!
Thank  you  for  purchasing  the  Fingerspot  FlexCode  SDK!
FlexCode   SDK   is   very   simple   and   easy   to   use   in   accordance   with   the   demands   of   your   applica?on   needs.   FlexCode   SDK   provide   more   advanced  solu?on,  suitable  for  those  who  need  more  freedom  in  crea?ve.  The  func?ons  in  FlexCode  SDK  are  not  too  basic,  the  func?ons   concept   are   instant,   you   simply   call   the   func?ons   required   for   registering   and   verify   fingerprints   then   FlexCode   SDK   will   do   registra?on   process  and  verifica?on  process  without  you  need  to  be  directly  involved  in  it  .  The  registra?on  process  will  produce  a  fingerprint  template   in  a  text  format  that  is  easy  to  stored  and  distributed.  If  you  want  to  iden?fy  a  finger,  the  templates  is  used  to  compare  the  fingerprints  are
!
scanned.  You  will  receive  the  results  of  the  verifica?on  whether  the  same  finger  or  not.  FlexCode  SDK  greatly  save  your  ?me  to  integrate   fingerprint  technology  into  any  applica?on  required  .
The  advantages  and  the  flexibility  you  get  on  FlexCode  SDK:
•  Template  in  a  text  format  that  is  easily  stored  and  distributed.  Template  secure  because  it  is  encrypted  with  your  own  password.
•  The  balance  between  speed  and  accuracy  of  the  kind  currently  compares  with  an  average  of  up  to  200  fingerprint  templates  per  second.
•  Use  mul?ple  devices  in  a  PC.
•  Display  the  fingerprint  image  is  integrated  into  the  applica?on.
•  Supports  verifica?on  1  to  1  and  1  to  N.
!!
•  Opera?ng  system  Windows  Xp  /  Vista  /  7  /  8  32  &  64bit.
•  Designed  for  the  Digital  Persona  U.are.U  fingerprint  reader.  Compa?ble  devices  are  U.are.  U  4000B  and  U.are.  U  4500.
INSTALLATION  FLEXCODE  SDK
1.
Make  sure  your  computer  does  not  installed  any  U.are.U  driver.  If  there  are,  uninstall  it  first.  Then  restart  your  computer.
2.
Run  the    setup  file  FlexCodeSDKSetup32.exe  or  FlexCodeSDKSetup64.exe.
!!
3.
Follow  the  steps  on  the  screen  to  install  the  SDK  FlexCode  and  U.are.U  driver.  Then  restart  your  computer.
4.
Plug  the  device  to  the  USB  port  of  the  computer.
FINGERPRINT  TEMPLATE
Template  is  a  digital  form  of  fingerprint  pacerns  generated  from  the  fingerprint  registra?on  process.  This  template  is  a  text  format  (string)   so  it  is  easy  to  be  stored  and  distributed.  Template  instead  of  fingerprint  images.  Templates  can  not  be  converted  into  a  fingerprint  image.
Template  is  unique,  meaning  that  if  the  same  finger  repeatedly  registered  then  generates  the  templates  are  different.  Templates  should   not  be  changed  because  it  would  lead  to  the  failure  of  the  verifica?on  process.  Make  sure  the  string  is  stored  template  perfectly  without
!!
any  addi?on  or  subtrac?on.  There  is  only  one  way  to  compare  the  scanned  finger  on  the  device  to  the  registered  template  by  using  the   verifica?on  func?on  provided  by  FlexCode  SDK.
FINGERPRINT  REGISTRATION
Fingerprint  Registra?on  is  the  process  to  create  a  template  of  the  finger  prints  are  scanned  in  the  device.  The  same  finger  will  be  scanned   four  ?mes.  FlexCode  SDK  will  generate  a  unique  template  for  the  finger.  FlexCode  SDK  comes  with  a  special  algorithm  to  reduce  the  error   when  the  registra?on  process  is  done,  for  example,  scanned  images  are  not  clear  enough  fingers  or  finger  posi?ons  different  in  the  four
!
fingerprint  image  capture.  Within  certain  limits  FlexCode  SDK  can  s?ll  produce  a  good  and  accurate  template  of  the  registra?on  process   was  not  perfect.
