title: programming custom functionality into Verifone or Ingenico - where to find SDK?
body: <p>I'm trying to get my hands on some low-end Verifone or Ingenico terminals for a custom e-voucher application. I found the devices at the right pricing and with the right functionality, but I'm quite dazzled because I can't find any information anywhere about how to program custom functionality into these things?!</p>
  
  <p>I hope I'm not into NASACIATOPSECRET land now? Or maybe we're supposed to purchase SDKs or whatnot?</p>
  
  <p>The farthest I got was some file listings on VeriFone's site that require login for download but I can't find any signup link.</p>
  
  <p>Would appreciate any pointers.</p>
