1. A dialysis system, comprising:
a plurality of dialysate bags:
a plurality of fluid lines coupled to the plurality of dialysate bags;
a plurality of connectors attached to the plurality of fluid lines;
a reader configured to wirelessly access information from the plurality of connectors;
a disposable cassette having a plurality of ports, wherein each respective port of the plurality of ports is fluidly coupled to a respective connector of the plurality of connectors; and
a controller configured to:
receive the accessed information from the reader, wherein the accessed information indicates a first formulation of a first dialysate bag of the plurality of dialysate bags and a second formulation of a second dialysate bag of the plurality of dialysate bags, wherein the first dialysate bag is fluidly coupled to a first port of the plurality of ports via a first connector of the plurality of connectors, and wherein the second dialysate bag is fluidly coupled to a second port of the plurality of ports via a second connector of the plurality of connectors; and
adjust operation of at least one component of the dialysis system based on the accessed information;
wherein adjusting the operation of the at least one component of the dialysis system comprises:
determining that the first formulation of the first dialysate bag is different than the second formulation of the second dialysate bag based on the accessed information; and
mixing a first volume of the first formulation from the first dialysate bag with a second volume of the second formulation from the second dialysate bag to create a volume of mixed dialysate solution;
wherein the first connector includes a first tag of a plurality of tags, and the second connector includes a second tag of the plurality of tags;
wherein each tag of the plurality of tags comprises a chip, a memory, and an antenna, and wherein the memory of a respective tag of the plurality of tags includes multiple bits which specify a respective index of a plurality of indexes, wherein the respective index indicates a respective constituent-concentration-volume combination of a plurality of constituent-concentration-volume combinations, and wherein the respective constituent-concentration-volume combination indicates that a respective corresponding dialysate bag of the plurality of dialysate bags contains a respective volume of a respective formulation and that the respective formulation includes a respective constituent at a respective concentration.
