The number ‘1000x’ means that 1000 SATOSHICARDs have been printed and no further issuance is possible. This card has been locked at 1000 cards, but this is not the case for all cards. If the issuer hasn’t locked his card, you’ll see ‘UNLIMITED’ instead of a number.
If you click "TECHNICAL’ you’ll get all history, owner records, etc.
