Why are registered names displayed instead of nicknames when making PayNow transfers?

To enhance security and protect the community against impersonation scams, the Association of Banks in Singapore (ABS) has discontinued the use of customisable nicknames for retail users. By displaying a version of the recipient’s actual bank-registered name (with privacy masking), GXS helps you ensure you are sending money to the intended person rather than a scammer using a fake nickname.

If you need more info, you can find the full details over on the ABS website.
