We previously reported that Wales NHS Covid passes become compulsory on 11/10/2021. The Welsh Covid pass is compulsory for over-18s, and show people have either tested negative on a lateral flow test or are fully vaccinated against Covid to attend, for example, nightclubs.
The Welsh government has confirmed it will be an offence to fake a test result or use a counterfeit pass. The fixed penalty notice can be reduced to £30 if paid within 14 days. However, if it is not a first offence then the fine will double.
Alison Farrar, lead officer for Trading Standards Wales, told BBC Radio Wales Breakfast: "Scammers are so quick these days at getting onto anything that sounds legitimate.
"Because this is so new, no-one knows what the real thing looks like and therefore, if you do get a text or an email of some kind of communication saying this is how you do it, most of us aren't going to be able to tell the difference between the scam and the real thing."
Ms Farrar said people had already been scammed into paying for a pass after receiving a text or email from a scammer.
"The warning signs are when they look like they're going to start asking you for your card details, even if they claim they're not going to take any money. Why would they need your banking details otherwise?"
She urged people to "think it through properly" before clicking links and responding to "urgent" requests received from unknown senders.
