QR vCard for Contacts

Warning: This approach uses a free QR API to generate codes dynamically. Since the data is sent to an external service, it is best suited for corporate or publicly available information, avoiding the use of sensitive personal data.

To use this hack, create a new formula field in the Contact object with the return type set to Text, like the one shown in the Formula Explanation section. Add this field to the Contact Page Layout or Lightning page to display the QR code. When users scan this QR code, the contact information will be saved to their mobile devices.

Additionally, since the QR code is generated using an external service, you must add the domain https://api.qrserver.com to CSP Trusted Sites in Salesforce. Otherwise, the image may be blocked and not displayed in Lightning Experience.

Note that this version of the formula does not include substitutions for special characters, meaning that any special characters present in the data fields are not encoded. This can cause issues if the fields contain characters that need to be URL-encoded.
