Never reveal OTP!!!
Scammers are impersonating Touch N Go staff to scam victims by informing them that they will be offering free upgrade of their normal Touch N Go card to the RFID ones. In order to do so, the victim has to reveal the OTP send to their phone. Behind the scene, the scammers are basically changing the victim's TouchNGo ewallet ownership to their phone number.
The RFID Touch N Go cards cost only RM10 but as there is currently limited stock, a lot of scalpers are selling the card for RM50-RM80. Now scammers are homing in on this demand.
