there are 20 cards in total (serials and their addresses can be found in the list below), each of which will be funded with 0.001BTC by UniJoin. i would suggest UniJoin to send the 0.001BTC to the cards only after they have reached the user by mail. this way you can avoid that the valuable satoshis are gone (in case they disappear by mail).
a few words about the UniJoin cards - on the front side the following is printed: serial (bottom left), BTC address (bottom center), qr-code of the respective BTC address and the block time of the production (bottom right). additionally the serial is embossed a second time above the UniJoin slogan.
and on the backside you can find the hologram (thanks to polymerbit) which protects the private key in the form of a qr-code printed on the card (which is additionally secured with a piece of paper). in addition, both sides have been professionally laminated and have a top quality
