This is the process of applying personal data (name, surname, card number, expiry date, position, etc.) individually for each card. The data is collected from the database received as a file. Normally, flat number personalisation with personal data is performed in a black colour, yet there is the possibility to use a wide range of different colours: silver, gold, white, red, navy blue, green etc. The font, size and the arrangement are flexible and can be adapted according to the customer’s wishes.
