panton...@gmail.com
Ίσως κάποτε να είναι χρήσιμο για κάποιον/αν στην παρέα μας. Αφορά τη δυνατότητα για τυφλούς να χρησιμοποιήσουν τα χαρτονομίσματα διαφόρων χωρών. Το ευρώ δεν συμπεριλαμβάνεται, από ό,τι είδα. Εύχομαι ολόψυχα σε όλες και όλους ένα πιο όμορφο, πιο χαρούμενο, πιο ευτυχές και γεμάτο υγεία 2024. Τάκης

Tactile marks on currencies
This post is primarily created to help blind people who travel to a different country and would like a quick reference on how to recognize the local currencies. There is of course currency recognition apps which one can use, here I will only concentrate on currencies, which do have tactile features. I will explain how to interpret those features.
It is worth mentioning that this list is by no means complete. I have been researching this information for over ten years now, and instead of creating a complete list, I will have to settle with publishing what I have, and add more information as it becomes available. You will find that in case of some countries, I will not list the tactile features of all the circulating bank notes, simply because I was not able to obtain all the information, thus I’ll just document what I have, as I feel that sometimes incomplete information is better than nothing at all.
Here I will only concentrate on the recognition of currently circulating currency, I will write about previously existing tactile features and the history of tactile currency in another document.
Also, since this post is primarily created for blind people, I will not use any pictures. I feel that if the description is not sufficient on its own, I have not done a good job.
As much as possible, I try to have first-hand experience with the listed bank notes, if I have them, I will describe what I can touch. However, it is impossible to have all the bank notes, especially the high value ones. In this case I will use reliable documentations, preferably from national banks and money printers. It is worth noting that sometimes even these organizations don’t have much information, thus I have to write to them, or to the local associations of blind people, which I will use as a last resort.
I hope you will find this information useful during your travels, if you are aware of any features I haven’t listed or have any corrections, please leave a comment on this post.
Angola
On the Angolan Kwanza, the tactile marks can be found along the longer edge, but near the corner.
- 200 Kwanza: one group of two dots
- 500 Kwanza: two groups of two dots (shaped like a square made of four dots, or the braille letter G).
Most likely this pattern continues on the higher denomination notes, but at the moment I don’t have any evidence of it.
Australia
On the Australian bank notes, there are two identical sets of tactile marks, indicating the value along both long edges.
- 5 Dollar: one dot
- 10 Dollar: two dots
- 20 Dollar: three dots
- 50 Dollar: four dots
- 100 Dollar: five dots
Bahrain
On the Bahraini Dinar, the tactile marks can be found along the shorter edge.
- 1/2 Dinar: one line
- 1 Dinar: two lines
As of this writing (December, 2023), it appears that the other notes do not have tactile marks.
Botswana
At the time of this writing (December, 2023), only one bank note has a tactile mark, Botswana plans to issue more.
- 10 Pula: a group of six dots, like a full braille cell on the shorter edge
Brazil
In case of the Brazilian Real, the orientation of lines is important. Therefore, the references should be understood holding the notes horizontally.
The lines can be best felt on new notes, when they are more used, it is difficult or impossible to feel.
- 2 Real: one diagonal line
- 5 Real: one horizontal line, parallel to the longer edge
- 10 Real: two vertical lines
- 20 Real: two diagonal lines
- 50 Real: two horizontal lines
- 100 Real: three horizontal lines
- 200 Real: 3 diagonal lines
Canada
- 5 Dollar: one group of six dots, like a full braille cell on the longer edge
- 10 Dollar: two groups of six dots, like two full braille cells with a space in between along the longer edge. The space is as wide as a braille cell.
- 20 Dollar: three groups of six dots, with one space in between along the longer edge.
- 50 Dollar: four groups of six dots, with one space in between along the longer edge.
- 100 Dollar: two groups of six dots, with a long space in between, about the width of 7 braille cells, along the longer edge.
China
On the Chinese banknotes, the value is indicated with braille like numbers. The orientation is important, the numbers, without a number sign can be found on the lower right. These are not real braille dots, but small raised circles organized in the shape of braille numbers.
- 1 Yuan: braille number 1
- 5 Yuan: braille number 5
- 10 Yuan: braille number 10
- 20 Yuan: braille number 20
- 50 Yuan: braille number 50
Honduras
The Honduran lempira has braille numbers, therefore, the proper orientation is important. Each number is marked with a braille number sign. The braille dots are not easy to feel.
- 2 Lempira: a braille number 2 on the shorter right edge
Hungary
The three lower denominations have short squiggly lines in the corner, these are probably easier to find along the shorter side. However, the lines maybe hard to find on more used bank notes.
- 500 Forint: 1 line
- 1000 Forint: two lines
- 2000 Forint: 3 lines
According to the Hungarian National Bank, the higher three denominations have extra layers of paint along the edges, but they don’t provide more information.
Maldives
Along the longer side there are large shapes made of dots. The dots are sharp and easy to feel, very similar to regular braille dots.
- 5 Rufiyaa: an L shape, or two perpendicular sides of a square
- 10 Rufiyaa: a triangle
- 20 Rufiyaa: a squared C, or a square with one side open
- 50 Rufiyaa: dots in an X shape
- 100 Rufiyaa: a square
- 500 Rufiyaa: dots forming two vertical lines
- 1000 Rufiyaa: a circle
Trinidad and Tobago
In the corner there are large shapes made of dots. The dots are sharp and easy to feel, very similar to regular braille dots. These marks are very similar to the ones on the Maldivian Rufiyaa, the difference is that here they are placed in the corner, so they can be found easily along both edges. Please note that the tactile marks on both currencies are exactly the same, but they indicate different denominations.
- 1 Dollar: two lines made of dots
- 5 Dollar: an L shape, or two perpendicual sides of a square
- 10 Dollar: a squared C, or a square with one side open
- 20 Dollar: a triangle
- 50 Dollar: a circle
- 100 Dollar: dots in an X shape
