Question 1

What RFID hardware do we actually need for a one-day campus hiring drive?

Accepted Answer

Count the places where something has to be logged, and put a reader at each one: an encoding reader at the registration desk, a desk reader on the aptitude hall door, one per group-discussion room and one per interview panel. For badge taps that means HF 13.56 MHz readers, which connect over USB to the PC or tablet already sitting on the desk. Every reader we supply ships with an SDK, demo app and source code, so a single tap can capture attendance and the interviewer's score in the same screen instead of in two systems. Where a panel table has no PC at all, an NFC-capable Android phone can stand in for a fixed reader. Whether a desk keeps logging through a network drop and syncs afterwards is a design decision in your own application, not a property of the reader.

Question 2

Which chip should we specify if interviewers will read badges with their phones?

Accepted Answer

Put "NFC Forum compatible HF 13.56 MHz chip" on the purchase specification rather than just "13.56 MHz", because chips in that band do not all behave the same against a handset. NFC Forum Type 2 chips, the NTAG21x or Mifare Ultralight class, are the safe default for phone reads. Mifare Classic is read by many Android handsets but not dependably by all, since that depends on the phone's NFC chipset rather than on the badge; DESFire can be read over NFC, but authenticated reads need the keys handled inside your own app, so a panel room relying on phones alone can stall on the morning of the drive. Note too that a phone reads one badge at a time and its antenna sits in a different place on every model, so tell interviewers where to tap. For a fixed round desk, a USB reader stays more predictable.

Question 3

What does an RFID candidate badge cost, and what changes the price?

Accepted Answer

Badges are quoted against a written specification rather than sold at a list price, because the cost drivers move independently: card body (PVC or PETG), chip family (a Mifare-class chip sits below DESFire), print (single colour against full colour on both sides), sequential numbering, encoding, and quantity. Wristbands are the one item we publish an anchor price for, from about Rs 15 per unit. Two design choices lower the cost per candidate rather than the cost per badge. First, treat the badge as reusable kit: the chip is rewritable, so a badge handed back at the exit can carry a different candidate at the next campus. Second, keep names, scores and round history in your own software and print only a serial. That removes the personalised print run, and it keeps personal data off a chip that walks out of the venue.

Question 4

Can we badge walk-in candidates who did not pre-register?

Accepted Answer

Yes, and it works better designed in than handled as an exception. The usual approach is a stock of serialised blanks, sequentially numbered and encoded at our Delhi factory, kept at the registration desk. The operator binds the next serial to the candidate in your software while entering their details, which takes seconds and needs no printing. Where a named or photo badge is wanted on the spot, an RFID card or label printer that encodes as it prints does both at the desk. Order a buffer above your expected headcount, because custom runs typically take five to ten days and a shortfall found on the morning of a drive cannot be made good in time. Units are tested in-house before dispatch, but read-test the batch yourself when it lands rather than on the day.

Question 5

Do we need any licence or approval to run RFID badge readers at a campus in India?

Accepted Answer

As of 2026 an HF 13.56 MHz badge system is reported to fall under licence-exempt short-range use, so the end user does not normally file for a frequency licence of their own. Treat that as something to confirm rather than as settled. The obligation generally sits on the equipment rather than on the user, so the question for a purchase or tender file is what approvals the hardware carries: ask your supplier in writing for the WPC approval reference covering the specific reader model, and for its BIS documentation. Identium is BIS certified, and the UHF readers and antennas we supply for India's licence-exempt UHF RFID band are WPC-approved. If you add a UHF headcount reader at the hall entrance, 865-868 MHz is the band it must be configured for under the 2021 WPC short-range-device rules — the same range ETSI uses, so the setting to avoid is the 902-928 MHz North American one. Verify the current position with WPC and BIS before committing.
