NFC wedging via Bluetooth

Specs: Windows 7, Lenovo R500 / 2 GB
I time road races and want a fast sure way to identify finishers. I have successfully used NFC 'tappy' cards but only by a very tricky to manage USB wire. I have already done this by bar code and keypad but they not as sure as NFC.

I want to "wedge" these NFC card reads via Bluetooth. Is there a device that will send NFC card reads to the cursor location?

I'm definitely no expert, but as I understand it, NFC (near field communication) devices only have a range of a few centimeters. Is that the proper technology to be using?

The range numbers are about right. A little more explanation: runners have gotten used to walking away "un-hassled" by having someone grabbing their bib to pull a tag or having to fill out a card. An NFC tap is much surer than either trying to spike tags, keypunch in bib numbers or acquire and xmit a barcode. I have tried all of these. Problem I have with NFC is the wire. If you could bluetooth it like barcode and keypad, it would be great.

I got an AS 10 Bluetooth 13.56 KHz NFC reader and dedicated dongle for under $400. It has a common BLE range. Solid little unit. The operating instructions are typical non-native speaker written confusing / contradictory. The Arkscan people are great to deal with on problems though. It does indeed wedge into my program. Only problem is that it is transmits a HEX like number that I will have to further convert. This is normally no big deal but it will require referencing the cards (to be worn like badges by runners) to a number not directly related to the bib number: Anybody every see bibs denominated in HEX? OK, outside the Bay Area?
Fast, positive, reliable response. Anyway, the unit is very programmable regarding a lot of things I do not need or care about. It does almost as well as a $20 USB unit but it is worth it to get rid of that wire.
Hopefully, I can program cards to numerals only in HEX.
