Electronic　Product　Code　(EPC)　and　the　Internet　of　things　are　developing　fast　with　broad　application　prospect,　thus　research　is　done　on　its　data　processing　technologies.　Vending　machine　real-time　data　identified　by　EPC　is　obtained　through　wireless　Internet　of　things.　This　data　is　described　using　Physical　Markup　Language　(PML)　after　data　mergence,　then　data　middleware　is　used　to　do　further　processing.　The　result,　which　is　provided　to　the　remote　vending　machine　support　system,　has　many　commercial　usages.　©　2011　IEEE.
