Why the approach matters for accessibility
01—SMS requires cell service—and a phone number
Text-a-number systems require cellular coverage, which is inconsistent in many exhibit spaces. They also require visitors to submit their phone number to receive content—a privacy concern and a barrier for visitors who aren't comfortable with that exchange. Capption requires neither.
02—Marketing tools and accessibility tools solve different problems
Engage by Cell's core strength is institutional mobile marketing—broadcasting event reminders, collecting leads, and driving engagement. Capption's core strength is removing barriers for visitors who need help accessing exhibit content. These are different use cases that require different designs.
03—Friction is highest for those who need access most
Texting a short code, scanning a QR, or navigating a web app all require steps that create drop-off—especially for aging visitors, non-native speakers, and those with cognitive or physical challenges. Capption's NFC tap removes every step between the visitor and the content they need.
Bottom line
Engage by Cell is a capable mobile marketing and content delivery platform. Capption is an accessibility-first exhibit tool. If visitor inclusion is the goal—not marketing reach—Capption is the purpose-built answer.
