A radio frequency identification (RFID) transponder includes a current control module for controlling a current consumption of a memory based on an amount of available power, and a control logic for controlling a memory operation in response to the control of the current consumption by the current control module. The RFID transponder further includes a power detector that is configured to continuously monitor and detect the amount of available power and output a power-dependent control signal. The power-dependent control signal is used by the RFID transponder to control the current consumption of the memory in dependence on the available power.

A high speed tabletop and industrial printer is disclosed with integrated high speed RFID encoding and verification at the same time. The industrial printer simultaneously prints on and electronically encodes/verifies RFID labels, tags, and/or stickers attached to a continuous web. The industrial printer comprises a lighted sensor array for indexing the printing to the RFID tags; and a cutter powered from the industrial printer for cutting the web that the RFID tags are disposed on. The industrial printer comprises two RFID reader/writers that are individually controlled. Specifically, one of the RFID reader/writers comprises the ability to electronically encode the RFID tags while the web is moving; and the second RFID reader/writer uses an additional RFID module and antenna on the printer for verifying the data encoded to the RFID tags.

Various aspects of the disclosure generally relate to security for a credit card processing reader. Part of security for a reader is protecting sensitive components, for example components that access information from a credit card during a transaction. An alternative security configuration may include integrated circuits replacing portions of electrically active mesh. This may reduce the size and cost of a reader while maintaining its security with respect to published guidelines.

The method comprises: scanning a barcode and obtaining barcode data; determining whether the barcode data matches preset button switching barcode data; in a case that the barcode data matches the button switching barcode data, switching an active button bit for waking up a scanner from a button at the current side to a button at the other side.

Embodiments of the present disclosure generally relate to systems and methods for detecting misplaced items in an establishment. In one implementation, the system may include at least one processor configured to receive from at least one reader in the establishment, identification signals of tags read by the reader; determine current locations of the tags; and record the current locations of the tags. The processor may also be configured to access a designated location in the establishment for each of the tags; and determine, by comparing the current locations with the designated locations, a particular tag with a current location that differs from the designated location of the particular tag. The processor may also be configured to generate a notification signal when the current location of the particular tag does not match the designated location of the particular tag.
