Introduces support for EMV, DESFire, NTAG brute-force, NDEF URI generation, FDX-B, Indala, and T5577 brute-force in firmware and CLI. Adds new source files for RFID protocols and utilities, updates Makefile to include new modules, and extends command definitions and CLI units to expose these features. This enhances the device's capability to scan, attack, and interact with a wider range of RFID tags.

(Nah, for real; i tried my best, but is hard af to obtain an answer from android google walllet thing.... idk how BRUCE OS manages to even get the cards issuer)

It just prompts the phone for finger print unlock thing.... and time's out

*dont add tis crap ;( (still)

From a quick glance, nothing jumps out at me, but please remove the build_dev.ps1 as that doesnt fit in with the existing build system and we already have various ways to build on various platforms.

Waiting for someone more familiar with firmware to review.

Havent gotten it to work, on the desfire/emv stuff but there are a few changes which I think should be done initially, experiments have shown that EMV works much better with WTX

This includes the .c files but misses the header files, could be fixed by including the directory or the files one by one, would fix compilation issues

g_pcb_block_num ^= 1;

if ((buffer[0] & 0xC0) != 0x00) {
// Simple implementation: ignore chaining/WTX for now

WTX should make reading much more reliable, especially on non card emv or newer more secure cards.
