Pocket Morse code decoder and symbol chart in one. The card is reversible, easy to store in a wallet or mobile phone or as a pendant. Printed in plastic, it is waterproof and suitable for the outdoors.

To use the decoder side of the card, simply select the left or right side of the decoder according to the initial Morse code symbol (dot or comma) and move in that direction with each additional symbol. The end of the Morse code determines the resulting letter.

The other side of the card contains all the characters and digits.

The card consists of 3 layers, where the middle layer is the color of the font. Due to the greater transparency of the light filaments, two versions are available - for the light and for the dark background version. For printing, pauses are inserted for color changes. PLA or PLA+ material is suitable for printing.
