Business cards, particularly when elevated with QR code, still serve a powerful role in establishing one’s identity and status before a conversation even begins.

Google launches QR code feature for Business Profiles, making it easier to send customers directly to the review page.

Gmail will soon ditch SMS codes for two-factor authentication, and use QR codes instead. This will reduce the impact of global SMS abuse.

You'll soon see a big change in how your Gmail account is secured and your two-factor authenticated logins are handled. Google has said it's planning to stop sending 2FA codes via text message to verify Gmail accounts in favor of security tools such as passkeys and QR codes that you would scan with your device.

You can share the QR code with your customers in your marketing materials or hang it in your store to help them leave you a review.
