nfc

G'day. At my office the doors are locked with an NFC reader. We carry around a little NFC tag on our key chains which will read out a number and this then will open the door if the number matches a number in the database. I am tired of carrying around the tag, people keep loosing it, forgetting it and it would be nice to open the door using a Phone - which we tend to always have on us. So I used a credit card which is NFC enabled to readout the NFC information, added this number to the database and can now open doors using my credit card. This is pretty cool. If I forget my keys (most likely they will be on the desk but silly me left the desk without them), I may have my wallet with me. Then I tried Wallet.app on my iPhone and select the same credit card. However the door doesn't open. When looking in the door software I noticed that the tags will always transmit the same number. So does my credit card. However Wallet.app will read out 4 readings (or maybe just one very lon

Hi Guys, if we use our NFC Chip (Background Scanning) with our domain xyz.tld/pages (NFC with URL) than we get following Error: CPSErrorDomain error 2. If we use other URL, than it's works fine, for example, following URLS works fine: xyz.tld xyz.tld/ xyz.tld/page xyz.tld/page/xyz xZz.tld/pages But if we add: xyz.tld/pages xyz.tld/pages/xyz than we got the error CPSErrorDomain-Error 2 we also tried (with different tld) xyz.tlx/pages or x.xyz.tlx/pages (Subdomain, www. to) what works fine.... It makes no sense? Or apple blocked our domain? Scanning with Iphone X or other normal NFC Reader are not a problem and works fine, only Background scanning have this issue. This happen only with background scanning on iOS 14.1 (iphone 12 pro ) and ios 14.4 (18D5030e) (iphone 11 pro) with iphone X 14.1 (18A395) native NFC Scanner it works fine.

I would like to know if it is possible to read/write on tag that are not formatted NFCForum (Ndef). I am especially concern with ISO 15693 tag. NFC Core with NFCISO15693Tag seems to be capable of iy but I couldn't find on the store any application that can do it (with new iphone SE 2020 and iOS14.1)

Hi Team, I am unable to generate certificates anymore as i have reached the maximum limit for pass type ID with NFC certificates. Can you please help to increase the limit to 100? My project needs to generate these certificates. Thanks, Sanga Mithra.

I created a demo to test core NFC and failed to write the iso15693 tag. Byte bytes[8]={0x12,0x21,0x04,0x74,0x65,0x73,0x74,0x00};t NSData *data = [[NSData alloc] initWithBytes:bytes length:8]; [iso15693Tag writeSingleBlockWithRequestFlags:RequestFlagSelect blockNumber:0x04 dataBlock:data completionHandler:^(NSError * _Nullable error) { t if (error) {t tt NSLog(@Failed to write tag!); tt} else { tt NSLog(@write succeeded!); tt } t }]; I couldn't execute successfully and got the error message： Error Domain=NFCError Code=100 Tag connection lost UserInfo={NSLocalizedDescription=Tag connection lost} I would like to ask if core NFC supports writing iso15693tag？ I think I need a successful example of how to create a correct blockdata. I hope someone can help me. Thank you very much！

I'm trying to implement an app with NFC. I have to connect to MIfare tag. I'm notified in tagReaderSection function and the field tags contains a tag, but the value of this tag is [0] = (NFCTag) (0x40) Printing description of ((CoreNFC.NFCTag) (0x40)): ▿ NFCTag t- miFare : (lldb) and im not able to connect to it. In the info file I have add the string: com.apple.developer.nfc.readersession.iso7816.select-identifiers D2760000850101 nfcTagReaderSession = NFCTagReaderSession(pollingOption: [.iso14443], delegate: self) tttt tttnfcTagReaderSession?.begin() tfunc tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) { ttt tttt ttttif case let NFCTag.miFare(tag) = tags.first! { ttttttnfcTagReaderSession?.connect(to: tags.first!) ttttttttttt { What am I doing wrong?? thanks for the support PS: the NFC chip is Mifare Ultralight version 2 productType Ntag(04) [Xcode 12.0, IOS 13.0]
