The cards were given different names. Today, they still are. And today you no longer need to hold them in your fist, but some educational and psychology purists would still prefer it that you do. They say that it is good for memory techniques. It helps you to remember important things, things you may not have been familiar with before, better. Among the names given to all these cards were those called flash cards.
This also meant that you did not need to spend hours trying to do your rote learning. You only needed a few minutes every day, and of course, a little bit of patience here and there, and there you go, over time, you would be able to remember important things, things you might not have been familiar with before. You can use these cards to learn the languages of those new faces living in your town.
You can use braille cards to learn the reading language of the blind. This comes in good use for those very few parents today who are blessed with a young, blind child. They can now teach their children how to read as well. And of course, while the young child must still learn his letters, his mom and dad can still read him bedtime stories, but in his own language. The same goes for those children who are deaf or extremely hard of hearing and now need to learn sign language.
All adults can use these touch cards to memorize important sign language words, sentences and phrases and thus communicate so much better with those few folks in their town who are deaf or extremely hard of hearing. And this also opens the way for those with special needs to access jobs that they could not have before.
