Hardware

Option 1: NARD flipper add-on

Buy it assembled at Red Team Tools, with or without SAM.

Or build it yourself from the files in the NARD repo.

Optionally 3d print a case designed by Antiklesys.

Option 2: Smart Card 2 Click

Put SAM (USA EU CA) into adapter (because of chip on top) and plug into reader (alt: digikey with cheaper US shipping). Connect reader to Flipper Zero (See Connections below).

Optionally 3d print a case designed by sean
