Real-Time Water Meter Recognition System for Edge Devices: OCR Studio’s Paper Published in the SPIE proceedings of ICMV 2025
Last year, OCR Studio made its debut at the 18th International Conference on Machine Vision (ICMV 2025) in Paris, France.
Brazil stands out as an innovation overperformer in Latin America, maintaining this position for five consecutive years. This strong innovation environment is driving demand for digital technologies. Brazil’s identity system is undergoing a major transition from state-issued RG cards to the national CIN, creating new requirements for ID scanning technologies. This makes a reliable ID OCR and a flexible ID scanner essential for digital onboarding, KYC, financial services, and public-sector applications.
In today’s blog post, we explore Brazil’s changing identity document landscape and the key technologies required for accurate ID scanning.
Brazil is moving from a decentralized identity-card model to a national standard. The Carteira de Identidade Nacional (CIN) replaces the old Registro Geral (RG) model as the country’s standardized identity document, with the CPF serving as its single identification number.
Historically, different states could issue their own RG cards, so the same person could have a different RG number in each state. The CIN is designed to standardize civil identification across Brazil.
For businesses, this creates a transitional ID-scanning environment. New CINs coexist with legacy RGs, which remain valid until February 28, 2032. The CIN itself is available in several formats: paper by default, a polycarbonate card for an additional fee, and a digital version.
Depending on the use case, Brazilian ID card scanner may need to accommodate:
This makes broad document coverage and flexible ID OCR essential for the Brazilian market. An effective ID scanner must be able to work across the country’s transitional document landscape, supporting both legacy RGs and the new CIN alongside other Brazilian-issued IDs.
Brazil’s highly digital financial and public-service infrastructure creates many points for ID scanning. Brazilian ID scanning tasks may appear in:
Brazilian Data Protection Law (LGPD) adds another practical consideration: organizations handling personal information need appropriate safeguards, which makes local deployment the best option for businesses that want tighter control over identity data.
The technical challenge is therefore not simply supporting Portuguese text, which is used in Brazilian IDs. A capable ID OCR solution needs to understand where relevant fields are located across different document designs and extract them consistently. It should also be resilient to real-world capture conditions: crop document images, blur, reflections, low light, and camera movement.
That makes the following capabilities particularly relevant:
| ID scanning capability | Why it matters for Brazilian documents |
| MRZ scanning | Both the CIN and Brazilian passport include an MRZ based on international standards |
| Multiple document layouts | CINs coexist with legacy RGs, while CNHs, passports, and CRNMs add further document layouts |
| RFID chip reading | Brazilian passports contain a contactless chip that can be read using the NFC technology |
| Challenging image capture | Paper CINs can be more prone to wear, while polycarbonate ID cards can produce glare when captured |
OCR Studio’s solution is a strong fit for Brazil’s ID scanning landscape. Its client-side ID scanner extracts identity data locally, without sending document images to external servers. It is designed to address document diversity and difficult capture conditions that Brazilian ID scanning can involve.
For digital services, Web-Native OCR enables document capture directly in the browser on both desktop and mobile devices. You can test Brazil ID scanning through OCR Studio’s Web Demo with no installation required.
OCR Studio solution supports:
For businesses working with Brazilian identity documents, that combination addresses the actual market needs – from multiple ID templates support to privacy-first ID scanning, without moving sensitive identity data to an external infrastructure.

1. Why is automated ID scanning important for Brazil’s digital economy?
Automated ID scanning helps financial institutions, government services, and other digital platforms speed up identity verification, remote onboarding, KYC, and customer data extraction. It also reduces manual data entry and helps businesses process large volumes of Brazilian identity documents more consistently.
2. Which Brazilian identity documents OCR Studio ID scanner supports?
OCR Studio ID scanner supports the CINs, and legacy RGs to cover Brazil’s transitional document landscape. It also supports passports, driver’s licenses, medical cards, military ID cards, and many other identity documents.
3. What challenges must Brazilian ID OCR handle?
Brazilian ID OCR must recognize multiple document layouts and reliably extract data despite glare, low light, faded printing, bent pages, camera movement, and imperfect framing. Reliable recognition across these conditions is especially important for remote onboarding, where users capture documents with different smartphones and cameras.
4. What technologies are needed for effective ID scanning in Brazil?
Effective ID scanning combines MRZ, barcode, and VIZ reading, as well as RFID chip data extraction. Support for multiple document formats helps businesses automate ID scanning across CINs, CNHs, passports, and other Brazilian IDs.
5. Why is client-side ID scanning beneficial for businesses?
Client-side ID scanning enables ID data extraction directly on the device or in the browser instead of sending document images to external servers. This is particularly relevant for digital onboarding, KYC, and services handling personal data under Brazil’s LGPD. It also gives organizations greater control over customers’ sensitive identity data and reduces unnecessary data transfers.
