Wincor Nixdorf ATMs use 3M Capacitive Touch Screens

Ergonomics and security are the linchpins of efficient cash handling. Touch screens from 3M, the diversified technology company, are used to help provide Wincor Nixdorf ATMs with the durability, strength and ease-of-use that banks demand in widely varying situations world-wide.

Wincor Nixdorf is one of the world’s leading providers of IT solutions and services to retailers and retail bankers. Its success is built on optimising business processes at banks and retail companies - in particular by helping them cut costs and complexity whilst improving service to the end customer. It is a global operation, with a presence in over 90 countries, and dedicated subsidiary companies in 36. Wincor Nixdorf holds second place in Europe and is number 3 worldwide for automated teller machines. Production is also global, with facilities at Paderborn, Germany, and in Singapore, Shanghai and Sao Paolo.

At the heart of its competitive edge is the ability to offer retail banks a broad portfolio for reengineering and automating branch processes. This involves much more than simply supplying POS systems and ATMs. Wincor Nixdorf supplements this with a comprehensive range of analysis, consulting and design to implementation services, covering operations as well as products and solutions.

Ulrich Schäfers is the company’s product manager with responsibility for Banking Division Marketing. He explained: “Our product portfolio includes automated teller machines with various functions – from dispensing and depositing of cash and checks to cash recycling, in which cash that has been deposited can be dispensed again.”

Touch screens play a growing role, with on-screen interaction increasingly replacing soft keys and keyboards. For ATM solution providers like Wincor Nixdorf, there are additional advantages such as simpler localisation and greater flexibility of formats to suit different machines. But these benefits can only be achieved if the screen and touch input work comfortably and securely, round the clock, anywhere in the world.

With 3M touch screens, ergonomics starts with the technology. Capacitive touch screens, such as MicroTouch ToughTouch, are the most popular choice today, offering superior durability, fast and accurate touch performance, excellent light transmission, advanced anti-glare properties and high reliability.

Ulrich Schäfers elaborates: “We fulfil our customers’ key requirements for high availability of their systems with comprehensive services, but most importantly by building dependability into our solutions from the start.”

There are two aspects to this. First and foremost is that of reliability in normal operation: and for Wincor Nixdorf ATMs, ‘normal’ means extremes of climate both in- and out of doors. The latest ToughTouch II touch screens from 3M have an operating temperature of -40 °C to + 70°C, a storage temperature of - 50 °C/+ 85 °C and up to 90 per cent relative humidity, helping the ATMs operate successfully in all parts of the world.

They are popular everywhere with bank customers because they are accurate, responsive and can be viewed clearly under all lighting levels, whether it’s bright daylight, artificial lighting or night-time.

As well as standard models, Wincor Nixdorf is able to offer additional privacy to bank customers by integrating a Vikuiti Light Control Film (LCF) between the ClearTek II capacitive sensor and 4mm backing glass of ToughTouch touch screen. The thin plastic film helps protect transaction information displayed on ATM screens from prying eyes to ensure user confidentiality.

Secondly, touch screens on ATMs need to minimise the impact of abnormal operations such as vandalism, theft and attack. ToughTouch II touch screens have a layer of glass laminated to the underlying ClearTek capacitive sensor, dramatically improving their impact resistance and making them ideal for unattended and high threat environments. These screens already offer high resistance to damage from key scratches or spilled drinks, and the surface is highly resistant to wear on high-traffic areas of the surface. They comply with UL 60950 safety standards, excelling themselves during impact testing without any shattering of glass, and are IP66/NEMA 4 sealable against liquids and other contaminants.

They also offer a superior level of wear resistance over the previous ToughTouch product, making them at least five times more wear resistant than competitive capacitive touch screen solutions on the market. Previous ClearTek products have been tested successfully to withstand more than 255million mechanical touches in a single location without degradation. As well as maximising the ATM’s availability, this high durability also reduces the costs associated with maintenance and recalibration. There is greater convenience for end-users and costs are lower for the bank.

The advantages of 3M’s high-performance, high-reliability touch screens have been clear to Wincor Nixdorf over more than a decade. “We only use ToughTouch”, explained Schäfers, “3M provides a single source for our complete range of screen sizes, but most importantly theirs is the only technology to meet our key requirement; that it can be used both indoors and outdoors.”

The long collaboration with 3M has technical superiority at its core. Schäfers also singles out service as a key factor in the partnership’s longevity, stating, “They provide excellent support to our headquarters in terms of design, development, production and after sales operations”. Such a long-standing relationship is further reinforced by the two companies’ shared values.

According to Wincor Nixdorf’s supplier manifesto: “We collaborate with our suppliers in the same way as our best customers work with us. Our relationship is based on solid business methods and trust in a global, competitive, commercial environment. We share available know-how and integrate suppliers in our internal processes in order to increase the value for all companies involved. Furthermore, we expect our suppliers to be interested in a sustained business relationship and will grasp the initiative in order to contribute actively to improving the process chain.”

3M is continuing to take the initiative by developing ever-improving touch screen technologies. Customers like Wincor Nixdorf will be able to offer increasingly vandalism proof and ergonomic solutions to the retail banking community, helping banks trim their costs and continuously improve their customer service.
