Requirements

Two RC-S380

Python >=3.6 (just for f-string)

nfcpy

How to use

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.

Replace

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

Tips

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.