Following  command  to  register  a  finger  :
Dim WithEvents FPReg as FlexCodeSDK.FinFPReg
Set FPReg = New FlexCodeSDK.FinFPReg
FPReg.PictureSamplePath = "C:\FPTemp.BMP"
FPReg.PictureSampleHeight = 2050
FPReg.PictureSampleWidth = 1600
!
Use   PictureSamplePath ,   PictureSampleHeight  and   PictureSampleWidth  only  if  needed  to  display  the  scanned  image  to  view  the  applica?on.
Ager  the  declara?on,  do  command  to  fill  the  ac?va?on  code  so  that  the  device  can  be  used  in  FlexCode  SDK.  This  ac?va?on  is  unique,
!
meaning  that  each  device  has  a  different  ac?va?on  code  with  other  devices.
FPReg.DeviceInfo device_serial_number, verification_code, activation_code
To  start  the  registra?on  process  do  the  following  command  :
FPReg.FPRegistrationStart "MySecretKey"
!
For  secure  templates  are  created,  the  template  is  encrypted  by  using  a  key  word  that  can  be  defined  by  yourself.  The  same  keywords  will   be  used  when  the  process  of  verifica?on.
The  next  step,  a  same  finger  should  be  scanned  four  ?mes.  Ideally  fourth  scanned  images  must  be  clear  with  the  same  rela?ve  posi?on.  In   some  cases  it  may  be  FlexCode  SDK  will  ask  several  repeated  scans  to  produce  a  becer  image,  so  it  takes  more  than  four  ?mes  in  the  finger
!
scanned  on  device.  FlexCode  SDK  inform  the  number  of  fingerprint  images  need  to  generate  a  template  through   FPSampleNeeded  event.  So   scan  your  finger  un?l   FPSampleNeeded    return  a  zero  value.
When  the  fingerprint  image  has  been  created,  FlexCode  SDK  will  generate   FPRegistrationImage  event.  Fingerprint  images  are  available  in   accordance   with   the   defined   path   in   PictureSamplePath .   If   necessary   fingerprint   images   for   documenta?on,   this   image   can   be   saved   by
!
changing  the  name  or  rename  the  file.  Because  the  fingerprint  template  instead  of  the  template  image  and  can  not  be  converted  into  an   image.  Please  add  the  command  lines  to  save  /  change  the  image  file  name.

!

Once  the  registra?on  process  is  completed  when  the  event  returns  a  value  of  zero  then   FPSampleNeeded,  So   FPRegistrationStatus  will
!
return   r_OK  value  and  templates  will  be  generated  in  the  event   FPRegistrationTemplate .  Furthermore,  the  template  can  be  saved  to  your   database  or  file  and  distributed  as  needed.
!
To  cancel  the  registra?on  process,  please  call   FPReg.FPRegistrationStop
command.
!
If  the  registra?on  process  fails,  for  example  because  the  device  has  not  been  plugged  into  the  USB  port,  wrong  ac?va?on  code.  Error  code   can  be  known  from   FPRegistrationStatus  event.
FlexCode   SDK   can   only   create   a   template   from   a   scanned   fingerprint   finger   directly   over   the   device.   FlexCode   SDK   can   not   be   used   to
!!
process  the  file  fingerprint  images  into  the  template.  Therefore,  even  though  you  have  a  file  fingerprint  images  can  then  be  used  to  create   a  template.  These  restric?ons  are  for  security  reasons.  Fingerprint  technology  was  created  to  ensure  that  you  there  ( you  are  you ).
FINGERPRINT  VERIFICATION
Verifica?on  is  the  process  of  comparing  between  the  scanned  finger  and  the  fingerprint  template.  Verifica?on  can  be  done  1  to  1,  which   means  one  finger  scan  compared  with  one  par?cular  template.  Verifica?on  can  also  be  done  1  to  N  or  more  suitable  called  iden?fica?on,
!
which  means  one  finger  scans  compared  to  some  of  the  template  so  that  it  can  be  determined  whether  there  is  a  template  that  matches   the  scanned  finger.  FlexCode  SDK  can  do  both  of  these  means  of  verifica?on.
