Security QR Codes (SQRC)

SQRC (Security QR Code) is developed from the QR code and is meant to prevent unauthorised access to the personal and private data captured of users. With the Security QR Code, only authorised users with the correct encryption key can access the hidden data.


Healthcare Industry

Prevent disclosure of patient’s personal information:
  • Hide National Registration Identity Card numbers, residential address, contact numbers, age etc
  • Only authorised users (Doctors abd Nurses) are issued with an encryption key to access the hidden information.
SQRC can be used on patients’ wristbands, specimen, medical records, visitors’ sticker pass, medicine prescription, blood bag and medication labels.

General Application Forms

When you are filling up an application form, do you feel unsafe when the mandatory fields are for your personal information? For example National Registration Identity Card numbers, credit card numbers etc.

In a company, not all information in a form is necessary to be revealed to staff of all levels in a company. Information that talks about changes in the company structure, profit and loss details, staff salary, etc. are needed to be revealed to staff who need to know.

With the SQRC, we can solve the above issue by hiding the “confidential” information and revealing the “public” information. The hidden information is safely locked within the QR code and available for access only by authorised personnel with the correct encryption key.

SQRC in Ticketing Sector


High security ticketing services can be implemented at your ticketing booth. Information on the date and time of purchase can be hidden in a QR code for verification purpose at the ticketing booth. However, the details of the user remains unknown as it is hidden in the QR code. Only personnel with the correct encryption key can access the hidden information.
