Fake Note detection at Cash Desks of Banks and at ATM centers before refilling the ATMs through much needed compatible Equipments
Most of the recent cases of remittance of fake notes to RBI and issuance of fake notes at ATM centers or at cash desk by many leading commercial Banks have been emerging as a result of erroneous understanding on complexity and intricacies involved in the related technology not only that of notes but also of different special purpose machines like sorting machine, counting machines, handy UV/IR equipments, ink pens and manual checking process leading to improper/inaccurate detection most of the time out of the results of not deploying right detection equipments having compatible technology for FICNs detection.
Desk Top Fake Note Detectors/ Sorters -DTFND/Ss (also have been recognized as Mini Currency Validity Verification & Processing Systems –MCVVPSs ), in the international Banking channels have been used for validity verification & fake note detection for exhaustive/detailed scanning of all notes while working on Image Cum Data based technology wherein fake notes are processed in isolation to any other type of segregation and hence have been regarded as only the perfect detection tools as against Note Sorting Machines – NSMs(also have been recognized as Desk Top Sorters –DTSs) which have been primarily used for different types of specialized currency operations of segregating the notes on the basis of set criterion like quality, designs, faces, orientations, denominations etc and pockets have been provided for collecting notes under such set criterions but no special “on line” pockets have been provided for separating fake notes during sorting on different set criterion to isolate the fake notes from all other type of notes.
As you may be aware, NSMs/DTSs do not scan, detect and segregate the fake notes in Isolation of other set criterions by transporting fake notes in the separate and exclusive pocket for collection of fake notes but have been mixed and transported to different pockets as per the normal criterion set in the machine and hence technically becomes impossible to detect the fake notes in isolation to other categories of notes. NSM being incompatible for fake notes detection, have not been used for validity verifications & detection of notes unless those currency types have high end costly security features which are least in ICNs, as the same have been working only on image based technology which though useful for such set sorting process, have not been found good enough for validity verification & detection of fake notes, unlike that of DTFND/Ss-MCVVPSs which sorts the notes in isolation.
We feel the said aspects were absent in the report of HLG, mainly due to merely dearth of such machine in India, as development of such machine needed special R & D efforts separately for each currency types Viz US Dollars, Euro, Sterling pound, as have been carried out by us for detection of Fake Indian Currency Notes to make it possible to check even super fake notes in pure isolation.
The technical aspects on currency notes required to be scanned for purposes of sorting processes; all to gather have been different to that which has been required to be scanned for validity verification and detection of notes. The former involves overall checking of both the faces of notes at very high speed, while as latter involves pixel to Pixel checking of important security features on the notes at the most optimum technical speed for the purpose, as over all scanning have every chances of passing super fake notes for matching the over all features of genuine notes. Super fake notes still bound to have large number of discrepancies with genuine notes if checked pixel to pixel though can match with criterion of genuine notes while over all checking through sorting machines.
As you may be aware that NSMs/DTSs basically are most useful at currency chests or large size Bank branches who are supposed to sort the notes under different categories, have been designed for currency sorting processes on the basis of set criterion like designs, quality, orientations, faces, series, fitness etc, however we feel that NSMs/DTSs have not been designed aptly & exhaustively for accurate fake note detection and hence NSMs/DTSs can not be used as a perfect substitute of DTFND/Ss-MCVVPSsf that are exclusively designed for the specialized process of detection of Fake Notes adding ancillary functions useful at cash desks or at ATM centers.
With deployment of accurate DTFND/Ss-MCVVPSs, the huge investment can be recovered back by avoiding the losses on account of erroneous acceptance of fake notes at cash desks, as also heavy expenditures on consequential legal hassles and lose of Goodwill due to non compliance of strict provisions of law regards to handling of fake notes, though handled unintentionally.
The high speeds of NSMs/DTSs, kill the accuracy of fake note detection as it leaves behind large number of security criterions being unchecked and specifically due to incompatibility of NSMs/DTSs of adapting digital technology which ensures the perfection.
NSMs/DTSs can not check/scan notes pixel to pixel leading consequential inaccurate & imperfect detection of fake notes except for detecting poorly fabricated notes and thus runs with great risks of passing fake notes as genuine or rejecting genuine notes as fake or doubtful.
NSMs/DTSs just throw out large number of doubtful notes with comparatively large number of false alarms and carries very high possibility of passing super fake notes as genuine resulting into issuance of such notes at cash counters or at ATM centers.
Moreover, even highly expensive big sized currency processors used by currency chests and issue offices of Controlling Banks like RBI, with large number of packets used for heavy duty operations are also not able to detect fake notes. The rejected notes are to be manually checked for validity verification & detection of notes. The ration of selected and rejected notes falls on average ratios of 70:30. DTFND/Ss-MCVVPSs could be used to process Sorter rejected notes for detection of fake notes and thus could offer alternative to manual verification of Rejected notes at currency chest with utmost perfection, eliminating the chances of natural human error in adjudication of fake notes.
Fake notes in circulation due to mass mishandling also have been influenced by factors like spoilages, folds, mutilated, physically damaged, soiled, corner fold, tear, tear, holes, missing corner, scribbles, denomination, orientation, formats, adhesive taps, limpness, stains crispiness, identical images, colors, sizes, ink, water mark, paper etc are most likely to be segregated by sorters like that of genuine notes under such varied set sorting criterion instead of getting rejected as fake.
The kind of machines Indian Banks at cash counters needed for the fake notes detection purpose are the machine which can verify not only the images, emblems, portraits, texts, water marks, magnetic and other machine readable features of notes but also checks the physical and chemical properties of security paper, varied types of inks, resins, security threads and other materials used in production of notes, constituting large number of check points out of the interrelated combinations & permutations of varied security features in the notes, by automatic one by one pick ups of single note at a time out of the stacked packet of 100 notes of single or mixed denominations, and processes 100 notes in 1 minute which technically have been regarded as optimum for accurate validation & detection of Fake Notes
The machine meant for detection of fake notes as prime function invariably should be capable of not allowing any fake note to pass as genuine. It is possible only with the detectors specially developed considering the large number of intricacies concerning to Indian notes.
We feel with a view to facilitating the detection of Counterfeit notes, all bank branches/treasuries, at their cash Desks, specifically branches those have been dealing with members of public for acceptance and issuance of notes, ought to be equipped with Desk Top Fake Notes Detector/Sorter or Mini Currency Validity Verification and Processing Systems rather than with NSMs/DTSs
