Online shopping and registration: a common but not always correct practice
In today's e-commerce landscape, purchasing online has become a daily habit. However, behind a seemingly simple gesture like placing an order lies a delicate balance between commercial needs and personal data protection.
More and more platforms require you to create an account to access services or complete a purchase. This choice is often justified for organizational or marketing reasons, but it raises important regulatory questions.
The key issue is not whether recording is useful — because it is — but whether it can be set as a mandatory condition.
When registration becomes a problem
From the user's perspective, mandatory registration introduces an additional step that is not always necessary to complete the purchase.
This involves entering personal data even in situations where:
- the purchase is occasional
- there is no ongoing relationship
- no future user management is required
According to the indications of the’European Data Protection Board (EDPB), this type of practice is not neutral. On the contrary, it can directly impact users' rights and freedoms, especially when it involves data collection that is more extensive than necessary.
The problem is not only the amount of data collected, but also the overall impact of the treatment.
The risks associated with excessive data collection
Forcing a user to register means collecting and storing information that, in many cases, is not essential to the transaction.
This can generate several risks:
- unnecessary accumulation of personal data
- prolonged storage without real justification
- systematic tracking of user activities
- use of data for further purposes, such as profiling
Furthermore, in some cases, designs or interfaces are used that push the user to provide more information than necessary, making the process less transparent.
This approach deviates from the fundamental principle of the GDPR: collecting only the data strictly necessary.
The concept of “always identified user”
Another critical element concerns fully account-based systems, in which every user action requires identification.
In these contexts:
- the user cannot navigate freely
- every interaction is tracked
- the level of data exposure increases
This increasingly widespread model amplifies the risks associated with the processing of personal information.
It's not just a technical issue, but an issue that directly affects the relationship between platform and user.
What the GDPR says: the principle of necessity
The GDPR introduces a key principle: personal data must be processed only if necessary for the purpose.
In the case of online purchases, this means that to complete a transaction you only need:
- shipping data
- payment data
- essential information for order management
You do not need to create an account to collect this information.
For this reason, the EDPB emphasizes that, especially for occasional purchases, mandatory registration is not justified.
Legal bases: when is it legitimate to request an account?
The EDPB has analysed the main legal bases that could justify the registration requirement.
In the case of contract performance, the position is clear:
Creating an account is not necessary for a one-time sale.
The situation is different for ongoing services, such as subscriptions or platforms reserved for registered users. In these contexts, an account may only be required if it represents an essential part of the service.
As for legal obligation, registration can only be imposed if explicitly required by law. However, in most cases, laws only require the collection of certain data, not the creation of a profile.
Finally, legitimate interest cannot be used indiscriminately. It must respect the principle of data minimization, avoiding more invasive processing than necessary.
Guest checkout: the most consistent solution
In light of these principles, a clear solution emerges: offering the possibility of purchasing without registration.
The so-called guest checkout allows the user to complete the order by entering only the necessary data, without creating an account.
This mode:
- complies with GDPR
- reduces data collection
- improve user experience
- increase conversions
Registration can be proposed later, as an optional choice and not as an obligation.
Privacy by design: designing it right
The GDPR also introduces the principle of privacy by design and by default, which requires systems to be designed from the outset to protect data.
This means that:
- data collection must be limited
- settings must favor privacy
- less invasive alternatives must always be available
In this context, guest checkout is not just a technical choice, but a design solution consistent with regulations.
E-commerce strategy: less friction, more trust
In addition to the legal aspects, there is also a direct impact on performance.
A simpler purchasing process:
- reduces cart abandonment
- increases confidence
- improves brand perception
Forcing users to register can create friction and reduce conversions.
In digital, the most correct solution from a regulatory perspective is often also the most effective from a strategic perspective.
Conclusion
Mandatory registration in e-commerce is not just an operational choice, but a decision that involves regulations, user experience, and strategy.
The GDPR pushes for a more transparent and less invasive model, in which users retain control over their data.
Offering alternatives like guest checkout means striking a balance between business needs and consumer protection.
In digital, trust also arises from these choices.
