Abstract

It may be determined that a payment reader requires a firmware update, which may be transmitted to the payment reader as compressed firmware update blocks. The payment reader may receive a first portion of set of the compressed firmware update blocks. The payment reader may decompress the first portion and determine a partial firmware offset associated with the first portion. If the firmware update is incomplete, the payment reader may transmit that partial firmware offset to a second device. Based on this partial of firmware offset and an offset table that associates compressed firmware offsets with decompressed firmware offsets, the payment reader receive a second portion of compressed firmware update blocks to send to the payment reader. The payment reader may determine that entire update has been received and update its firmware.
