What is digital certification?

It’s a technology that ensures identification and authenticity of an individual, legal entity, application (system, network, software) or equipment in the digital environment.

What is identification by radiofrequency?

Known as RFID (“Radio Frequency Identification”), it’s an automated identification method that recovers and stores data remotely, using tags. These tags allow identification of the object to which they apply, since they contain information such as origin, destination, manufacture date, and others, according to the set out rules. The writing and reading of this information on tags are made by devices (writers/readers) through radiofrequency signals that Exchange data with computers systems.

Which technology is used to produce documents?

High security papers, plastic cards, PVC, polycarbonate and Teslin (synthetic paper). Printing is made in special laser equipment, engraving, Termotransfer for PVC, by impact and digital offset.

What are smart cards?

Smart Cards are cards that have as main feature and integrated chip attached to the card body, which has components for transmission, storing and processing of data. Data can be transmitted through electrical contacts placed on the card surface or through magnetic fields, for contactless cards.

Smart Cards are regulated by ISO/IEC 7816 ISO/IEC 14443. These standards jointly address contact and contactless transactions. Currently, EMVco is responsible for normalization, interoperability and acceptance of this type of transaction.

What is the biometric identification?

It’s an identification method that consists of collection, storing and analyzing biometric features, such as fingerprints, iris, faces, etc. of individuals, using reading devices (scanners, cameras, etc.) and sophisticated computational systems, ensuring authenticity. Biometric identification is used in simple systems, such as access control in turnstiles and high accuracy systems, such as criminal identification ones (AFIS = Advanced Fingerprint Identification System).

What does documents dematerialization means?

Turning physical documents (invoices and bank statements) into electronic documents.

How is the products traceability made?

Products traceability takes into account the need to know the origin, rout and position and/or destination of products, according to relevant business rules applied to them. In order to obtain this information, marking technologies are used (1D and 2D bar codes, RFID tags, QR Codes, Datamatrix, etc.) in products tracked, along with systems to read and analyze the information stored in this codes. In certain situations, it is possible to use technologies that, in addition to tracking, ensure full product authenticity, such as forensic markers that are incorporated to the product and can only be detected through laboratory analysis.

What is QRCODE?

QRCODE or Quick Response Code is a bidimensional bar code that can be used for quick identification of materials or information. It was designed due to the automobile industry need to label pieces and quickly identify them. Over time its use was extended to other applications, from inventory control and logistics, to mobile payment methods that use mobile phones cameras to capture transactions information. It can also be used associated to cryptograms and digital signature, in order to ensure secrecy and non-repudiation of information.

What is a digital signature?

It is an electronic signature, legally certified and used to validate any electronic file that has been signed using digital certification.

What is a SIM Card and what is it used for?

It’s a print circuit smart card type, used to identify, control and store data of GSM (Global System for Mobile Communications) technology mobile phone. It usually stores data such as member information, schedule, preferences (settings), services hired, texting and other information.
