Extended licence obtaining

Reading card data

With NFC turned on, just tap smartphone to the card to read data.

If this does not work, make sure the card is located near the NFC antenna zone. Some devices have it at unexpected places such as top edge.

Tapping against the same card for the second time would show message "The data are already read".

Assigning athlete's name

SFR Reader allows setting team/athlete's name to each result it reads.

One can set it manually after each reading operation, or in semiautomatic and even fully automatic way. To speed the process up one can upload list of athletes from a text file (UTF-8 encoded) or Event Centre database, to choose the correct name from the list. If the ahtlete in the list has a card number, then SFR reader would automatically use that name for the card.

You can use Excel or any similar program (Open / Libre Office) to prepare the list and save it as CSV-file.

// Line starting with 2 slashes is a comment.
// The file format is trivial: 
// One line — one team

// These teams should be  
// chosen manually
The Furious
Just walking
Quantum snails

// For the following teams
// SFR Reader would use
// card #32 for Swamp kids, 
// and card #34 for John Doe.
