Contactless transaction using gnuradio?

hello,
i am interested in learning if it is possible to use gnuradio to
implement
a similar application to how tagpay works, here are some details

Norman,

From a signal processing standpoint, sure, GNU Radio should work with
the basic idea. The issue you face is how to get the information into
and out of GNU Radio to the external world. You might be able to use
the audio I/O, but my guess is that you’ll need some more specialized
equipment. Of course, I say this after a 1 minute look at that
website, so I’m sure there are subtleties that I’m missing.

but was interested to see working examples of how to work with the data once
it has been received, for example, if i have a python script which creates a
dictionary or a key:value object this then generates a unique signal then to
be able to process this signal and read the key:value object.

Well, we’re really just interested in getting data in and out of a
communication application. Once you have the data, it’s a bit outside
of our box. You might find some useful applications over at cgran.org
that use GNU Radio with other data sources/sinks for inspiration.

is my understanding correct of the process and are there any security issues
with this?

thanks

And yes, I’m sure there are security issues. Aren’t there always :slight_smile:
