I'm the student of computer systems engineering. I have to submit my proposal on 10th april. My teachers Have recommend me to design a RFID Based Attendance system for the university with graphical interface in a TABLET PC. (android)

Can anyone elaborate the following concepts for me?

  1. What hardware i will use , and what hardware i will have to design for it?
  2. Why we are using the tablet PC for this purpose? how ever we can do this alone with a rfid reader?
  3. What will be the major benefits of this project by using an android technology here?

my teacher have asked me to google the several questions like that i have found the answers of alot of them..
these questions are yet to be answered!

Kindly help me out as soon as possible ...
i have to give the presentation for this project thank you!

A few focused, practical notes to sharpen the proposal and fill gaps in the thread (building on points from and ).

Start with concrete hardware choices:

  • Tag family: prefer HF/NFC (ISO14443) for short read range and easy tablet integration; avoid long-range UHF unless you need hands-free throughput.
  • Secure tag chips: choose tags that support authentication (DESFire, NTAG with password) rather than relying on a bare UID.
  • Reader options: use the tablet's built-in NFC when possible, otherwise a USB-OTG or Bluetooth reader that speaks a simple protocol.
  • Optional gateway: a small Pi or server for central DB, card issuance printer/encoder if you will create cards.

Simple, robust workflow to describe in the proposal:

  1. Enrollment: issue a secure tag and record student metadata (store only a hashed identifier).
  2. Class check-in: student taps card to the tablet reader; app verifies the tag, records timestamp + device ID, shows success/fail.
  3. De-dup and audit: ignore duplicate taps within a configurable window; cache records offline and sync over HTTPS to the central server.
    Mention Android pieces: NFC API, local SQLite caching, background sync with TLS.

Address proxy and privacy concerns (these are important to defend against s point):

  • Do not rely on UID-only authentication (easy to clone). Use tags with crypto or a challenge-response flow.
  • Use spot checks instead of forcing 2-factor on every student: random biometric/photo checks or a PIN for exceptions reduces queueing.
  • Reduce cross-reads by using NFC/short-range placement and physical gating. Log device ID, timestamp, and a small audit photo or geofence to deter proxies.
  • Protect data: TLS in transit, minimal retention, store hashed IDs, and include a privacy statement/consent in the proposal.

For the presentation, include a short architecture diagram, a hardware list with model examples, a one-week test plan, and a privacy/security section that explains cloning risks and mitigations.

Refuse to develop such an intrusive system that will track students by RFID on security concerns. 
"Psst, hey Jimmy, I want to skip this period, carry my rfid card into class for me please."


1 - At least an rfid reader/scanner and host to run it's software. 
2 - Why a tablet, because it's cool and hip and the latest thing...   Honestly, I have no idea.  Any device that can read a report generated by the host is fine. 
3 - How many tablets are going to review the data??  ?    It's really just attendence data collected by the host and some client will query the report.

i m using only one tablet here for the UI...
but cant we add some security tips in it to stop proxy attendences?

Like what, 2 factor authentication? Rfid and a passcode? CAn you imagine the line of students to get into a lecture hall when 1 forgets his pin and needs a reset?

hey the code will be embedded in the rfid card... they will only swap it on the rfid reader it will sense it and update the data in the database... automatically using the software!
