SencorpWhite Adds RFID to Medical Storage Unit

The company's MicroVert secure device for dispensing high-value supplies, pharmaceuticals or blood now comes equipped with RFID, to automatically identify what is removed and returned, and to manage inventory.

Turri likens the MicroVert system to an intelligent vending machine with high security for storing items of great value. The device is designed to provide easy access for those authorized to utilize items stored within. Without RFID, he says, the system can secure items; track who requests access, as well as which items they ask for, via the touch screen; and grant access to authorized individuals—but not track which specific products are being removed. The addition of RFID readers and antennas to the machine provides greater intelligence, he explains; the RFID-enabled version knows which items are being removed, not just the remover's identity, and can communicate instructions to a user, based on that information—such as warning that individual if he or she takes the wrong item.

The RFID-enabled version of the MicroVert comes with a single RFID interrogator and two antennas (SencorpWhite works with a variety of reader and antenna vendors)—one at the door, to read items as they are removed or placed into the unit, and another to perform inventory counts of the supplies stored within the device.

When an individual seeks a product, such as a medical device, from the MicroVert, that person first swipes the magnetic stripe on a personnel badge, uses the touch screen to enter a PIN or performs both functions, in order to indicate his or her identity. The software loaded on the onboard computer identifies whether that worker is authorized to retrieve items from the machine. If so, the solution displays prompts on the touch screen, in order to identify which product that individual seeks, as well as the quantity required. The software then links the product's ID number with the location of that item on a specific shelf, and rotates the shelves to orient the item to a position just behind the door, which is then unlocked.

As the employee removes the item, an ultrahigh-frequency (UHF) EPC Gen 2 passive RFID tag attached to that item transmits its ID number to the antenna installed at the doorway, and the software is updated to indicate the product's removal. If that individual removes more than one of that specific item, the software also detects this action.

Sounds like a useful software.
