A method for reducing a surface area of a pad limited semiconductor die layout includes choosing an outer die pad row from a group of outer die pad rows on the semiconductor die, each of the outer die pad rows being adjacent an edge of the semiconductor die. A data collection interface is established between a first supply management device and a transaction database, the data collection interface providing the transaction database with access to identification data and event data, the identification data uniquely identifying the product, and the event data relating to a supply chain process step for the product. After the data packet has been switched in the communications device, the original packet loss priority information which was switched with the data packets is re-inserted into the corresponding data packet. If not successful, then the authentication switches over to another authentication method if the network requests it. The platform program performs an operation at different predetermined intervals than the coupling program.
