On December 19, 2005, $100, $200, and $500 MXN banknotes in Series D1 were printed, including raised, tactile patterns, meant to make them distinguishable for people with vision incapacities. This system has been questioned[citation needed] and many demand that it be replaced by actual Braille so it can be used by foreign visitors to Mexico not used to these symbols.[5] The Banco de México said will continue issuing the symbol bills. The tactile patterns would be continued for Series F and a fourth pattern was added to the MXN $1,000 note.[6]
