FDA mandates that all currently manufactured blood glucose monitors must have some kind of dataport (ability for the doctor to download data from the device). They do not mandate what kind. Neither the Bayer Contour Next EZ nor the Accucheck Aviva have a data port accessible by the home user. Both require proprietary cords which apparently are only sold with their software or provided to medical folks. You can buy a cord for the Bayer on Ebay, but I haven't seen one for the Aviva. Also, neither of them use bluetooth.
Just be aware that in using the Contour Next EZ, it only holds up to 400 tests and then starts knocking them off.
For the meters, The Bayer has a round open access port on the side of the unit. The Accu-Check apparently is accessed via the same part where you put the strip.
