Solutions to common issues
01Where do I find the CAN?
The CAN is the 6-digit number printed on the Romanian electronic identity card. You use it to open the secure link between the card and your phone.
02What is the difference between the data PIN and the signing PIN?
The 4-digit data PIN gives access to the information on the card. The 6-digit signing PIN authorizes signing.
03What does the app check in a signed PDF?
For compatible formats it checks integrity, signed revisions, certificates, trust chains, timestamps and OCSP/CRL revocation information.
04Does it work without internet?
Reading the card, proof of address and signing happen locally. The internet is used for timestamps, revocation checks and iCloud, if you turn it on.
05What is sent to iCloud?
Only eligible library PDFs (for example signed ones) and their metadata, if you enable sync. A signed PDF is synced in full, including the signing certificate. CAN, PINs, identity reports and proof-of-address documents are not synced.
06Can I share documents through AirDrop or Messages?
Yes. PDFs can be saved to Files or shared through the standard share sheet.
07What if my iPhone cannot read the card?
Remove a thick case, place the eID under the top area of your iPhone, and keep both still until reading completes.
