You can call this new Tangen card as the following printed on the card
Tangem "Digibills beta"
What y think about this idea
BTCI saw the last pic of the card it looks too professional with Tangem logo and name on the right side and also taking 1/4 of the card space/
Make it colorful. I would suggest make the Tangem logo space 1/20 and put some fun stuff on the card like COCO movie style character
Add little holographic look on the card - may be make the Tangem logo holographic around it.
Have fixed Serial number and sequential numbering on the card
It would be nicer if you give a name to the limited edition like
Limited Edition: Digibills
or
Limited Edition: 10 Years Anniversary
Y can use some drawing like this but not exactly
