TokenCards determine how a wallet represents a token visually.
Token Cards instruct a wallet, a dapp browser or a website
how to represent a token. This can include visible instructions,
like icons, colors, a text description or buttons. These visible
properties are set with the
<view> declaration View vs Item-View.
With it token issuers can design how the token appears in the wallet
or on websites. You can think of it similar to a library of CSS
There are also invisible aspects of the token cards. They can define important security parameters like a serial number and other technical properties which are useful for wallets to know.
A token card can have different properties in different circumstances. A soccer ticket token can change its appearance after the game started, and a car leasing token can show different properties depending on your position in the car leasing chain.
