# pn53x-sam(1)

PN53x SAM communication demonstration tool

## NAME

pn53x-sam - PN53x SAM communication demonstration tool

## SYNOPSIS

**pn53x-sam**

## DESCRIPTION

**pn53x-sam** is a utility attempt to test a simple connection with a SAM (Secure Access Module) in several modes.

To run this utility you must have a SAM (like the NXP's P5CN072 chip) successfully connected to your PN53x chip.

Warning: the SAM inside a Touchatag/ACR122U  is *not* hooked to the PN532 but to the intermediate controller so **pn53x-sam** won't work with a Touchatag/ACR122U.

## BUGS

Please report any bugs on the **libnfc** issue tracker at:\
