A coding mistake by the Certification Center, the company behind the software of ID cards, means 250,000 ID cards could cause problems for users in the future.
The problem concerns Estonian ID cards issued between September 2014 and September 2015, and if not fixed, will mean users are unable to use ID cards with the new version of the Google Chrome browser, the world's most popular browser, the Estonian Cyber Security News Aggregator reported.
“We let a fault slip through our software development process,” Certification Center head Kalev Pihl told Postimees, adding that the card can currently be used with Google Chrome.
The problem surfaced when Google worked out a new version of Chrome, which has more detailed checks, with Pihl saying their mistake was found out in beta testing of the new browser.
Pihl said they have secured a six months transitional period from Google, which will allow Estonian ID card users to carry on using the browser, adding that this should be enough time to fix the problem on Estonia's end.
