Feature Request: enable giving cards "nicknames"

[fischman]

Today distinguishes the cards it's seen by <SYSTEM>: <ID#>. When managing multiple cards (e.g. parents managing kids' cards, and so on) it can get confusing to remember which ID# belongs to whom. IWBN if e.g. a long-press on a scanned card would allow assigning a "nickname" to the card for future display.
