As COVID-19 Challenges Retail, Can Point of Sale Technology Clean Up?

As COVID-19 Challenges Retail, Can Point of Sale Technology Clean Up?

As public places including non-essential shops begin to re-open globally, a technological revolution has quietly taken over the traditional marketplace. Enabled by rapid advances in wireless data and spurred on by a move away from cash payments by consumers, Point of Sale (POS) technology has emerged as a major global industry. With this sector forecasted to be worth over $125B annually by 2027, we can expect manufacturers in this field to continue to expand and innovate.

The fastest growing segment in this market is expected to be the handsets and terminals used by superstores, restaurants and sole traders alike. These mobile terminals have a host of benefits over older, bulkier form factors, offering users portability, flexibility and the option to process payments anywhere there’s mobile data.

But this flexibility also comes with an increased vulnerability to wear and tear and environmental damage. If these systems are exposed to humid environments or wet conditions, there is a significant risk of failure of the device.

The COVID-19 Pandemic has brought some of these challenges to the forefront. Not only is there a greater demand for payments to be taken outside, but devices now need to be regularly cleaned and disinfected after handling, increasing the chance of liquid ingress and damage to electronics.

The failure of POS devices from these kinds of liquid damage is expensive. A failed POS terminal can incur costs to the manufacturer/service provider several times over:

  • Since POS systems are often sold as part of a comprehensive service where providers take a small cut of all transactions, they begin losing revenue as soon as a device fails.
  • Providers may sell their devices and services with a guarantee that faulty terminals will be repaired or replaced. As well as the obvious repair or replacement costs, there are also administrative and handling costs for the return of the faulty device.
  • Customers frustrated with unreliable hardware are likely to switch to service providers they feel are more dependable, costing companies revenue and damaging brand reputation.

These pain points for the provider are felt all across the POS customer base, regardless of scale. Customers with large numbers of POS terminals that see a high failure rate in its payment devices will quickly move on to a POS service provider they view as more reliable, costing the original provider a substantial loss in revenue. And although the loss of revenue from the churn of a dissatisfied sole trader will be less impactful for the POS provider, in an era where brand reputations can be destroyed in a single tweet, the reputational damage caused by an unreliable device should not be underestimated.

This is why we are using our P2i technology to protect POS terminals. Our plasma nano-coating technology bonds a microscopically thin polymer layer directly to the entire surface of electronic components, protecting them from liquid and corrosion damage. Unlike other water protection methods, such as crack-prone conformal coatings or mechanical seals and gaskets, nano-coatings don’t add weight or bulk to the POS terminal, provide continual protection to a treated device’s electronic components for the lifetime of the product, and the protection isn’t compromised when the outer body of a POS terminal is knocked or damaged. Moreover, P2i’s solution is also proven to show no deterioration in levels of protection following rigorous testing with isopropanol; also known as isopropyl alcohol (IPA), commonly used as an antiseptic or disinfectant; meaning manufacturers and customers can be confident that they can properly clean their POS terminals without risk of damaging the device.

With COVID-19 transforming retail and accelerating adoption of new technology, P2i is working with manufacturers to ensure their hardware is reliable and ready to meet the challenges of a new era of payment technology.

The automotive printed circuit board (PCB) market is already expanding rapidly, thanks largely to reduced hardware costs, but over time we are likely to see more electronics being fitted into both new and second-hand vehicles, which will drive further growth. Consequently, the global automotive PCB market is expected to reach more than $14 billion during 2018-2024 according to a new report available from

We also anticipate this market will continuing to expand in the future. Features like rear-facing cameras and automated parking are becoming standard. Markets for applications from vehicle lighting and safety to powertrain components and interiors are all maturing – and the growth this brings will drive further expansion in automotive PCBs.

Consumer expectations of the reliability and safety of these components are increasing too. In part, this is driven by manufacturers looking to differentiate around the reliability and safety of vehicles. The arrival of autonomous vehicles on our streets will serve to raise the reliability and safety stakes and the need for more reliable PCBs – even further.

We are already seeing stringent standards in place governing automotive PCBs: from IPC-6011 which defines the generic performance specifications for PCBs to AEC Q100, which delivers failure test qualifications for integrated circuits. Moreover, product recalls in the automotive industry are expensive, which further pushes the need to ensure PCB vendors deliver maximum performance and reliability. Additionally, the need to protect the PCB rises with the number on each car.

Modern vehicles are designed with increasing numbers of electronic components which are vital to their day-to-day function. As more electronic components become integral to vehicles, there is a growing requirement to improve the reliability of component: effectively to match the dependability of more traditional, less electronics-dependent vehicles, which have fewer points of failure, by protecting the PCBs from damage. In pursuing this aim, manufacturers  put an ever-higher premium on the integrity and lifespan of PCBs.