Following  command  to  verify  the  finger  :
Dim WithEvents FPVer As FlexCodeSDK.FinFPVer
Set FPVer = New FlexCodeSDK.FinFPVer
FPVer.PictureSamplePath = "C:\FPTemp.BMP"
FPVer.PictureSampleHeight = 2050
FPVer.PictureSampleWidth = 1600
!
Use   PictureSamplePath ,   PictureSampleHeight  and   PictureSampleWidth  only  if  needed  to  display  the  scanned  image  to  view  the  applica?on.
FlexCode  SDK  can  handle  up  to  10.000  devices  ac?va?on  code.  Using  the  mul?  devices  in  one  computer  is  not  to  speed  up  the  verifica?on
!
process  because  only  one  device  that  can  actually  be  used  at  a  ?me.
FPVer.AddDeviceInfo(device_serial_number, verification_code, activation_code)
Next  is  the  load  fingerprint  templates  that  will  be  used  in  the  verifica?on  process  to  the  SDK.  Here  is  the  command  to  load  the  fingerprint   template,   FPVer.FPLoad (id, finger_index, finger_template, "MySecretKey")
This  command  can  be  called  repeatedly,  un?l  all  the  required  template  in  the  SDK.  FlexCode  can  handle  up  to  30000  templates  in  a  single   verifica?on.   The   more   the   number   of   templates   are   listed   in   the   verifica?on   process   it   takes   a   longer   ?me   to   be   able   to   recognise
!
fingerprints  scanned  on  device.  So  load  templates  as  needed.  Templates  are  already  loaded  in  the  SDK  can  be  used  for  next  verifica?on   process.
To  remove  a  template  from  the  template  list,  use  the  command   FPVer.FPUnload (id, finger_index) .  Use   FPVer.GetFPCount
command  to
!
determine  the  number  of  templates  that  have  been  registered.  To  redefine  or  eliminate  the  en?re  templates  from  the  SDK  \  memory,  use   the  command   FPVer.FPListClear
.
The  verifica?on  process  FlexCode  SDK  can  be  done  in  the  background,  meaning  that  remain  ac?ve  even  FlexCode  SDK  applica?on  running   in  non-­‐ac?ve  condi?on  for  example  applica?on  is  minimized.  This  command  requires  administrator  privileges  on  Windows  Vista,  7  and  8.  In
!
other  words,  you  have  to  run  the  applica?on  in  a  state   run  as  admin .  Give   true  value  in  order  to  arrange  FlexCode   WorkingInBackground
SDK  can  s?ll  be  used  even  if  the  applica?on  is  minimized,  otherwise  give  a   false  value.
Ager   the   templates   are   load   to   SDK,   then   the   verifica?on   process   can   begin.   To   begin   the   verifica?on   process   using   command
FPVer.FPVerificationStart
or   FPVer.FPVerificationStart id .   If   id   not   informed   the   SDK   will   verify   FlexCode   1   to   N,   otherwise   it   will
!
verify  1  to  1.  Upon  this  command,  FlexCode  SDK  in  a  state  wai?ng  for  a  finger  scanned  on  device.
When  a  finger  is  scanned,  the  FlexCode  SDK  will  inform  you  if  the  fingerprint  image  is  ready  to  be  displayed  through   FPVerificationImage   event.  If  there  is  a  template  that  matches  the  finger  are  scanned  ,  then   FPVerificationID  event  will  inform  the   id  and   finger_index  .  If  it   turns   out   there   is   more   than   one   template   that   matches   the   scanned   finger   FPVerificationID   the   event   will   be   called   repeatedly.   It   is   important  to  prevent  the  registra?on  of  the  same  or  similar  template  using  different   id  or   finger_index .  To  determine  whether  the  finger   is  recognise  or  not  it  is  successful  ager  the  process  is  completed,   FPVerificationStatus  event  return   v_OK  if  the  finger  is  recognise  and   there   is   only   one   template   matching   of   all   exis?ng   templates   in   the   SDK   ,   v_NotMatch   status   if   the   finger   is   not   recognise   ,   the   status   v_MultiplelMatch   if   there   is   more   than   one   template   that   matches   the   scanned   finger   and   other   statuses   in   the   event   of   failure   of
!
verifica?on  or  cancella?on  .
