I'm a UX Architect based in London working on a site for our office in Singapore that provides insurance products to customers. It has been suggested that we use a customer's NRIC as their username to log in to their account. I'm not sure if this is a common use of the NRIC in Singapore or if this would be unusual. I have been told that everyone knows their NRIC in Singapore, but that doesn't really answer my question.
The UK equivalent would be to use your NI number as a login, which is not something that we would do here.
If anyone either from or based in Singapore could let me know if it is standard to use your NRIC as a login username, that would be hugely helpful. Thank you.
