5. All About Skimming

How is the fraud performed?
Card information in the magnetic surface of the debit card is
stolen using skimming devices. Furthermore card passwords are
also taken through special mini-cameras or keyboards. Firstly, fake
bank cards is prepared using this information and then
withdrawals from ATMs is performed by using passwords.
For “card copying” type of fraud; a similar looking illegal reader is
used to replace the ATM or SST’s card entry slot. This illegal reader
records the card’s magnetic stripe data when the bank client uses
the card
The look of these illegal readers cannot be distinguished from the
original reader by a regular client. Some of these devices have
internal cameras to obtain the client’s PIN information as well.
Devices without cameras use alternate methods like external
camera, fake keyboard etc. to obtain the PIN information.

M1- DIGITAL
SKIMMING
For protection against illegal digital card readers; even a small
corruption or change in card data renders the data meaningless and
useless. This makes the reader think that no data was read and thus the
illegal copying is prohibited.
A “jammer” type of anti-skimming system easily acts against DIGITAL
SKIMMING

9. Skimming Techniques

M2- ANALOG
SKIMMING
The “ANALOG SKIMMING” method developed by within the last few
years, cheaters can copy card data. In this method, the magnetic stripe
data on the card is recorded as an analog signal, which is later processed
by specially designed software and translated into card data.
Anti-skimming systems with insufficient jammer effect; can’t stop the
“ANALOG SKIMMING” fraud.
DgiWorks AntiSkimming System (DGI-AS) is perfectly effective against
this method.

M3- STEREO
SKIMMING
In this recent but yet undetected method; it is rumored that, two closely
positioned magnetic reader heads operate in tandem, in this method’s
illegal readers. One of the heads records the jammer’s noise, while the
other records the card data distorted by the noise of jammer. Later,
specially designed software helps process these two recordings and
extract the card data.
Although theoretically possible, we don’t think this “STEREO
SKIMMING” method is actually used. However, as stated earlier, this
method is accepted as a threat in related circles assumed to counteract
the effects of jammer based anti-skimming devices.
DgiWorks AntiSkimming System (DGI-AS) is designed to be effective
against this method as well.

Solution
DgiWorks AntiSkimming System (DGI-AS)
The card skimming devices read the magnetic stripes using magnetic heads. The read data is recorded
on the device and later written to another card, thus cloning the original card identity.
The DgiWorks AntiSkimming System, which is developed against card skimming, operates during the
insertion and exit of magnetic card and stops a possible illegal card skimming device from reading the
magnetic stripe data.

ADVANTAGES of DgiWorks AntiSkimming System (DGI-AS)
Distinctive Features
• DGI-AS’s signals that prohibit copying are produced using a propriety technique and cannot be sampled. (The recorded signal cannot be separated)
• DGI-AS’s card entry module is custom built. This stops standard skimming devices to be used.
• DGI-AS’s card entry modules are designed to accommodate any type of detection sensors. Thus, all skimming attacks can also be detected using
sensors as well.
• Advantages
• “DGI-AS Main Control Unit” is designed to be suitable for any upgrades necessary. The upgrades can be made without modifying the “DGI-AS Main
Control Unit”.
• The optional or future features can be applied thanks to the “Extension slot”. Clients won’t spend extra money for new/modified main control units.
• Absolutely identifies card entry and exit correctly.
• Works with “dip” and “motorized” card readers.
• It can automatically revert back to normal mode, after errors are eliminated. (No need for reinstallation)
• Has a clear “operation” and “fault” backlit LCD display.
• Any development can be performed without changing the main control unit.
• Monitoring, software updates and configurations may be performed through remote connection.
• Is easy to install.
• Additional service is not required in cases of card reader faults or replacements.
• Because it only works during card insertion and ejection; it has longer operation life and less failure risks.
• Is lower cost with respect to its competitors.
• Is compatible with all brand and model ATMs available on the market.
• Has a 2 year warranty period, with optional extended warranty.
