Soft-Block vs Permanent Block (Kisme Kya Hota Hai?)

Agar aapne ATM ya swipe machine par 3 baar galat PIN enter kiya hai, toh card 24 ghante ke liye "Soft-Block" ho jata hai[cite: 10]. Is case mein card 24 ghante baad apne aap chalu ho jata hai, ya aap NetBanking se naya PIN set kar sakte hain[cite: 10].

Lekin agar aapka card kho gaya hai aur aapne customer care ya app se "Hotlist / Permanent Block" kiya hai, toh use dobara unblock nahi kiya ja sakta[cite: 10]. Is case mein bank naya debit card issue karta hai[cite: 10].
