#235 RFID Hacking and Cloning with Magic Cards, Proxmark3 and Arduino (T5577) - YouTube

3 types of RFID cards:

125kHz/134kHz Low Frequency (LF) ... najčešće okrugla antena
13.56Mhz High Frequency (HF) ... najčešće pravokutna oko ruba
Ultra High Frequency (UHF)

125kHz starije, uglavnom samo ID

chinese magic cards – cards with changable ID

proxmark3 – for analysing and hacking

pn532 vs rc522 differences:

pn532 bolji range
rc522 bolji library
