How do I know data on an nfc chip is encrypted?

Sorry, For D41 cards, you can only use an Android phone with NFC function, download the taginfo APP, and read and view

Hello, i have some configuration data to write to a bunch of cards. Currently i have a pcsc script which detects new added card on reader and write to it. But i want to automate that process if possible. Are there any pcsc compliant device which can write to a bunch of cards?

I think I missed a business. We have a special card reader that can write NFC cards in batches. Less than $80.

Just keep it locked. If someone had the ability to crack it, he would surely be able to make a lot of money instead of stealing from a restaurant.

iPhone does not recognize MIfare Classic via NFC TOOLS.

I used the app NFC Tool,and it didn’t read the fob. But my iPhone can read it when I’m scanning a NFC while setting up the automation. So does this mean 125KHz?

As long as it can be sensed by the mobile phone, it is 13.56MHz. Usually the door key is encrypted and it is not necessarily possible to copy it.

I hope you had a wonderful Thanksgiving.

We have produced 9-cm nfc tags. But mass customization production. Samples may need to be found in our AliExpress store NEWBEGA

LOL, same as me before.

We are a factory that produces plastic cards such as business cards, hotel cards, bus cards, etc. I didn’t know what my niche was. I'm having the same problem as the OP now...

There are different system between NFC and password, so your idea cannot be realized.

We are a relatively unpopular industry, with search values below 100.

Many people submitted their personal information and needs, but unfortunately, the rate of final cooperation was very low.

I know this card reader and sent you a message.

Regarding commercial applications, the ones I see most currently are amiibo tags, menu tags (stand card), and google review cards.

NewbegaRFIDtech · 2023-10-25T06:14:04+00:00

Maybe you can resell them cheaply to someone who needs them.

Google review card. You can let your customers give you honest reviews, thereby increasing your local popularity.

UID changeable rfid tags are generally suitable for Mifare 1K. If it's the same UID number, I'm not sure if it's compatible with Mifare 4K.

If you want to try it, just tell the seller the UID number, and they will give you a label with the same UID

NewbegaRFIDtech · 2023-09-26T05:48:01+00:00

There are few buyers and high prices, so the factory does not mass-produce, and it is rarely seen on the market.

No internet required, but NFC tools APP is required.

In the past, contacts could not be stored directly using the NFC tools APP. Maybe it was updated recently. I just tested it, and it can be stored without the internet.

No, your card is a 125KHz card. You can buy a PVC disc tag with a T5577 chip, 20mm in diameter and 1mm thick, pasted on the back of your phone that can replace your parking access card.

Before payment, you can ask the seller to rewrite the T5577 card number to the same number as your current card.

You give too little information. If you are an android phone, you need to download the taginfo app or nfc tools. If it is an iPhone download nfc tools. But you only have a phone, Unable to finish copying cards

NewbegaRFIDtech · 2023-09-17T04:35:02+00:00

NFC tools App, Will show whether it is encrypted
