Develop a prototype Dotnet Maui Android C# application running on a Samsung Galaxy Tab Active3 to connect a acr1255u-j1 RfId Reader with BLE connection. The app should be able to continuously read multiple Mifare Classic cards that are tapped on the RfId reader. The RfId reader should beep when reading a card and the card's uid should be output to the console as a 10 digit decimal number. A third party library can be used as long as there are no royalty fees or charges for the library. No Copyleft license libraries should be used. All source code should be in English and provided with no obfuscation and should be buildable in Visual Studio 2022. The manual for the acr1255u-j1 rfid reader is a pdf at Skills and Experience

We are an Access Control manufacturer and we are looking for developers/freelancers/consultants that can help us build our new DESFire EV2 reader. Our hardware is based on ST MCU and we will connect it to an NXP SAM. We less need assistance in hardware design but more in understanding deeply the protocol and the way to use it, and also in defining the requirements for such a product.

Good afternoon JFreddy, We are working on a transit project and need to program some Mifare Desfire EV2 2K cards, the application also uses a SAM to provide new keys and encrypt some data. Are you familiar with programming these cards and would you like to provide some code to assist us in our development? Budget and cost can be discussed once we clafiy if you can or would like to assist thanks Dave

We require assistance and code (Delhpi or C) to assist us in a project that involves programming (key replacement and application creation) of Mifare Desfire EV2 2K cards. Details on exact requirements, level of involvement and projest cost would be discussed with canditates

...Card + QR code reader, developed with NXP PN7150 IC, a QR Code reader module, ESP32 as the microcontroller, and some other peripherals. The PCB ,antenna tuning, code(micropython)is done in-house. The RFID card reader is used to read , ISO14443A ( MIFARE, Desfire, ) and ISO15693 Cards. Only CSN reading is done for now and no key or key management is implemented whatsoever. We are successfully reading the above cards. Now, we are facing a few problems in the functionality 1- The read distance is very low (only about 15 mm read distance for mifare, desfire and 45 mm for iso15693 cards, this should ideally be around 45 and 60 mm respectively.) 2- The read speed is a little bit less than optimal, the card has to be presented and held for a little less than 1 second, this sh...

Hi softtouchsystem, I noticed your profile and would like to offer you my project. We can discuss any details over chat. I need an android apps for NFC mifare desfire Ev1. We need 2 apps: 1 is writting apps, 1 is client apps. Writting apps: The apps can write database ID and secret key to desfire, then encrypt the database ID with secret key, and upload that encrypted ID to server through our api. Client apps: The apps can read database ID, and encrypt the ID using the secret key inside desfire. That encrypted ID will use to verify in our server through our api. The secret key should not be visible nor hackable. Please let me know the estimation.

Create a Flutter NFC Plug in that only reads the UID of the Tag and works in Android and IOS. It's doesn't have to be as complicated as but it does have to use the following Swift co...{String(format: "%.2hhx", $0)}.joined() print("UID Ross 29", UID) print() () } } The Plugin just has to return the UID of the card and not use any of the NDEF calls in Swift. It should behave like other flutter NFC plug ins but the NFC box has to disappear as soon as the mifare Identifier is found. Note - I am only going to respond to quotes less than $100 and you must have Flutter Plugin Experience and an iphone and Android and NFC cards for testing.

Hi. I'm running a cafe. I plan to have a system that controls prepaid items. Ie: customer buys 10pcs product A, 5pcs B, 20pcs C, but will only redeem them progressively. Each customer will be given a contactless card (nfc or mifare), each time an order is made, the card will be used to "pay/redeem" for items. Customers can check their credits at a checkpoint. The system can either be Android(smart phone), RaspberryPi, ESP32, Arduino based. Working offline. Hardwares that I have: Esp32 , esp8266 Rpi NFC reader, cards .Etc

Android and IOS app for NFC-enabled phones to emulate mifare card. The app runs in the background so the user should only bring their phone closer to the reader. Emulates a tag with read write data, type mifare 1K. All data will be manageable from a server. The user can only install the app and give permissions. From the server you can turn the tag on and off, change the ID, read the data memory, and write to the data memory. The app will have id of the phone on which it is installed, so that the tag data cannot be copied to any other phone.
