Contact QR Tools

Encode WiFi credentials, vCards, tel/mailto links, SMS, and WhatsApp deep links for signage and badges.

Contact QR codes replace typing, not judgement. WiFi QRs belong on guest networks with rotation dates; never encode the office admin password on a lobby plaque. vCards should stay minimal — name, phone, email, company — so dense modules still scan on older phones. WhatsApp links need country codes; email and SMS payloads should stay short enough for print. Business card QRs work when the human-readable URL sits under the code for accessibility. Test iOS and Android camera apps before event badges go to print. Pair with Social QR tools when the goal is a profile follow rather than a saved contact, and with Payment QR when the counter also needs UPI. CalcoWorks Contact generators exist so hospitality, classrooms, and support desks stop handwriting SSIDs onto sticky notes that peel by Friday.

Return to this qr contact guide whenever the same class of task reappears, and favour linked related categories on CalcoWorks instead of improvising a parallel tool stack from random search results. Bookmark the hub, reuse the popular and featured tools lists below, and keep assumption notes beside any result you share with teammates or clients.
