Visa karttan çıkardığım çipi nasıl NFC tagı olarak kullanırım?

MrEnessHS · 6 Mayıs 2023

Elimde kullanmadığım temassız özellikli bir Visa kart vardı. Boş boş duracağına içindeki çipi çıkartıp kullanırım diye düşündüm. NFC teknolojisi hakkında pek bir bilgim olmadığı için direkt hallederim diye düşündüm ama pek öyle olmadı. Elimdeki çip aslında güvenlik sorunları yüzünden pek de kullanılmayan Mifare Classic 1k'ymiş. Kartı tarattığımda ekteki ekran görüntülerinde de göründüğü gibi Writeable olduğunu ve herhangi bir korumaya sahip olmadığını, mükemmel bir banka, gördüm. NFC Tools ve başka birçok uygulamada komutla veya direkt uygulamanın kendisiyle veri yazmaya ve sıfırlamaya çalıştım ama hep "I/O error" "NAK" "6E:00" gibi hatalar ile karşılaştım. "6E:00" yanlış bir olaya, adının ne olduğunu tam bilmiyorum NfcA IsoDep vs, veri gönderdiğimi belirtiyormuş. ISO14443-A ile komut gönderdiğimde ise NAK diye bir hatayla karşılaşıyorum. Nasıl kartı sıfırlayıp kendi verilerimi yazabilirim? Ekte birkaç farklı uygulamadan aldığım kart verileri mevcuttur. Şimdiden teşekkürler, iyi forumlar.