All this is enough to make the need to protect boards an imperative for any automotive manufacturer. Yet, the trend to miniaturisation of components makes achieving this protection ever more challenging. It is, therefore, becoming increasingly important that manufacturers integrate the latest water protection methods to protect these components and help ensure longevity.

Unfortunately, there are weaknesses with current water protection methods. The most commonly used are conformal coatings, which struggle to protect the entire PCB. Connectors cannot be protected as the coating is too hard and thick. Spray coatings, brush coatings and CVD (chemical vapour deposition) coatings also age poorly, cracking and delaminating over time. Gaskets and sealed enclosures are commonplace modes of protection. However, they tend to deteriorate through vibration and natural aging.

These traditional approaches to water protection also struggle to manage miniaturised boards. This is a big problem given the trends we see today. More components and functions being added into cars inevitably leads to a reduction in the space available for each circuit board, and therefore also to a focus on miniaturisation. This often makes protecting the boards more difficult.  Moreover, the more densely packed the PCBs inside a console or engine, the less space there is for physical seals.

Finally, more PCBs mean more connectors for communication. As these cannot be protected by traditional conformal coatings, they are often poorly protected, or need mechanical seals built into the connectors themselves.

Finding a Way Forward

Today we see nano coatings emerging as the ideal solution to these challenges. Typically, they are ultra-thin. By applying them, instead of thicker coatings, manufacturers avoid the problem of underfill behind the board. They can protect every part of the PCB including connectors and they do not crack and delaminate with age. The coating is chemically bonded to the surface of the PCB, meaning that it becomes part of the product and will last for the board’s lifetime.

From the miniaturisation perspective, nano coatings don’t have the same challenges with space limitations that traditional sealants have. Today, the use of nano coatings is growing as an effective way to protect PCBs. Given the increasing integration of electronics with vehicles and continuing technical innovation in the field of nano coatings, we can expect the use of nano coatings in the automotive industry to continue to increase.

The ongoing growth of the drone market looks set to continue, with 7.5 million drones projected to be taking to the skies in Europe by 2030.  Gartner analysis shows huge global uptake in construction, emergency services, insurance and logistics. For drone deliveries to be commercially viable, however, flight time and range needs to be maximised and downtime for recharge and repair reduced.

Reliability requirements for large fleets of wide-ranging urban delivery drones are stringent, as they will be constantly exposed to changing weather patterns. Governments will regulate forcefully to ensure manufacturers and operators of delivery drones can guarantee fleets are safe and reliable.

With drones now poised to be rolled out at scale for frequent, long-term autonomous operation, electronic components emerge as a likely point of failure. Ambient humidity, rain, salt fog and other atmospheric contaminants pose a high risk of electrical shorting and corrosion.

The form factor of the now-ubiquitous rotor drones makes comprehensive waterproofing challenging. Internal seals or external “wetsuit” style waterproofing adds weight to devices and limits maximum range, flight speed and payload. Thick conformal coatings painted or sprayed directly onto circuit boards and components keep water out but can’t be used on connectors, because they inhibit electrical conductivity, and are prone to cracking and delaminating.

This is where plasma nano-coating technology is the perfect solution. Already widely used in consumer electronics, the technology uses plasma to bond an invisibly thin, ultra-light layer of polymer to the surface of the electrical components.  Nano-coatings allow for full reworkability and repair of drones, but unlike other water protection methods, provide continual protection to a treated device’s electronic components for the product lifetime. And in contrast to mechanical solutions, the protection isn’t compromised when the outer body of a drone is knocked or damaged. The microscopically thin coatings also add up to huge weight savings, with a nano-coating protection on a mid-sized drone weighing as little as half a gram, compared to 170 grams or more for a “wetsuit” or similar barrier.

In fact, some commonly used waterproofing methods can add to the weight of a drone by as much as 12%. Research has shown that the weight of a drone correlates with expected battery life, with performance declining almost in direct proportion to increasing weight. A best-case improvement of 12% battery life per charge for a single drone is already impressive, but when scaled up across a global fleet the savings become staggering. With multinational retailers and logistics companies already investing heavily in drone technology to secure dominance over a rapidly emerging market, the rewards of utilising high-tech solutions like nano-coatings are too big to ignore.

That’s where we feel we fit into the picture at P2i, thereby helping increase the range, battery life and maneuverability of the product.

The ongoing roll-out of this technology is another reminder that as advances in battery technology and AI bring the dream of a global society revolutionised by drones to reality, manufacturers shouldn’t ignore the massive potential of nanotechnology to help drones transition from niche curiosity, to indispensable part of the global economy.
