Nuremberg, Germany (dpa) – Hundreds of fake QR codes for Germany’s digital Covid-19 vaccination certificate were allegedly produced by a pharmacy employee and an accomplice and sold online.

Officials searched a pharmacy in Munich and several residences on Friday. A woman and another suspect were remanded in custody, investigators for the Bavarian Central Office for Combating Fraud and Corruption in the Health Care System (ZKG) said on Saturday.

The fake codes are said to have been on sale on a German-language cybercrime online forum since mid-August. Recently, buyers could purchase a digital vaccination certificate – without having been vaccinated against the coronavirus – for 350 euros (407 dollars).

In October alone, the forgers allegedly issued more than 500 vaccination certificates.

Officials seized almost 100,000 euros (116,440 dollars) in cash and cryptocurrencies during the searches. One fake vaccination certificate was found in another EU country, they said. However, many are likely to be circulating in Germany.

It is not possible to determine the names of the buyers, according to officials. It was initially unclear whether the fake vaccination cards could be deleted or otherwise rendered invalid.

The forgers are said to have used the Munich pharmacy’s IT infrastructure. The pharmacist himself is not suspected of involvement, the investigators said.
