In the Catholic tradition, holy cards or prayer cards are small, devotional pictures mass-produced for the use of the faithful. They typically depict a religious scene or a saint in an image about the size of a playing card. The reverse typically contains a prayer, some of which promise an indulgence for its recitation. The circulation of these cards is an important part of the visual folk culture of Roman Catholics.
Old master prints 
Old master prints, nearly all on religious subjects, served many of the same functions as holy cards, especially the cheaper woodcuts; the earliest dated surviving example is from 1423, probably from southern Germany, and depicts Saint Christopher, with handcolouring, it is found as part of the binding of a manuscript of the Laus Virginis (1417) which belongs to the John Rylands Library, Manchester. Later engraving or etching were more commonly used. Some had elaborate borders of paper lace surrounding the images; these were called dévotes dentelles in France.
The invention of colour lithography made it possible to reproduce coloured images cheaply, leading to a much broader circulation of the cards. An early centre of their manufacture was in the environs of the Church of St Sulpice in Paris; the lithographed images made there were done in delicate pastel colours, and proved extremely influential on later designs. Belgium and Germany also became centres of the manufacture of holy cards, as did Italy in the twentieth century. Catholic printing houses (such as Maison de la Bonne Presse in France and Ars Sacra in Germany) produced large numbers of cards, and often a single design was printed by different companies in different countries.
Special types of cards 
Special holy cards are printed for Roman Catholics to be distributed at funerals; these are "In memoriam cards", with details and often a photograph of the person whom they commemorate as well as prayers printed on the back. Other specialized holy cards record baptisms, confirmations, and other religious anniversaries. Others are not customized, and are circulated to promote the veneration of the saints and images they bear.
At the end of the nineteenth century, some Protestants attempted to answer these Roman Catholic images with similar images of their own. They produced Bible cards or Sunday school cards, with lithographed illustrations depicting Bible stories and parables, more modern scenes of religious life or prayer, or sometimes just a Biblical text illuminated by calligraphy; these were linked to Biblical passages that related to the image. The reverse typically held a sermonette instead of a prayer. Imagery here was always the servant of text, and as such these Protestant cards tended to be replaced by tracts that emphasized message instead of imagery, and were illustrated with cartoon-like images if they were illustrated at all.
Irish law of 2009 
In Ireland cards are sold certifying that a Mass has been said for the benefit of sick or dead people, and are typically given to the family of the sick or dead person. Disputes arose over the validity of cards issued by priests living outside Ireland. Section 99 of the 2009 Charities Act regulates sales of Mass Cards, which can only be sold "pursuant to an arrangement" with a "recognised person", such as a Bishop, without stipulating whether that person had to be resident in Ireland or not. A court challenge to the new law by a business that sold 120,000 cards a year failed in late 2009. A breach of the law can result in a 10-year prison sentence or a €300,000 fine.
