Abstract: Authentication method and systems using RFID-enabled payment cards are disclosed herein where a server receives a request corresponding to authorization of a payment associated with a payment card from an electronic terminal. The server identifies an electronic device of a user associated with the payment card. The server then transmits an instruction to the electronic device to cause an RFID reader of the electronic device to determine whether an RFID tag corresponding to the payment card is located within a predetermined proximity to the electronic device. When the payment card is located within the predetermined proximity, the server executes a first authentication protocol. Moreover, when the payment card is not located within the predetermined proximity, the server executes a second authentication protocol, wherein the second authentication protocol is more restrictive than the first authentication protocol.

Abstract: One or more devices are provided that are configured to detachably engage within a modular system. The one or more devices are expandable to provide a surface to perform work.

Abstract: Modular plastic conveyor belts constructed of split belt modules. Each module includes a first piece and a second piece. Side-by-side first pieces mate with side-by-side second pieces to form a row of belt modules. Each row has sets of hinge eyes along opposite ends. Hinge pins extending through the hinge eyes at the ends of each row connect the pieces in the row together to adjacent belt rows. Other components, such as rollers, can be inserted into and removed from the unmated pieces and retained in place by retention structure when the module pieces are mated.

Abstract: Split belt modules used to construct modular plastic conveyor belts. Each module includes a first piece and a second piece, each of which has sets of hinge eyes on opposite ends. The module pieces mate to form complete belt modules. Hinge pins extending through the hinge eyes at the ends of each module connect the pieces together. Other components, such as rollers, can be inserted into and removed from the unmated pieces and retained in place by retention structure when the module pieces are mated.
