Everything you need to prove who you are – digitally
CodeB Wallet keeps your documents on your phone, shows them in person or online when you decide, checks other people’s IDs and signs PDF documents.
Mobile driving licence
Keep a mobile driving licence (mDL) on your phone – as SD-JWT VC for online use and as ISO/IEC 18013-5 mdoc for showing it in person.
mDL · ISO/IEC 18013-5CodeB membership card
Add the CodeB membership card from the CodeB issuer and show it like any other document in your wallet.
AttestationAdd documents your way

Issuer list · QR codeShow your ID in person
Start with a QR code or an NFC tap; the data then goes phone-to-phone over Bluetooth Low Energy. Both BLE roles are supported for broad reader compatibility, and it works offline.
ISO/IEC 18013-5 · NFC · BLEShare only what is needed
Selective disclosure: confirm “over 18” without revealing your date of birth, or share just the details a service really needs.
Selective disclosureShare online
Websites and apps request data via OpenID4VP. You see every request – who is asking and for what – and confirm with your PIN or biometrics.
OpenID4VPVerify someone’s ID or age
CodeB Wallet works as an ISO/IEC 18013-5 reader with a clear verdict – trusted, look closer or do not accept – including a revocation status check. Nothing is stored.
ISO/IEC 18013-5 readerCheck an ID back to back

PAdES B-T · AdESHistory
A history of everything you added, shared and signed – with details – kept only on your phone.
On deviceSee who saw your document
Each document shows the recent times you shared it – who received it, when, and exactly which details. One tap opens the entry, where you can ask for deletion or report a verifier. Taken from the history on your phone; nothing is sent anywhere.
Transparency · GDPRAlways up to date
The wallet checks the status of your documents automatically and can renew them before they expire, where the issuer supports it.
Status · renewalReminded before a document expires
CodeB Wallet tells you on your phone when a document is about to expire or could not be renewed automatically – one tap opens it to renew. The reminder is created on your phone; nothing is sent anywhere.
Local · no trackingMade for everyone
Built with the European Accessibility Act in mind: works with the TalkBack screen reader, with very large text and with animations switched off – results, checks and steps are read out clearly, and card colours stay readable.
AccessibilityGuides and changelog
Built-in “Learn more” guides explain every function in plain words, and an in-app changelog shows what is new. Swipe through your cards on the home screen.
HelpHow it works
Four steps from issuer to verifier
The EUDI wallet model separates the issuer of a credential, you as the holder, and the service that checks it.
Get a document
Choose an issuer in the app – such as the CodeB issuer – or scan an issuer’s QR code. Issuance uses the OpenID4VCI protocol.
Keep it on your phone
The document is stored on your device. Its keys are protected by the phone’s secure hardware; the wallet is locked with PIN or biometrics.
Present it
Show it in person via QR code or NFC tap with data over Bluetooth Low Energy (ISO/IEC 18013-5), or online to a website or app via OpenID4VP.
You decide what to share
Before anything leaves your phone, you see who is asking and for what – and you confirm with your PIN or biometrics. Only the attributes you approve are shared.
Standards
Built on open European and international standards
CodeB Wallet follows the EU Architecture and Reference Framework (ARF) and is designed to comply with eIDAS 2.0. It is not certified and it is not an official government wallet.

Trusted issuers
Issuer trust is checked against EU trusted lists (ETSI) and your list of trusted issuer certificates.

FAQ
Frequently asked questions
What is CodeB Wallet?
CodeB Wallet is an Android app that stores digital documents – such as your Person Identification Data (PID), mobile driving licence or CodeB membership card – and presents them in person or online. It can also check other people’s IDs and sign PDF documents. It is built for the European Digital Identity (EUDI) framework under eIDAS 2.0, Regulation (EU) 2024/1183, by Aloaha Limited, Malta.
Who develops CodeB Wallet?
CodeB Wallet is developed by Aloaha Limited, a company based in Malta. Aloaha has been active in PKI, PDF development and digital signatures since 2003 and makes the CodeB product family, including CodeB eForms Server and ZUGFeRD Pro.
Which languages does CodeB Wallet support?
CodeB Wallet is available in English, German and Maltese. It uses your phone’s language automatically – English for all other languages – and you can choose a different language under Settings → Language.
What is an EU Digital Identity Wallet?
eIDAS 2.0 (Regulation (EU) 2024/1183) introduces European Digital Identity Wallets: apps in which people can store identity data and other attestations and share them securely with public and private services. The technical rules are described in the EU Architecture and Reference Framework (ARF).
Which documents can I store?
Person Identification Data (PID) including the German PID, a mobile driving licence in SD-JWT VC and ISO/IEC 18013-5 mdoc format, and the CodeB membership card – all from the CodeB issuer (phone.codeb.io). You add them from the issuer list in the app or by scanning an issuer’s QR code.
Can I sign PDF documents with CodeB Wallet?
Yes. CodeB Wallet signs PDFs with an advanced electronic signature (AdES) in PAdES format, with a trusted timestamp, via the CodeB signing service. You confirm every signature, and the PDF stays on your phone. CodeB Wallet uses Aloaha’s own PDF signing technology; Aloaha has been active in PDF development and digital signatures since 2003. These are not qualified electronic signatures (QES).
Can CodeB Wallet check someone else’s ID?
Yes. CodeB Wallet works as an ISO/IEC 18013-5 reader. With “Verify” you choose what you need – for example only “over 18” – and scan the QR code shown in the other person’s wallet. After they agree, the data arrives over Bluetooth. CodeB Wallet checks the issuer’s signature against your list of trusted issuer certificates (CodeB’s own certificate is built in, and you can import more), that the data is unchanged and belongs to the presenting phone, the validity period and the revocation status. You get a clear verdict – trusted, look closer or do not accept – and the data is deleted as soon as you close the result. Wallet and verifier come in one app – many wallet solutions need a separate app for checking IDs.
Can I use it in person and online?
Yes. In person, you start with a QR code or an NFC tap and the data is sent over Bluetooth Low Energy according to ISO/IEC 18013-5 – no internet connection needed. Both Bluetooth roles are supported for broad reader compatibility. Online, websites and apps request data via OpenID4VP, and you confirm every request with your PIN or biometrics.
What does selective disclosure mean?
Selective disclosure lets you share only the information a service needs. For example, you can confirm that you are over 18 without revealing your date of birth. The SD-JWT VC and ISO mdoc formats support this.
Is my data safe?
Your documents and your history are stored only on your phone. Cryptographic keys are kept in the phone’s secure hardware, the wallet is protected by PIN and optionally biometrics, and nothing is shared without your confirmation. The app has no ads, no tracking and no analytics.
In which countries can I use CodeB Wallet?
CodeB Wallet is built for the EU Digital Identity framework, which applies in all EU member states. Our first focus is Malta, Germany and Austria. Which documents you can use depends on the issuers available to you.
Is CodeB Wallet an official or certified wallet?
No. CodeB Wallet is not an official government wallet and it has not been certified. It is developed by Aloaha Limited and designed to comply with eIDAS 2.0 and the EU Architecture and Reference Framework (ARF). We will only call it certified once a certification has actually been completed.
Which issuers can I use?
In Settings you choose which issuers the wallet uses – currently the EU reference issuers and the CodeB issuer. Issuers are checked against EU trusted lists (ETSI).
When can I download CodeB Wallet?
