Relay felica exchange.
Two RC-S380
Python >=3.6 (just for f-string)
nfcpy
Connect both RC-S380 to your computer, then replace driver to WinUSB with Zadig (on Windows).
Place a card to either Reader.
Executing python relay.py makes the other reader an emulator.
It can replace exchange.
For example, To replace UNENCRYPTED decimal data 1000 to 12345
python relay.py -d 1000 12345
It is as same as
python relay.py -r e803 3930
in hex mode.
Also, it supports string replace.
python relay.py -e ABC XYZ
Long timeout (e.g. -t 1) often stabilize the exchange.
You should specify system code (-s) depends on the Reader.
Also, --ignore-polling option sometimes works.
--block-write-response option makes transaction inconsistent.
Be careful with use.
