Tagalot Cards simulates an 80-column hand card punch, from the early days of computing, and is aimed at educational users and others interested in the history of computing. It can also be used generally for sending retro-style promotional or greetings messages in the form of an 80-column card, with options for adding an image, ‘wash’ text on the card, and even getting into encrypted secret messaging with the use of custom code tables. Social media users can post their message cards as a jpg, gif or mp4 video, with an option for an Instagram-preferred format.
Tagalot Cards is available for iPhone and iPad. The app is free and is the result of a pilot development exploring the use of image metadata to carry messages and contact details, part of the main Tagalot Contacts development. The app is written in Swift 4 and frameworks used include Photos, CoreData, CoreImage, ImageIO, QuartzCore, CoreMedia and MessageUI.
