E-signature, being a tool used for the verification and signing of digital documents, can be applied in various contexts, including financial transactions. However, since some banks may still prefer traditional physical signatures or mobile applications for certain processes, it is important to consider the following aspects when using E-signatures:

1. Kredit Applications and E-signature: Many banks have started accepting documents signed with E-signatures as part of their customer strategies and methods for processing credit applications. This means that you can use E-signatures for your credit applications. However, the security of your E-signature is crucial.

2. E-signature Security: Never share your E-signature with others. It is essential to regularly change your password, and most importantly, report the loss or theft of your E-signature device immediately to deactivate it. This is vital to ensure the security of your E-signature.

3. Bank Preferences: Some banks may still prefer traditional physical signatures or mobile applications for processing transactions. However, with the increasing adoption of E-signatures, this may change in the future. Therefore, as users of E-signatures, it is essential to take security measures and understand the advantages and responsibilities that come with E-signature usage.

4. Usage Permission and Responsibility: Do not grant permission for others to use your E-signature under any circumstances, and prevent unauthorized usage. In mandatory situations, ensure proper monitoring of your E-signature. Remember that the entire responsibility of E-signature usage lies with you.

E-signature is a powerful tool that allows secure and efficient digital transactions. However, it is equally important to bear the responsibility that comes with this power. Therefore, it is crucial to be cautious about E-signature security and correct usage.
