LINE API Use Case

CLOVA OCR (character recognition)

CLOVA OCR is a service that converts text and sentences written on forms and images into text data.

By using CLOVA OCR, the time required for inputting the information written on receipts and invoices, as well as the information on identification documents such as driver's licenses, into the internal system can be greatly reduced.

Even forms scanned under unfavorable conditions, such as handwritten or crooked characters, horizontal or vertical writing, or images that have not been photographed from the front, can be converted to text data with high accuracy.

*CLOVA OCR won first place in four fields at the International Conference on Document Analysis and Recognition (ICDAR: as of March 29, 2019).

Typical type
If the end user registers the layout in advance, the characters and sentences written at the registered positions can be converted into text data.

This type is effective for mass processing of standardized forms in the back office.

Atypical type
You can convert all the characters and sentences in scanned forms and images taken with your smartphone into text data. There's no need to worry about the orientation of the text or the layout of the document.

This type is useful for translating and tagging for search purposes.

It's also implemented in the LINE chat room.

Specialized type
The following layouts, such as driver's license (identification documents) and invoices, are already supported by CLOVA OCR, so there's no need for the end user to register the layout again.

  • Identification documents
  • Business cards
  • Receipts
  • Invoices

In the specialized type, not only can you convert to text data, but you can also classify the converted values into appropriate items. This classification is not done for "typical" and "atypical" types.

End-user benefits

LINE CLOVA OCR End-user benefits Smooth data entry

Smooth data entry

The time that used to be required for data entry, such as registering new members on a website, can be greatly reduced.

With CLOVA OCR, you can input data smoothly by simply uploading the image of your identification documents.

All image data of identification documents is processed on-memory and isn't stored on the server. After converting to text data, all data is immediately deleted. There's no need to worry about the data being leaked or analyzed.

Simplification of identity verification procedures

In the past, if you needed to verify your identity, you had to go to a certain place at a certain time or send documents by mail.

In cases where CLOVA OCR is used in combination with other technologies, such as eKYC (electronic Know Your Customer), the following identity verification procedures can be completed online.

  • Identity verification required when applying for government services at public institutions.
  • Identity verification required when opening a new account at a bank.

Service provider benefits

Promote smooth participation in the campaign

In the retail industry, such as food and beverage manufacturers, campaigns targeting receipts issued by POS registers are widely used.

In the past, you had to mail the receipts or email them as an attachment.

With CLOVA OCR, end users can participate in the campaign by simply sending receipts taken with their smartphones.

If you make it mandatory to add the LINE Official Account as a friend when sending a receipt, you can use your LINE Official Account as a communication channel with end users even after the campaign ends.

For example, you can use the LINE Official Account Manager or the Messaging API to send out continuous information (such as new product information) or marketing activities (such as sending coupons) to your end users.
