writing Classic NFC card

Forum / MIFARE and NFC Reader IC`s / writing Classic NFC card

    hi all

    Hoping these are fairly simple questions.

    1) which app is everyone using to write Classic cards? Mifare Classic Tool (MCT) is crashing on Android phone so unusable.

    2) Is there a card type which would allow us to put 2 records on it: 1 record in the same format as the Classic, and 1 record as a URL. We have a couple of Ultralight cards but not sure if these will do the trick.

    Seems from some reading the Ultralight would need to be formatted to allow NDEF format but then not sure whether it would still allow a second URL record to be stored on it as well.

    The reason for the dual record is that we have a couple of sites, half with tablets which the URL record will work on, but the other half have old card readers which read the Classic cards (and can't get these readers replaced unfortunately, stuck with them); so we want a single card that will work at all sites.

    thank you

    Hi Shona,

    Sorry, no clue what “Mifare Classic Tool (MCT)” is?

    You can use all NXP products to write custom data on it! The question is: how much data you want to write and what security do you expect from the tag. Should the communication fully encrypted, should all data on tag secured with a password etc.

    Take in mind that the MIFARE Classic must be supported by your particular NFC reader.

    thank you for your reply

    Mifare Classic Tool (MCT) is an Android app - I am using a Samsung phone to read/write the cards.

    Is it not possible to use an app to write the Classic cards?

    Hi Shona,

    This is not a NXP tool, so, I cannot say anything about it. We have Android tools in Google Play for reading and writing NDEF messages to NXP NFC products (see links below).

    You can write your own Android app and use the TapLinx SDK for writing your own data.

    Please keep in mind, the MIFARE Classic is not supported by all smartphones! This depends on the capabilities of the NFC reader chip. My recommendation is: install the free of charge app “TagInfo” from Google Play and check, if the MIFARE Classic is detected with your phone. If so, you know the internal reader supports the MIFARE Classic.
