(1) It shall be permitted to save a blocking attribute only
1. for lost or stolen identity cards on the revocation list pursuant to Section 10 (4) first sentence, or
2. temporarily with the service provider to check whether the identity card is listed on the revocation lists pursuant to Section 10 (4) first sentence; the data shall be erased immediately after checking. To enable repeated checks as to whether the identity card is listed on the revocation lists pursuant to Section 10 (4) first sentence, in derogation from this provision a service provider verifying identity in accordance with the Money Laundering Act, the Electronic Signature Act or the Telecommunications Act shall not erase a saved blocking attribute until one week after it was first saved.
(2) It shall be permitted to save a blocking code only in the identity card register pursuant to Section 23 (3) no. 12.
(3) It shall not be permitted to save all blocking codes or all blocking attributes centrally.
(4) Data transmitted to service providers for technical reasons or for comparison with the revocation list while checking identity electronically may be saved only for the length of transmission. Processing of data pursuant to Section 18 (3) second sentence shall remain unaffected.
