LinKad links a contactless smartcard or NFC tag to a person. Only an NFC-enabled smartphone is needed.

It accepts the optical character recognition (OCR) output of Google Goggles as personal particulars, thereby eliminating the need to key in the information. Nevertheless, input of personal particulars through the on-screen soft keyboard, or a physical USB/wireless/bluebooth keyboard still works. Otherwise, just click on a user file in Google Drive or Dropbox, and choose User Import to open it.

A user file is a simple text file. Each line of the file contains an IC number and a name, separated by a tab character.

After linking, the person taps the contactless card or NFC tag on the smartphone with the TapKad app running to indicate his or her presence. The presence may be used for attendance recording or even in a basic payment system. This eliminates the burden of remembering the names of your students and club members etc. They are represented by their cards or tags.

The apps that use the link data are :

- TapKad (records attendance)
- Attendance (creates attendance statistics)
- Notification (sends personalized SMS to attendees)
- Score Input, Result (record and publish examination scores, using RFID/NFC)
