PROBLEM DESCRIPTION

I would like to integrate the gwiot 7941e module and continue to use scanned RFID codes.
I used the search function. However, nothing found that helps me.

There is a very small and nice a cheep rfid reader available with intergrated antena avaiable on the marked.

The RFID reader is using UART
There is a Arduino library avaiable on github
https://github.com/gutierrezps/gwiot7941e?tab=readme-ov-file
A arduino reference is avaiable here:
https://www.arduino.cc/reference/en/libraries/gwiot-7941e/

It would be nice if Tasmota was able to support this device and read the RFID.

That will not help connecting reader to Tasmota. What is your application (what are you trying to do) ?

Tasmota supports D0 /D1 connection to GPIO if you build it with the Wiegand option.
define USE_WIEGAND // Add support for 24/26/32/34 bit RFID Wiegand interface (D0/D1) (+1k7 code)

It can then display the serial number of the card, that is all. If you want more features you are better off looking at something like - https://github.com/esprfid/esp-rfid.

In any case better if you open a new discussion rather than going off topic here.

Okay. So the reason why I'm doing this is that since Bitcoin is getting big, there's no real way to process it so I want to see if I can make a credit card that can store Bitcoin and use it as a payment method so you could have Bitcoin on it and then there'll be. A Bitcoin reader, and then you just tap it like how you're tapping a regular bank card. Because if bitcoin's going the way it's going, we're going to need some sort of way of transferring and using bitcoin

OK so that's well and truly out of scope for Tasmota then. You would need to look elsewhere I'm afraid.
Tip you need to do some research on reading and writing to smart cards encryption etc etc ... good luck with your project.
