SOFTPRO recommends using capturing devices that operate on Electro-Magnetic Resonance (EMR). There is no better technology to capture "clean" signatures, evidential and high in quality.
Signing with EMR is very ergonomic: Signers can comfortably rest their hands on a tablet's surface without affecting the signature quality.
SOFTPRO hardware partner Wacom holds stunning 80% of the Global Pen Tablet Market*. They provide their components for Electro-Magnetic Resonance under the Label "Feel IT" (prior to 2009 also under the term: "Penabled") to many Third Party manufactures. Their components are integrated into devices with and without LCD screens. . Wacom: Explanation of EMR * Source: Wacom Annual Report 2013, p.16
Back in 2007 Wacom joined forces with SOFTPRO to develop its first tablet primarily designed to capture signatures. The result was the SignPad eSignio (Wacom STU-500). Today SignPads are the preferred choice for all professional users taking signatures seriously.
More than 300,000 Wacom Signature tablets of the STU-series have been installed worldwide by early 2013. They are used in banking, retail, government, telecommunication, postal services, service industry,…

A digitizer overlain on the LCD screen creates an electromagnetic field. When the pen comes in contact with the screen's electromagnetic field, its motion is reflected on the screen as a series of data points. As the pen continues to move across the screen, the digitizer collects information from the pen movement in a process called "sampling."
The digitizer samples "pen events" - units of motion that correspond to data points - per second. These electromagnetic pen events are then represented visually on the screen as pen strokes. The sample rate of events per second of devices with Wacom Penabled Technology inside is for example

Alternative methods to electromagnetic resonance are based on touch response. Different terms are used for this technology. For example "touch-sensitive resistance" or "force sensing resistors". The abbreviation "touch pad” is very common.
With this technology, the sensor consists of a sandwich of two conductive coated plastic film. This sandwich is as a top layer on the signature pad. The action of pressure changes the electrical resistance of the sandwich. The detection of the location and intensity of pressure is thus on changes in distance between the two plastic sheets by the pin.
Signature pads with plastic screen surface may be subject to wear and tear and show ugly scratches
Signature pads and tablets based on this technology tend to degradate faster and show ugly scratches.
The technology is less reliable in demanding environments where high volumes of signatures need to be captured every day. As a consequence some manufacturers exclude touch sensors completly from any warranty. Others exclude the "normal wear and tear" so it remains unclear if a display with scratches sors may be exchanged free of charge or not.
Most manufacturers of these type of devices offer a standard warranty of two years only. SignPads and the Interactive Pen Display DTU-1031 come with a three years warrranty.
This SignPad eSignio (Wacom STU-500) was installed in 2009 at a clerks desk at Caja España. This image was captured in May 2013 when this particular SignPad was in operation for four years. Every working day between 500 and 1000 signatures are captured for transactions and contracts per SignPad at a workstation of a clerk at Caja España.
Other pads are used by agents for contracts and some other major transactions. They capture 50 -100 signatures per SignPad every working day. Lowest usage of SignPads is at branch Manager desks: They use to capture around 50 signatures for contracts on a SignPad.

Santiago Uriel, Technology Vice-Secretary of the Spanish Savings Banks Organization CECA, April 2013:
"Since the first signature has been captured in 2009, more than 300 million documents have been signed via the signature pads and they all look nearly new. In all those years we only had to complain less than 30 – that is a failure rate of less than 0,1%.”
Some Tablets use a combination of active digitizer and touch technology. HP and Lenovo offer the option to order Tablet PCs that leverage Wacom's Reversing Ramped Field Capacitive (RRFC™) touch technology too. They have two sensors: one for pen with electro-magnetic resonance another for inger touch. When using such a device make sure the pen sensor is activated (similar to devices where you can choose between track ball and touchpad as substitue for a mouse).
The S-Pen of all Samsung devices of 2012 and later can distinct 1,024 levels of writing pressure.
The special activize digitizer "Samsung S-Pen" is light and thin (diameter 6.5 mm). S-Pen devices launched in 2012 and later can distinguish 1,024 levels of writing pressure. The pen and digitizer technology of the S Pen is provided by Wacom. Samsung and Wacom signed a capital and business alliance agreement on January, 30 2013. The goal of the alliance is to establish a broad strategic partnership in the smart phone and tablet areas.
In 2011 Wacom's digital pen technology ("Penabled") was integrated in the first smart phone: The "S-Pen" in the Samsung Galaxy Note is an active digitizer from Wacom.
In 2012 Wacom's digital pen technology ("Penabled") was integrated in the first Android tablet: The "S-Pen" in the Samsung Galaxy Note 10.1 is an active digitizer from Wacom.

N-trig's DuoSense® solution is a dual-mode interface, powered by a single device, utilizing both pen and projected capacitive multi-touch functionality. This solution utilizes N-trig’s Digital PencilTM, which enables direct on-screen digital input. The solution was introduced to the Tablet PC market in late 2007. The DuoSense uses a single digitizer rather than having a panel with two layers.
SOFTPRO E-Signing solutions also run machines with built in N-trig DuoSense technology such as
devices running on Windows OS Slates – e.g. Acer Aspire R7-572, Fujitsu Stylistic Q 552, Motion Computing CL 910, Sony Vaio Tap 11, Sony Vaio Duo 11, Sony Vaio Duo 13, Convertibles – e.g. Dell Latitude XT3, Fujitsu Lifebook T 580

SignPads capture data using Electro Magnetic Resonance (EMR). This technology is also build in an increasing number of tablets running on Android or Windows-Betriebssystem.
The benefits of EMR compared to alternative technologies as implemented in SignPads and other tablets are outlined in a whitepaper available to SOFTPRO customers, partners and prospects. Inquire for access to this whitepaper via your contact displayed in the right column of this page.
