CrazyWriter HSP

CrazyWriter HSP

Turnkey OEM USB PC/SC contactless/RFID/NFC coupler solution

Like the other SpringCard USB coupling devices, the CrazyWriter HSP is in compliance with the PC/SC standard. The software integration and the application development are thus really easy. Moreover, the speed of the USB interface combined to the high rate of the ISO 14443 standard enable the  TwistyWriter HSP to reach the best transaction speed.

The CrazyWriter HSP is a modular product made up of:

  • a H663 module-based motherboard having a mini-SIM size SAM card slot (ID-000 / 2FF size)
  • a remote antenna linked by a thin micro-coax cable

Both cards measure 69x45mm (dimensions are shared by most of SpringCard OEM products) and are linked by a ribbon cable.

Two optional cards can complete the CrazyWriter HSP thanks to:

  • 1 contact card slot (ID-1 / 1FF size)
  • 3 additional mini-SIM sized SAM cards slots (ID-000 / 2FF size)

CrazyWriter-HSP: SC0168
3 SAM daughter board: SC0169
ID-1 slot expansion board: SC0170
