The staff could create an account during a phone/mail reservation...

"At this moment, for privacy reason, only the user can register themselves, the staffs can not do that."

The legislation on personal data makes it possible to register a customer who reserves by phone or by mail or by email! Why not put a checkbox that would register the BO client from the direct telephone reservation?

The GDPR law makes it clear that an informed agreement is required; if you ask people for permission to create an account on the site so as not to have to enter new contact details and receive newsletters and that he can, if he wishes, unsubscribe from newsletters or revoke his consent, and delete his account, then YES the law allows it.

Here is proof that verbal consent is legal! Otherwise, how can you make a telephone reservation !? France is the leading tourist country in the world! And the law does not prohibit taking addresses and names, or the VAT number, but the law prohibits using it for commercial prospecting or resale of contact details. It also requires you to be able to delete or modify your personal data, which is the case with Joomla! and an extension of the GDPR JExtension.
In addition, all competitors Solidres have the possibility in their PMS to record and do a research on your customers, except it!
In France we have the CNIL, the Data Protection Act, and all of this exists long before European law and the GDPR! French law goes far beyond the GDPR law!
The French text of law: www.cnil.fr/fr/reglement-europeen-protec...s/chapitre2#Article7
The detailed explanation of the CNIL about consent (in French) : www.cnil.fr/fr/conformite-rgpd-comment-r...tement-des-personnes

Please make sure that we can create a Solidres account by checking a box in the BO! Otherwise your quick search no longer makes sense!

Thank you
