THIS APPLICATION IS ONLY FOR TESTING AND EXAMPLE PURPOSE, FOR MORE ROBUST CONTROL OVER NFC READER GO TO [http://github.com/jorgegarrido/arygon_nfc]
======= ehecatl ≈ ≈ ≈ ≈ ≈ =========
Ehecatl is the wind god in aztec mythology but also is:
An erlang driver for read/write nfc smart cards.
======= notes ==========
ehecatl
was tested using nfc smart cards with block size of 4 bytes (8 bits)
was tested using arygon nfc reader (Arygon NFC/MIFARE Plug & Play Module RS232)
was tested using pcsc lite under CentOS
======= how to use ===========
clone the ehecatl project from github:
$ git clone https://github.com/jorgegarrido/ehecatl.git
move into ehecatl directory:
$ cd ehecatl
compile ehecatl:
$ make all
(maybe warnings appear when compile, and a lib/libehecatl.so must be created)
start ehecatl:
$ make ehecatl
(an erlang shell must be opened)
========= starting, reading and writing on nfc smart card ============
in erlang shell:
starts the port driver ehecatl:
> ehecatl:start().
<0.??.0>
now, you must set a smart card near of nfc reader, when you are ready, then:
reading the smart card with ehecatl:
> ehecatl:flush(read).
%% here the reponse
the response will be a string in erlang, but if the block 08 is not writing yet, then the response will be 0
writing the smart card with ehecatl:
> ehecatl:flush(write).
ok
it must write the string "hola" in the block 08 in the smart card, now if you try read again, you will see "hola" as response of read command
==== reading smart cards when is inserted on nfc reader (automatically) ========
First open an erlang shell with the correct path:
$ make ehecatl
In erlang shell:
starts the ehecatl application:
> application:start(ehecatl).
ok
now just swipe a card into nfc reader and you will see:
> shell got <<"????">>
where ???? refers to data written in the smart card
