DataNZ provides top-notch indexing services to ensure high accuracy in data extraction and conversion. With our advanced Optical Character Recognition (OCR) process that utilises three separate OCR engines and digital comparison of their outputs, we achieve an indexing accuracy of over 99%. Additionally, our sophisticated data entry process using XML technologies guarantees efficient document search and retrieval.

We offer indexing services in multiple languages such as English, German, Dutch, French, Spanish, Italian, and the Nordic languages. Our services not only cover printed and handwritten information, scanned images, but also offline indexing and online data entry directly onto your servers.

Our guaranteed accuracy levels range from 99.90% for Single Key with 100% check to 99.999% for Blind Triple key / Triple Compare. For instance, our 99.999% accuracy level allows for no more than one error per 100,000 characters, which includes the inclusion or omission of a space, character, or punctuation. We also employ custom software tools to validate the indexed data fields, ensuring a high level of accuracy.

At DataNZ, we prioritise the security of your data, and we have put measures in place to protect it at all times. We handle a large volume of highly sensitive data, including financial and banking data. You can trust us to deliver exceptional indexing services while maintaining data security.
