Local?
In the U.S. the ATMs of at least some banks allow you to set the language to be used for your account. One fellow of my acquaintance set his to Italian, because he was studying Italian and wanted a bit of light "immersion". Apparently his bank stored (for his account or possibly on his card) not the language per se, but the index into a table of languages supported by a given ATM (or group of ATMs?)
At least that is the best we could guess for what happened when he was across town in a Polish neighborhood.
