What is a "QCard"?

Essentially a wrapper around the standardised VCard format, But designed for maximum portability.

Let's break it down in bash:

# A QCard URL
$ SAMPLE="https://qcard.link/?v=QkVHSU46VkNBUkQNCkZOOkludGVyZXN0ZWQgRGV2ZWxvcGVyDQpOOjtJbnRlcmVzdGVkIERldmVsb3Blcjs7Ow0KVElUTEU6R2l0IHNub29wDQpVUkw6aHR0cHM6Ly9xY2FyZC5saW5rDQpOT1RFOllvdSB0cmllZCB0aGUgc2FtcGxlIQ0KVkVSU0lPTjozLjANClVJRDphNDY2YTI0MS1hYzJmLTljZWQtOTdkNy02YTQ4YzQwZGRlMjkNCkVORDpWQ0FSRA=="

# Create a helper to parse the QCard Url,
# This grabs the contents of the `v` parameter and base64 decodes it.
# ---
# 1. echo in the QCard Url.
# 2. grep the `v` parameter and contents.
# 3. cut the first 3 characters.
# 4. base64 decode the result.
$ function qcard() { echo "$@" | grep --only-matching v=.*$ | cut --characters 3- | base64 --decode;}

# Run the helper
$ qcard $SAMPLE

# You can save the contents to a file to import somewhere
$ qcard $SAMPLE > contact.vcf
