Chapter 5: 5953 USB DynaKey Migration
Overview
TheNCRRealPOS5953USBDynaKeyisareplacementforits
predecessor,the5953‐Wedge(PS/2)DynaKey,withfeaturesand
advantagesnotpresentintheolderproduct.Thischapterisa
discussionofthosefeatureswithsomeexplanationoftheadvantages.

• DigitalVideoInterface(DVI)cableforvideo
TheNCRRealPOS5953USBDynaKeyimprovesonitspredecessorby
takingadvantageoffeaturesoftheDigitalVideoInterface(DVI)and
UniversalSerialBus(USB)toincreaseflexibilityandconnectivity.
Themajoradvancesare:
• StandardLiquidCrystalDisplay(LCD)interface
• Fullkeyboardre‐programmability
• Addedgeneral‐purposeconnectivityviaon‐boardport
• Flash‐programmablefirmware
• Futureexpandabilityforfingerprintsensormoduleandsmartcard
