support circuitry to send an “on” signal. You need extra logic to decide how long to keep the device “on”.

Another technology is a sonar proximity detector. It sends out an ultrasonic tone, and determines the distance of an object that’s reflecting the sound back to the sensor.

Yet another is capacitive proximity sensors. These work somewhat like the touchpads on computers, and don’t need to be touched, but are generally designed to be touchable, or placed behind a touchable surface. They’re used to detect things like the presence of water in a tank. These can be used to create touchless products, but aren’t the ideal.
