Employee agreements usually include sensitive information such as personal numbers and salary information. When adding SMS to your process, you will add another layer of protection to the contract, and combined with an eID increase the level of security and ensure that only authorized personnel can access the document.
Scrive recommends using SMS PIN in combination with an eID, for example, BankID. The SMS process will allow you to view the document and then sign with the eID verification.
Using SMS is not only relevant to HR contracts but all contracts containing sensitive and personal data.
