@funvill: It looks to me with my very limited experience that those would both work and appears to be corroborated by this product at Adafruit using the same reader chip with more clearly-stated specs.
It may be best to wait for someone with more experience to chime in before committing though.
Any reader/writer that follows those standards will work fine, pretty commonly advertised simply as NFC or stating ISO 14443. There are advanced features on the chip that enable password protection, read-only on time switch, etc that go slight beyond the most basica ISO 14443 (ie. ISO 14443-3) but as long as you can read the serial number off of the card that is all that our current systems require. We may expand this in the future.
@toptekkie login to Nomos at http://membership.vanhack.ca and in there you’ll find the Purchase section. I haven’t made an official announcement about purchasing cards because I wanted to test out our issuing system, etc but it’s all working so feel free to go ahead in there! Once payment has been made you’ll need to find a time to be at the space with a director that can issue the card. I’ll make an official post with all the details as soon as I can.
its an NFC card, you can register any NFC tag id to your account to use for space access. The hardware should be installed on the door at VHS in a few weeks, equipment scans, etc to follow.
