USB e-İmza Girişi, masaüstünde kurulan e-imza uygulamalarının işini iPhone ve iPad'de yapar: CCID uyumlu bir USB kart okuyucu ve nitelikli elektronik imza kartınızla, e-imza ile giriş kabul eden kamu portallarına giriş yapar, UDF belgelerini imzalarsınız. NELER YAPABİLİRSİNİZ • Avukat portalına, merkezi kamu hizmet kapısına, ulusal elektronik tebligat sistemine ve kayıtlı elektronik posta (KEP) web postanıza kartınızla giriş. • Belge İmzala: UDF belgelerini seçip kartla imzalayın; sonuç yeni dosya olarak kaydedilir, kaynak dosyaya dokunulmaz. NASIL ÇALIŞIR Seçtiğiniz portalın kendi giriş sayfası uygulama içinde açılır. Sayfada görünen işlem kodu otomatik okunur; "İşlemi getir" ile imzalanacak metin gelir, PIN'inizi girip "İmzala"ya basarsınız. Girişi portal sayfası tamamlar. Uygulama sayfaya müdahale etmez ve yalnız sizin tetiklediğiniz istekleri gönderir. GİZLİLİK • Kart PIN'i yalnız karta gider; kaydedilmez, ağa gönderilmez. • Uygulamanın sunucusu yoktur; analitik, reklam veya takip yoktur. • Kimlik numaranız yalnız seçtiğiniz portalın kendi giriş servisine, o portalın gerektirdiği biçimde iletilir. GEREKENLER • Nitelikli e-imza kartı ve PIN'i • CCID uyumlu USB kart okuyucu veya USB e-imza tokeni • USB-C veya Lightning-USB adaptörü (güç girişli adaptör önerilir) • iOS 16.1 ve üzeri Bu uygulama bağımsız bir yazılımdır; herhangi bir kamu kurumuyla bağlantılı değildir ve bu kurumları temsil etmez. Portalların adları ve logoları mağaza sayfasında kullanılmamıştır; uygulama içinde yalnız hangi hizmete giriş yapıldığını belirtmek için portal adı gösterilir.

Verdict

The call

The clearest difference is in-app purchases: USB e at none against TIFF Viewer's 1. USB e also leads on ads (none vs shown) and update cadence (every 2 days vs every 10 days). On price, device support and iOS requirement there is nothing between them.
