Available information shows a RFID (NFC) tag that is used to track the syringe itself. ApiJect has used both terms. The tag is an IoT (Internet of Things) device.
At the time of this writing in December 2021, it does not appear that the ApiJect products are being used. The jabs are being delivered to administrators in multi-dose vials. The ApiJect product is for single dose usage. I do not know if any kind of special syringes are being used for jab administration or who the manufacturer would be.

Whether there is an injectable chip inside the contracted product, as some reports have suggested, is not known to me at this time. Given the reports of Bluetooth connectivity, I cannot rule out the possibility; but I cannot confirm it, either. Please see the PDF brochure for published information about how the NFC tag is intended to be used.
