Another COVID-19 Victim: The Touch Screen

Consumers will look askance at anything they’re asked to touch, leading to a surge in app usage and other alternatives to contacting public screens.

Businesses will have to rethink public touch screens as more customers see shared surfaces as an infection risk, no matter how often they’re cleaned.

ATMs, fast-food ordering terminals, displays in rental cars, airline kiosks and the like will get less use. Some people will carry special pens to tap the screens. Many firms will tout frequent cleaning or even offer free screen protectors to each user.

Expect customers to turn to their smartphones when they are able to. That gives many firms an opportunity to push their mobile apps, which figure to be in heavy demand.

Voice commands and gesture recognition will be popular, but their utility is limited. Voice commands may not work in a crowded, noisy environment. Hand gestures can be inaccurate. But voice-activated speakers will win over more consumers who want to touch fewer surfaces in their homes, a boost for the smart-home market.

At the checkout, look for greater adoption of contactless payments, whether by phone or with debit and credit cards that have embedded chips that allow users to pay by simply putting the card close to a payment terminal rather than inserting it. Contactless payments generally take a few seconds and don’t require a signature, reducing the need to touch a payment terminal. The technology behind tapping a card and mobile payment services, such as Apple Pay and Google Pay, is interchangeable. If a merchant has a terminal that can accept a contactless card, it can also accept mobile payments.

Biometric fingerprint readers will see a steep decline, since they rely on users making physical contact with a device or screen. That raises huge red flags when there’s an infectious disease that is transmitted on shared surfaces. Even routine deep cleaning won’t be able to convince many people to press shared fingerprint readers.

Contact-free facial and iris detection will see a surge in interest. The techniques are commonly used by law enforcement, border control and at airports. India, which relies heavily on fingerprints for its national identification system, is facing the grim reality of a pandemic. The country has had to curb the technology’s use.
