What is NFC Reader?

ZOLOZ NFC Reader uses the NFC function of mobile devices to decode ID document chips and read their encrypted information, enabling fast and accurate ID data extraction.

NFC Reader is applicable to remote identity authentication, automatic data entry, and similar scenarios. It improves data processing efficiency, reduces manpower costs, and prevents fraudulent attacks such as forged ID images, enhancing business security and risk control.

Features

Document verification

Verifies whether a document chip is readable, improving anti-spoofing detection capabilities.

Document readability

Reads ID information stored on the chip quickly and accurately.

Record query

Query NFC Reader results in the ZOLOZ Portal to review verification outcomes during business operations.

Supported document types

ZOLOZ NFC Reader supports the following document types:

• Standard passports with NFC chips

• China mainland residents' permit for traveling to-and-fro Hong Kong and Macau

Accessibility modes

NFC Reader supports native App SDK integration with both Native SDK and server-side API. For the detailed integration process, see Native App SDK access mode.

Use flow

The following figure shows the NFC Reader workflow:

1. Pass in key fields

   NFC chip information reading relies on three key mandatory fields: ID number, date of birth and expiration date, which customers need to pass in in advance.

   The following methods are supported:

   • If the customer has already stored these key fields locally, call the ZOLOZ NFC Reader initialize API to pass them in directly.

   • If the customer has not stored these key fields before: please call the ZOLOZ NFC Reader initialize API and scan the ID through the local SDK OCR. The SDK will automatically scan the ID image and detect the three default fields.

2. Read ID information

   Place ID card chip against the NFC area on the back of the mobile device for reading. Keep the ID card stable during the reading process until the page shows that the reading has completed successfully.

3. NFC Reader result

   Obtain the ID information reading result through the checkresult interface.

Use limitations

• The mobile device must support NFC and have NFC enabled.

• Android and iOS systems must meet the minimum version requirements.

Advantages

Flexible services

NFC reading requires three mandatory fields: ID number, date of birth, and expiration date. You can store these fields locally and pass them through the ZOLOZ NFC Reader initialize API, or scan them directly by using the SDK OCR.

Accurate readings

Once the NFC area is identified, readings complete quickly with accurate results, as external environmental factors have minimal impact on the process.

High security

NFC chip-based information reading provides stronger security authentication than traditional document image recognition.

Simple and easy-to-use

NFC Reader provides detailed integration documentation, operational backend support, and standardized API interfaces and SDKs for easy integration.

Common scenarios

Remote identity authentication

In finance, insurance, life services, healthcare, education, transportation, and other industries, NFC Reader provides document capture and detection capabilities for online account opening and registration. It automatically recognizes document information, improving data processing efficiency and reducing fraud risk.

Automatic data entry

In the medical, financial, government, legal, and education industries, NFC Reader enables fast identification and card data entry, reducing labor costs and improving information processing efficiency.
