SECTION 1: DESCRIPTION OF THE SYSTEM
The uDynamo is a magnetic stripe secure card reader authenticator (SCRA) designed to allow all
three tracks of financial and other cards such as AAMVA to be read using the multimedia audio
connector of a mobile devices such as iOS and Android devices. The uDynamo interfaces to
mobile devices through the audio head set jack and communicates with the host device through
the microphone input and the audio output signals.
In addition to the audio interface, a USB interface is provided to allow the uDynamo to charge its
internal, rechargeable battery, and to allow the uDynamo to interface with Windows or OS X
based computers which provide a host USB interface.
The uDynamo is powered by rechargeable internal Lithium-ion batteries that are not replaceable.
The reader is designed to draw extremely low current in when operating with the audio interface
allowing the device to operate on batteries for extended periods. When operating from USB, the
device is powered from the USB bus and will charge the battery at the rate allowed by the host
USB interface.
Card data are encrypted within the reader prior to being sent to the host. The host has no
knowledge of the decryption key ensuring that cardholder data are protected. This also provides
the merchant the confidence that their customer data cannot be compromised by malicious
software on their systems. To allow verification of the transaction, a partly obfuscated account
number, cardholder name and card expiration date are sent to the host as clear text where they
may be displayed, retained, or become part of a receipt.
The uDynamo is a MagneSafe reader that is fully compliant with MagTek’s V5 protocol and
includes MagnePrint®, a powerful anti-skimming technology that can detect whether a card is
the original card, or is a fraudulent copy.
The uDynamo is capable of reading all three tracks of ISO 7813 Magnetic cards containing
financial and AAMVA data found on driver’s licenses.
