A system and method for recording, authenticating and verifying transactions of physical items between transacting parties. The system may include memory storing a digital ledger comprising a list of identifiers for a plurality of physical items, each physical item corresponding to a different respective identifier, each identifier being linked in the digital ledger to a public key of an owner of the corresponding physical item, and the list of identifiers and linked public keys being distributed among a plurality of blocks sequentially connected to one another in the digital ledger. The system may also include one or more processors configured to receive a cryptographically signed message including information regarding a transaction of a physical item, including the corresponding identifier of the physical item derived from scanning a label affixed to the physical. The system may verify the message and incorporate the information regarding the transaction into the digital ledger.

Digital ledger for unique item IDs with ownership

A system for maintaining inventory in a retail store may comprise multiple wireless readers. The multiple wireless readers may be distributed throughout the retail store so that every location within a coverage area of the system is within boundaries of at least two wireless readers. Each of the multiple wireless readers may be configured to send polling requests to tags within the coverage area, read responses from the tags, the responses identifying the respective tags, and send identities of the tags to a remote server.

Wireless scanners for maintaining inventory

Methods, systems, and apparatus, including computer programs encoded on computer storage medium, to facilitate real-time inventory tracking using an RFID-enabled light bulb. In one aspect, an apparatus includes a device comprising a light bulb housing having a base with electrical contacts, a lighting element, an RFID reader module, and a network interface configured to provide a connection to a computer network. The apparatus may also include a processor and a data storage device storing instructions that are operable, when executed by a processor, to cause the processor to perform operations. The operations may include causing the RFID reader module to transmit interrogation signals, causing the RFID reader module to detect replies from multiple RFID tags, obtaining the information that uniquely identifies a particular RFID tag from each reply, and transmitting the obtained information over a wireless network connection using the wireless transceiver.
