VERIFACTU
Verifactu is the term that refers to the requirements that Information Billing Systems (Sistemas Informáticos de Facturación (SIF)) must meet, in our case, the Point of Sale Terminal (POS).
Verifactu's priority is to secure the keys in the company's or self-employed individual's billing records:
- Sequential recording of each system transaction and event (logs).
- Generation of a unique cryptographic digital fingerprint ('hash') for each record.
- Linking of records using the hash, creating a chain that prevents the deletion or insertion of invoices.
- Inclusion of a QR code on invoices, allowing for quick verification of basic data.
- Technical capacity to electronically submit records to the Spanish Tax Agency (AEAT).
How Verifactu Works.
The process of sending invoices with Verifactu is almost entirely automatic and is carried out through certified invoicing software adapted to Verifactu. It works as follows:
- Invoice generation: The invoice for the customer is created from the billing program (POS or management software).
- Automatic record creation: When the invoice is generated in the software, a billing record is created. This record is not the invoice itself, but a computer file (in XML format) with the essential data of the transaction.
- Signature and "Digital Fingerprint": The system applies a hash (digital fingerprint) to the record, linking it to the previous record, thus creating a 'blockchain' that guarantees the integrity and immutability of the data. No one can modify an issued invoice without breaking this chain.
- Submission to the Spanish Tax Agency (AEAT): The SIF or POS connects to the Tax Agency immediately, securely, and sends the record. The AEAT receives, validates, and stores it, also securely.
- Incorporation of a QR Code: The software generates a QR code and embeds it in the PDF of the final invoice or receipt issued by the POS.
- Sending the invoice to the customer. This QR code allows the customer (and the Spanish Tax Agency) to verify that the invoice has been declared correctly.
The Verifactu system is the technical basis of modern fiscal control and prepares the ground for the implementation of B2B (Business To Business) or inter-company electronic invoicing.

Digital Certification and Electronic Signatures
An electronic signature is a set of electronic data attached to a digital document (such as an invoice) that primarily serves two functions:
- Identifying the signatory: It unequivocally proves who issued or signed the document.
- Guaranteeing integrity: It ensures that the document's content has not been altered or modified in any way after signing. It acts as a kind of digital seal.
To create such a signature with full legal validity, an Electronic or Digital Certificate is required.
Key points for choosing a Point of Sale (POS) system
The myth of used POS systems.
In the world of Point of Sale (POS) terminals, it's increasingly common to find options with "pre-owned" CPUs at "seemingly attractive prices". However, what many businesses don't realize is that these solutions are often actually used equipment from leasing companies, heavily used and obsolete for any moderately demanding business environment.
In this article, we debunk the myth surrounding these worn-out and unreliable POS systems and explain why a new or refurbished modular POS system is the best option for your business, especially since at telespino.com you can optimize your financial resources in the short, medium, and long term and have the security of a Technical Support Service tailored to your needs.
