Thibault  said "We would like to set up POS cross boarder acquiring between MALI and BCB in Burundi." A bit confused of word "boarder".
boarder
 noun (especially BrE)
 a child who lives at school and goes home for the holidays: boarders and day pupils
 a person who pays money to live in a room in sb else's house
Example sentense:
A noo boarder and lodger, sir, and looking fit and taut as a fiddle; slep' like a supercargo, he did, right alongside of John - stem to stem we was, all night.'
一位新乘客，或者说一位新房客，先生，而且看上去又精神又整洁，昨晚就香香甜甜地睡在老约翰的身旁——我们船头靠船头。” ---- 金银岛
