Short notes on Wallet, vCard, and the formats CardCard touches.

• What is an Apple Wallet pass? — A pkpass is a signed bundle Apple Wallet trusts. Here is what travels inside one and how a CardCard issues it.
• vCard QR codes, briefly — A vCard QR is a contact record encoded as a square — scan with the camera, the contact opens, no website round trip.
• What a digital business card actually is — A digital business card is a public web page plus a wallet-installable record. CardCard ships both, signed, in one issue.
