Mobile file transfer methods and apparatus

An apparatus for transferring blood donation batch files comprising:

• a processor of a user device;
• and
• a memory device storing machine-readable instructions, which when executed by the processor, cause the processor to:
• create a local connection between the user device and a collection device, the local connection including at least one of a private wireless local area network, a direct Bluetooth® connection, or a direct near field communication connection,
• register with the collection device to become a trusted registered user device,
• receive, at a first time, a blood donation batch file from the collection device after the collection device determines the blood donation batch file cannot be transmitted directly to a blood donation information collection server via a network, the blood donation batch file including (i) blood donation information from blood donors, and (ii) metadata related to the blood donation information and the blood donation batch file,
• compare the metadata of the blood donation batch file to metadata of locally stored other blood donation batch files on the memory device,
• after determining that a match does not exist, store the blood donation batch file to the memory device,
• determine communication is not possible with the blood donation information collection server via a wireless connection,
• at a second time after the first time, determine communication is possible with the blood donation information collection server via the wireless connection, and
• transmit the blood donation batch file to the blood donation information collection server after determining communication is possible.
