Okay I've had a play with tap tap see and my label adapter on my perkins brailler, here's what I've found.
Tap tap see can read the card name but it might take a couple of goes, even once you find the correct side of the card, and it seems to sometimes miss off a word. One card I tried it with was simply labelled griffin and I don't know what kind of griffin. Sighted assistance may be required.
I'm using the duel deck heroes versus monsters, I haven't bothered with sleeves since it's only a duel deck but they are easily available in packs of 80 and highly recommended if you're bothered about keeping potentially valuable cards safe, or playing in proper events at a shop where they might be funny about defaced cards. Double sleeving is best for which you'll need to make sure your outer sleeves are big enough to fit the sleeved card in, the recommendation I've heard is some kind of perfect fit sleeve for the inner and KMC hyper matt for the outer. Triple sleeving is possible with certain sleeves but it's probably overkill for our purposes, double sleeving both gives thicker protection and makes sure there isn't an open end where dirt or liquids could enter.
The label tape, 9mm clear from RNIB here in the UK, sticks to the card well and should do likewise to sleeves though you may have to apply pressure to make it stick down properly. Don't be shy about putting the card face down and press on the back to make it fix, the braille seems remarkably tough. The amount of space available on the card is surprisingly large, you shouldn't have trouble fitting the name on in most cases though you may need to use contractions and go over two lines. Using the 9mm tape there seems enough space for two extra lines of tape, my thoughts would be using the third line for mana costs with the official abbreviations and some invention on our part with the fourth as the card type and any creature stats. Sighted players see one coloured symbol for each mana of a given colour, with another symbol and a number in it for colourless mana or a two coloured symbol for mana that can be one of two colours. Here's how I'd work the mana costs.
Official abbreviations
R red
B black
W white
U blue
G green
From here I'd use X as colourless. For hybrid costs I'd have them next to each other for example WR would be one white or red mana, while I'd have all other symbols separated by spaces such as W space R meaning one white and one red. I'd use one X for each colourless but there's no need to separate these.
For card types I'd go as follows where dashes represent a connection between one or more contracted symbols.
cr creature
in or in-st instant
so sorcery
ln or l-and for land
Ar or ar-t artifact
I've suggested two letter versions as alternatives if you don't know symbols such as the one for AR or AND, or if your local variation of braille uses other contractions than the ones I'm familiar with.
You can then go on to add any keywords you feel necessary such as flying, legendary and so on with whatever abbreviation you're happy with and could potentially even fit the creature's power and toughness in whatever way is clear for you. Just to make it clear feel free to change any of these suggestions if they don't fit the way your brain works.
Thoughts?
