Abstract

There is described a data collection device that can incorporate an encoded information reading unit than can operate within a system including an access point that is wireline connected to a server. The encoded information reading unit can include at least one of a bar code reading unit, an RFID tag reading unit and a credit/debit card reading unit. Further incorporated in the data collection device can be dynamic access module. The dynamic access communication module enables the data collection device to participate in a self organized network that supports multi-hop data packet transmissions between data collection devices and which further enables the device to transmit data received from a peer device to the system access point.
