An RFID system comprises an intermediate device that includes a first and second antenna coils connected together in a close loop format. The coils are formed on a flexible substrate that can be folded around a magnetic flux blocker such that one loop is on side of the blocker and the other loop is on the other side of the blocker. The intermediate device can then improve communication between a reader on one side of the blocker and a tag on the other. The coil on the reader side of the blocker can receive RF signals being generated by the reader and convert them to an electrical signal that can be passed to the coil on the tag side of the blockage. The second coil can then generate an RF signal that can be transmitted to the tag.