!!
The   SDK   is   ready   for   the   next   finger   scan   or   do   FPVerificationStop   command   calling   for   stop   verifica?on   process.   When   you   call
FPVerificationStop  command,  the  loaded  templates  is  s?ll  in  memory,  so  you  can  call   FPVerificationStar any?me.
TAKE  FINGERPRINT  IMAGE  ONLY
If  you  only  need  a  fingerprint  image,  without  requiring  registra?on  process  and  do  the  fingerprint  verifica?on.  Use  this  variable  declara?on   as  follows:
Dim WithEvents FPImage As FlexCodeSDK.FinFPImg
!
Set FPImage = New FlexCodeSDK.FinFPImg
FPImage.PictureSamplePath = "C:\FPTemp.BMP"
FPImage.PictureSampleHeight = 2050
FPImage.PictureSampleWidth = 1600

!
!
The  next  step,  input  the  ac?va?on  code  to  SDK.  FPImage.
DeviceInfo device_serial_number, verification_code, activation_code
To  start  a  scan  of  a  finger,  please  use  the   FPImageStart ,  then  the  fingers  can  be  scanned  over  the  device.  When  ready  fingerprint  image  is
!
displayed,  FlexCode  SDK  will  inform  through   FPImage  event,  please  stored  the  displayed  picture  accordance  with  the  purposes.  To  dismiss   the  process  of  shoo?ng,  calling   FPImage.FPImageStop
command.
!!
In  the  event  of  failure  to  capture  an  fingerprint  image,  SDK  will  inform  you  via   FPImageStatus  event.
!!
Do  not  run  the  registra?on,  verifica?on  or  fingerprint  image  class  together.  One  moment  only  one  class  is  allowed  to  use  the  device.
UPDATE  THE  NEW  VERSION  OF  FLEXCODE  SDK
1. Override  the  old  SDK  file  with  new  ones.  This  file  is  usually  located  in   C:\Windows\System32  for  Windows  32  bit  or   C:\Windows\SysWOW64   for  Windows  64  bit  or   C:\Program Files\FlexCodeSDK  or  in  the  folder  you  specified  during  installa?on.
2. Please   register   the   new   SDK   file   to   the   system   registry   of   Windows   by   using   the   command   RegSvr32.
Example  of  command   C:\RegSvr32 FlexCodeSDK.dll
or   C:\RegSvr32 C:\Program Files\FlexCodeSDK\FlexCodeSDK.dll
!!
3. Please  open  the  sample  code  or  your  project  then  replace  references  to  refer  to  the  new  SDK.
DISTRIBUTE  IN  YOUR  APPLICATION
The  easiest  way  to  distribute  FlexCode  SDK  with  your  applica?on  is  install  the  FlexCode  SDK  setup  file.  This  setup  file  help  you  install  the
SDK  and  the  driver  files  of  U.are.U  fingerprint  reader.  If  you  do  not  want  to  separate  your  applica?on  setup  file  into  2  files,  then  you  can
!!
use   packager   applica?ons   such   as   Inno   Setup   to   run   hidden   the   FlexCode   SDK   setup.   FlexCode   SDK   file   is   only   one   file,   that   is
FlexCodeSDK.dll  but  the  driver  of  U.are.U  fingerprint  reader  is  very  complex,  will  waste  a  lot  of  ?me  if  you  try  to  ?nker  with  the  setup  file.
USING  FLEXCODE  SDK  IN  DELPHI
For  use  in  Delphi,  please  install  the  addi?onal  components.  Before  installing,   make  sure  the  sample  VB6  (the  executable  file)  can  run  normally  to  sure  the
SDK  have  been  installed  properly.  Ager  that  do  the  following  steps:
1.
Run  the  Delphi,  go  to  menu  Component  \  Install  Component…
2.
Click   on   Into   new   package,   browse   the   path   file   component
FlexCodeSDK.pas   (1) ,   enter   a   name   in   Package   file   name,     example   C:\programfiles\Borland\Delphi7\Lib\dcluser.dpk
(2) .  Click  the  OK  bucon  when  done.
!!
!!
!
