iOS Check Scanner Module

Scanning the MICR code on a paper check with the iOS Check Scanner

Overview​

Check scanning is a powerful feature designed to detect, read, and extract data from the Magnetic Ink Character Recognition (MICR) line on checks. This functionality allows your application to quickly and securely capture check details, including check numbers, dates, and other textual data fields.

By utilizing advanced text detection, check scanning ensures accurate data extraction even under varying conditions, such as different check orientations, lighting, or backgrounds. The extracted data is provided in a structured format, enabling seamless integration into banking systems, payment processing, and other applications requiring check details.

Check scanning simplifies the process, improves user experience, and enhances accuracy by reducing manual data entry. It is widely used in financial services, retail, and logistics, where fast, reliable, and secure check capture is essential.

The Scanbot SDK supports various checks formats:

  • USACheck: compatible with the ASC X9 standard used in the USA
  • FRACheck: format commonly used in France
  • KWTCheck: format commonly used in Kuwait
  • AUSCheck: compatible with the Australian Paper Clearing System check standard
  • INDCheck: compatible with the CTS-2010 standard issued by the Reserve Bank of India in 2012
  • ISRCheck: format commonly used in Israel
  • UAECheck: format commonly used in the United Arab Emirates
  • CANCheck: format commonly used in Canada

Integration​

There are two ways to integrate the UI components into your application:

warning

On iOS, processing very large images can lead to out-of-memory crashes!

Since this limit is highly dynamic and untransparent in iOS (depending on the device, your app's current memory usage, other apps running in the background, the iOS version, the system configuration, and many other factors), we did not add a hard limit for image sizes.

As a rule of thumb, it is safe to assume that processing images with resolutions that match the camera's resolution will not crash your app. On most modern iOS devices, this translates to 12 megapixels. But even much larger images may work without crashing.

Therefore, we cannot take responsibility for out-of-memory crashes when dealing with very high-resolution images. You as the developer need to properly manage the handling of large images and keep the memory footprint of your app as small as possible.

caution

Please do not use multiple scanners at the same time. For example, do not combine Document Data Extractor, Health Insurance Scanner, Text Pattern Scanner, etc. at the same time! Each scanner instance requires a lot of memory, GPU, and processor resources. Using multiple scanners will lead to performance issues for the entire application.
