RoHS Certificate of Compliance

Directive 2011/65/EU on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (known as RoHS2) became European Law on 21 July 2011 and will take effect in EU Member States from 2 January 2013. RoHS2 brings a much wider range of equipment into scope but does not introduce any new substance restrictions. RoHS 2 deals with the same six hazardous substances and the same maximum concentration limits as RoHS 1(2002/95/EC).

In addition, RoHS2 is a CE Marking Directive and RoHS2 requires Manufacturers to follow the procedures in Module A of Decision 768/2008/EC which prescribe the conformity assessment procedures that Manufacturers must carry out and the technical documentation they must draw up to demonstrate that their products are RoHS compliant. RoHS2 also includes obligations for all EU Member States to perform systematic market surveillance including “appropriate checks on product compliance on an adequate scale, by means of documentary checks and, where appropriate, physical and laboratory checks on the basis of adequate samples

Innovative Technology Ltd (ITL) already has already established compliance processes and quality management systems for RoHS1, CE mark requirements and for other product regulatory requirements. Innovative Technology has updated all of the documents and the procedures according to RoHS2 and concludes that innovative Technology choose to interact with supply chain to obtain and compile documentation which ITL then evaluates to demonstrate that the finished product complies with the RoHS substance restrictions. This practical approach also explains how ITL evaluates, manages and maintains the supplier materials declarations which are needed for the RoHS2 technical documentation, and any analytical test reports which may also be required.

Innovative Technology Ltd certifies that the following ITL products - NV9 USB, NV10 USB, NV200, NV201, NV11, BV100, NV10, BV20, BV50, SMART Hopper, Note Float, SMART Payout, NG1000. conform to the essential requirements of RoHS Directive 2011/65/EU and conform to the requirements of the EC Directives as below,

2004/108/EC EMC Directive

2006/95/EC Low Voltage Directive

and that the standard and/or technical specifications referenced below have been considered;

BS EN 661000-6-3 2001

BS EN 661000-6-1 2001

(Immunity & Emission standards, residential, commercial and light industry)

EN 60335-2-82

(Household and similar electrical appliances – Safety Part 2-82: Particular

(Information technology equipment – Safety –Part 1: General requirements)

BS EN 60529:1992

All compliant products will be clearly marked on the product and/or packaging and information provided in this certificate of compliance is accurate to the best of our knowledge, as of the date this certification was issued.

SPF™ Technology

What is SPF™ Technology ?

Innovative Technology’s bank note validators use SPF™ technology to validate bank notes. Sensor responses from the validators are digitized to produce a stream of numerical data. SPF™ uses mathematics to analyse this stream of numbers when deciding whether to reject a counterfeit or accept a genuine note. To maintain the industry-leading speed and accuracy of our validation products, it is vital the mathematical algorithms and techniques we use must remain at the cutting edge.


Describing Data

The single most important ingredient in the algorithm is the sensor data collected from genuine banknotes. It is vital to know exactly how genuine bank notes look in order to distinguish genuine notes from counterfeits. Genuine notes come in a wide variety of conditions depending on age and wear (refer to March Technical Bulletin for more details on banknote ageing) so whenever possible, we collect data from as wide a spectrum of notes as possible.

Supporting over 100 different currencies across our range of past and present products has required the collecting, storing and processing of thousands of gigabytes of data. Note data is categorised according to country, denomination, issue, face and orientation so once note data has been collected, a process is required to reduce the information contained in gigabytes of stored data to just a few hundred kilobytes, suitable for downloading onto a validator. This process is known as ‘training’ the dataset to recognise notes.

The algorithms used in SPF™ technology automatically identify the security features within the note data for distinguishing genuine notes from counterfeit and distinguishing different denominations. The algorithms convert the information of the security feature into a mathematical function, which can then be applied to any collected data to test that the security feature exists. If the function is well-designed, applying it to all our genuine note data would produce only a small range of values.  By analysing the distribution of these we can produce thresholds for this small range that account for the uncertainty implicit in our measurements.

This function, along with the thresholds, forms what we call a ‘test’.  When a validator reads the note, we can apply each test to the sensor data. If the resulting value lies within the thresholds, the data has passed the test, and this is taken as evidence that the inserted note is genuine. Conversely, if the value is outside the thresholds, this is taken as evidence that the note is not genuine. Typically, we will construct between 10 and 20 tests, depending on the number and efficacy of the security features on the note in question.

Combining Tests – Boosting

Most people, when given a banknote they suspect of being counterfeit, will run through a mental checklist to determine whether they believe the note to be genuine. 
“Does the paper feel like banknote paper?”
“Is there microtext visible in the strip?”
“Can I see a watermark?” 
“Is the registration between front and back accurate?” and so forth, which are analogous to the mathematical tests.

A genuine banknote may fail anyone of those tests – the paper texture might have changed due to some over-vigorous washing, the watermark may be obscured by a build-up of dirt – so the final determination as to whether to accept the note will be based on a combined impression of the answers to these questions.

SPF™ works in the same way.  If note data fails any specific test that is suspicious, but alone, is not enough. Fortunately there is a mathematical theorem that states that as long as our tests are correct, more often pure guesswork, we can combine them into a test with much better performance. This process of combining multiple fallible tests into a single high performance algorithm is called Boosting.  In essence, each individual test is allowed to vote on whether to accept the note, giving each test a different amount of influence depending on how well it performed during training.

Validating the Validation

When we have our collection of tests the dataset is ready for testing.  When training the dataset, we withhold a proportion of the data from the training process.  After training, the tests are applied to that unseen data, a process known as cross validation. Only when the accuracy rate of this cross-validation reaches the required standards will the dataset be released to customers.
