At the end of September, a change will take place in Slovakia that may appear purely technical at first glance, but could unexpectedly create practical problems for some foreigners. It concerns temporary and permanent residence cards, which many people view simply as documents confirming their right to reside in Slovakia. In reality, a foreign national’s electronic residence card can perform many additional functions. It can be used to access government electronic services, use an electronic mailbox on Slovensko.sk and, if the appropriate certificate is installed, sign documents with a qualified electronic signature.
On 25 August 2026, the Slovak Ministry of the Interior officially announced that the chip certification of certain electronic identity cards and foreign residence documents is expiring. This applies to documents containing a CardOS v5.4 chip that were issued by the Ministry between 21 June 2021 and 30 November 2022. According to the Ministry, approximately 130,000 holders of these documents currently have a qualified electronic signature certificate, known as KEP, installed on their cards. On 28 September 2026, these certificates will automatically expire on this type of chip.
The most important point for foreigners is to separate two different issues. The temporary or permanent residence card itself will not become invalid on 28 September. If your residence card, or pobytový preukaz, has not expired, it will remain valid and continue to confirm your legal status in Slovakia. Your temporary residence will not be cancelled, your permanent residence will not be terminated and you will not need to submit a new residence application solely because of this technical issue.
The change applies specifically to the ability to use the card to create a qualified electronic signature.
This is an important distinction. A person may live in Slovakia for years with a residence card and never use KEP. For that person, practically nothing will change after 28 September. However, if a foreigner conducts business, serves as a company director, communicates independently with government authorities through Slovensko.sk, submits electronic applications or regularly signs documents electronically, this issue becomes much more important.
KEP, or kvalifikovaný elektronický podpis, effectively serves as the electronic equivalent of a handwritten signature in the Slovak system. The official Slovensko.sk portal states that, under the European eIDAS Regulation, a qualified electronic signature has the same legal effect as a handwritten signature. In cases prescribed by law, if a qualified electronic timestamp is attached, this form of authorization may have the effect of an officially certified signature.
The issue is therefore much broader than simply being unable to log in to Slovensko.sk.
Cardholders will still be able to access many government electronic services if they have an activated BOK, or bezpečnostný osobný kód. The BOK is used for identification and logging in to electronic systems. However, accessing a system and legally signing a document are two completely different operations.
Here is a simple example. You may be able to open your electronic mailbox, read a message from a government authority or access a particular electronic service. In many cases, authorization with your card and BOK is sufficient for this. However, if you need to submit an application that must be legally signed, the system may require an electronic signature. This is where the absence of a valid KEP may become an obstacle.
This is particularly relevant for foreigners because Slovakia is gradually moving an increasing number of administrative procedures online. In addition, the Ministry of the Interior provides electronic services for foreigners that explicitly require an electronic residence card, an activated BOK and KEP. For example, in its official description of the electronic service for issuing a residence document, the Ministry states that an applicant must have an electronic residence document, an activated BOK and a qualified electronic signature. The electronic application itself must be confirmed using KEP.
For someone who actively uses government electronic services, this is therefore a practical issue, not a theoretical one.
There is another detail that may currently cause confusion. From 27 August 2026, the Ministry of the Interior allowed another certificate to be installed on the affected documents for what is known as an uznaný spôsob autorizácie, or recognized method of authorization. A new version of the eID Client software has already been released for this purpose. The state has therefore created a temporary way for people to continue using certain electronic services without immediately replacing their cards.
However, it would be a mistake to treat this as a complete replacement for KEP.
Uznaný spôsob autorizácie is an advanced electronic signature based on a qualified certificate. According to official information published on Slovensko.sk, it may be used only for certain electronic submissions and only where the relevant public authority accepts it. It primarily applies to the electronic application itself, while the requirements for electronic attachments and supporting documents may differ. If a particular procedure specifically requires KEP, the recognized method of authorization may not be sufficient.
Foreigners should therefore not assume: “A new certificate will be installed, so I do not need to change anything.”
You first need to understand how you actually use your residence card.
If you mainly use the card as proof of temporary or permanent residence, for travelling together with your passport and for ordinary identification, and you do not use an electronic signature, there is no urgent need to replace the document solely because of 28 September. Your residence status will not disappear.
However, if you use the card for KEP, electronic applications, communication with government authorities, business procedures or signing documents, it is better to check the situation in advance rather than waiting until 29 September, when you may suddenly need to submit an important application.
Foreigners whose residence cards were issued between 21 June 2021 and 30 November 2022 should pay particular attention. The Ministry of the Interior has identified this period as the timeframe in which documents containing the affected CardOS v5.4 chip were issued.
This is where another common misunderstanding arises. A person looks at the expiry date on the card and thinks: “My card is valid for several more years, so why should I replace it?” From the perspective of immigration status, that person is correct. From the perspective of the electronic signature, the situation is different. The physical document may remain valid, while the certificate stored on its electronic chip will no longer allow the holder to create KEP.
The Ministry of the Interior recommends obtaining a new document for anyone who requires a fully qualified electronic signature. Slovak citizens should contact a police department that issues identity cards. Foreigners should contact the relevant Foreign Police department to apply for a new residence document, or doklad o pobyte.
This raises a practical issue for foreigners. It is advisable not to postpone the decision until the final days of September. If many holders of affected cards decide to replace them at the same time, police departments may face increased demand, and appointments may become more difficult to obtain. This may be particularly noticeable in Bratislava and other cities with large foreign populations.
The recommended course of action is therefore straightforward. If your residence card was issued between June 2021 and November 2022, first check whether you use KEP and whether the relevant qualified certificate is installed on your card. If you do not use KEP and only need the card as proof of residence and the BOK to access electronic services, the date of 28 September does not mean that you must replace your card immediately.
If KEP is part of your work or your communication with government authorities, you should determine whether the new recognized method of authorization will be sufficient or whether your procedures require a fully qualified electronic signature. If KEP is specifically required, it is safer to arrange for a new residence document in advance.
Another important point is that BOK and KEP should not be confused. BOK is a code used for identification and access to government electronic services. KEP is a legally binding electronic signature. The statement “the card will continue to work” can therefore be both correct and misleading. The card may continue to work for logging in. However, after 28 September, it will no longer work for creating a qualified electronic signature if it contains the affected CardOS v5.4 chip and the old certificate.
For most foreigners, this is not a reason to panic and certainly does not affect the legality of their residence in Slovakia. However, for entrepreneurs, company directors and people who regularly handle matters through government electronic services, it creates an administrative risk that is better addressed in advance.
We recommend checking more than just the expiry date of your card. You should also verify its date of issue, how you use its electronic functions and whether KEP is installed. If you are unsure whether the change affects your card, whether it needs to be replaced or which electronic actions you will be able to perform after 28 September 2026, it is better to clarify the situation before you urgently need to submit or sign a document. The specialists at Slovakia Garant can review your situation, explain whether your card needs to be replaced and help you organize the next steps correctly.
