I have a client who manages multiple dog parks with memberships. There is a person who checks-in the owner & dog (a greeter) and then the owner & dog can leave through another gate at their own discretion. He would like a simple solution where the tag can be scanned with an iPhone or Android device (i.e. NFC or QR code) but can also be read from a distance (e.g. 1.5 meters) when the party is exiting with a reader near the gate.
I was told that the icode slix was a good solution for this but I’m not able to find information and it also seems that in some places it is reported as discontinued. Can anyone point me to a similar solution with current technology that will hopefully stay around for a little while?
Thanks in advance for any help or advice.
