Electronic Signature

How to get started with digital signatures for car rental

A digital signature is a way to sign a car rental agreement in minutes, no matter where exactly you are. This way, you can book car rentals, issue invoices, and sign contracts anywhere and anytime. All you need is a smartphone or tablet and an electronic signature.

What Is a Digital Signature?

Digital signatures work the same exact way that handwritten signatures do. They are unique to each person. Digital signatures adhere to the standard format of PKI. PKI states that the document provider, in this case, Oneflow, uses an algorithm to create a number sequence which are called keys. One public and one private key is created during each digital signature. The private key is used to sign, while the public key is used to verify. 

Every time a person signs a document electronically, the signature is created using the signer’s private key. This is securely contained by the signer. During the signing process, the algorithm becomes the cipher with which it matches the data from the signer with the signed document, then encrypts it. The encrypted data is the digital signature. The signature is recorded with a date and time stamp for that document, and if any changes are made to the document after signing, the digital signature is no longer valid. 

Maintaining the integrity of the digital signature is vitally important. According to the terms set out by PKI, the keys must be created, conducted, and saved in a secure manner that requires a reliable Certificate Authority. Make sure your contract management software meets all the PKI requirements for safe and secure digital signatures.

A digital signature can be used for the following types of documents that are needed to rent a car:

  • Reservation
  • Rental agreement
  • Authorization
  • Opening of a deposit
  • Insurance

Electronic signature makes the whole process of renting a car extremely quick.

How to Set Up a Digital Signature for Car Rental

In order to properly set up a digital signature before signing a contract, car rental businesses employ dedicated IT solutions for this purpose. 

How to Sign a Car Rental Agreement with a Digital Signature

No matter which software you choose, the way of doing it is broadly the same:

  • The company manager sends you the document by email, and you receive a notification about it
  • Next, open the received PDF document or an online form
  • Put your digital signature
  • Confirm the insertion of the information with a checkmark, a special checkbox, or an image
  • Then, you receive another notification that confirms that the agreement has been transferred and confirmed

After that, many services allow you to get a copy of the document. It is worth remembering that a digital signature can be used only once and cannot be transferred to another document. This is what provides the authenticity of the agreement signed with it (such a document cannot be falsified).

The key takeaways

A digital signature is a convenient way to sign a car rental agreement without physically going to the office. You only need a personal computer, tablet, or smartphone for it.

A digital signature has properties of authenticity and irrevocability.  Depending on the level of security, a digital signature can be qualified or unqualified. The first type is used when you need the maximum level of legal security and protection against unauthorized access.

If you need to minimize risks, but do not need a high level of security, you can use a simple type or an unqualified type.
