nexID
It connects the physical product to a passport governed by model, batch or unit. The same foundation serves public experiences, enterprise operations and integrations without turning every scan into a claim the data cannot support.
About us · Digital Product Passport
We build the digital passport that stays with every product.
nexID is a Digital Product Passport (DPP) and traceability platform within the Inmovar Latam ecosystem. It organizes identity, declared data, documents, use, circularity and evidence in a record that evolves across the product lifecycle. NFC and QR are access points; permissions determine what each person or team can see.
NexID is a commercial brand operated by GUILLEN MARCELO ARIEL, the service's legal owner.
Inmovar Latam
It is the technology ecosystem that supports nexID's development and connects product, engineering and enterprise implementation.
nexID preserves the source, owner, date and status of each data point, and can verify digital events when evidence exists. It does not turn a brand declaration into a certified fact, does not by itself prove physical authenticity and does not automatically guarantee regulatory compliance.
What we build
A living record. Not a static page attached to a package.
The passport clearly separates what identifies the product, what each source declares, what can be viewed and what evidence supports a change.
01
Identity and scope
Reference, model, batch or unit. Granularity is defined by the product and the data that must be maintained.
02
Declared traceability
Origin, materials, manufacturing, supply chain and documents, retaining the source and owner of each field.
03
Use and circularity
Instructions, care, repair, reuse, separation and end-of-life guidance when that information is available.
04
Evidence and change
Version, date, source and verifiable events. Missing or unvalidated information is shown with its real status.
Information by role
One identity. The right view for each actor.
Not everyone needs —or should— see the same information. nexID applies permissions and context without duplicating the passport.
Person using or buyingWhat is it, how do I use it and what happens at end of life?
They see only published information and services available for that product, without exposure to internal operating data.
Brand and operationsWhat data is missing, who maintains it and which version is current?
They manage models, batches, units, owners, documents and permissions from a governed source.
Service and circularityHow can it be cared for, repaired, reused, separated or recovered?
They access specific instructions and actions when the brand publishes them and the role is authorized.
Auditors and authoritiesWhere did the data come from and what evidence exists?
They review source, status, date and history within the authorized scope. Access does not imply approval or certification.
How we make it operational
From scattered data to a governed passport.
We design the data and its responsibilities first; then we choose the physical carrier and the experiences that use it.
Model the passport
We define granularity, fields, source, owner, visibility and the update lifecycle.
Connect the product
We choose QR, standard NFC or secure NFC for the use case. The carrier opens the passport; it cannot replace data quality.
Govern the lifecycle
We version information, permissions and evidence so each actor sees what is appropriate at each stage.
