How do RFID readers read the RFID chip and where does the input go?

I want to build a workflow in Automator and use the RFID chips in a card that have a "product number" and when the reader readers the number it then inputs it into an application that has been setup. So my questions is. When the reader scans the card and gets the "number" where does that "number" go?

What is a RIFD reader?
A RFID reader is a device that uses radiofrequency to wirelessly communicate with RFID tags. It can read information stored on the tags and transmit the data to a computer system for processing. RFID readers are commonly used in inventory management, access control, and asset tracking applications.
What are disadvantage of rfid?
RFID are expensive comparied to BarcodesRFID readers struggle picking up information when passing through metal or liquid.Reader collision can occur where two signals from different readers overlap and the tag is unable to respond to both.Tag collision can occur when numerous tags in the same area respond at the same time.RFID still has two separate chips (read only and readable/writable), which cannot be read by the same machine.
Are rfid readers writers compatible with all chips?
Yes and no, It is common for companies as Texas Instruments & Phillips to lock their technology. However, most reader/writers are compatible with more than their own company's chip-set. frequency range is however not interchangeable. A 125 kHz reader will never be able to read a 13.54 MHz tag.
Did Barack Obama cancel the chip?
There was nothing to cancel. It's an internet myth. There never was any chip. This rumor was spread by people who were opposed to the health care law and wanted you to be afraid of it. But the new health care law contains no demands that everyone have an RFID chip or any other kind of chip. I invited you to read it for yourself you see.
What does RFID use to communicate with a tag attached to an object in computers?
radio Software, Rfid board & antenna Whatever you place on the board with rfid tag with specail software you can read, write and erase the tags. Mostly bar codes for books or dvds.
Are passive RFID tags read-write or write once only?
Passive RFID tags can be both read/write or write-once. They can also be bought pre-written.
...... device are found most often as POS counter to allow customers to authorise credit card purchases electronically?
The device that is found most often as POS counter to allow customers to authorize credit card purchases electronically is a Card Reader. A card reader is a device that can read the information stored on a credit card, such as the card number, expiration date, and security code. A card reader can be connected to a POS system, such as an iPad or a cash register, to process the payment and generate a receipt. There are different types of card readers, such as magnetic stripe readers, chip card readers, and contactless card readers. Magnetic stripe readers use a magnetic head to read the data encoded on the black stripe of a credit card. Chip card readers use a slot to insert the card and read the data stored on the embedded microchip. Contactless card readers use radio frequency identification (RFID) or near-field communication (NFC) technology to communicate with the card wirelessly. Card readers are widely used in retail stores, restaurants, hotels, and other businesses that accept credit cards as a form of payment.
What are the advantages for RFID?
RFID tags don't need to be positioned in a line of sight with the scanner.RFID tags can be read at a faster rate than barcodes.Can read RFID tags from a distance. Information can be read from a tag at up to 300 ft.RFID tags are read/write devices.RFID contain high levels of security; data can be encrypted, passwordRFID tags carry large data capabilities.Once these are set up; it can be run with minimal human participation.RFID tags are reusable.
The use of a magnetic stripe reader?
The data stored on a credit or debit card is stored not only in the metallic chip - but also on a magnetic strip on the rear of the card. Magnetic card readers read the data from the strip on the card, instead of the embedded chip.
Is read denominator a input?
It can be an input.
Why is RFID tags used instead of bar codes use to tag goods?
Both RFID tags and barcodes are used to tag products, but RFID has many advantages. An RFID tag can be read at a distance. That helps with inventorying stock, and also helps to catch shoplifters. Retailers have a problem with shoplifters putting an expensive item in a cheap item's box; because the RFID tag would be on the product itself it wouldn't matter what box it was in.
What's the longest an RFID chip can be read?
Depends on the antenna, frequency, the reader power, and the design. Passive RFID's have a range from a few mm's to a few meters. In general, low frequency = near field rf = short range, higher frequency = far field rf = longer range. EPC HF near field tags have short ranges of less than 1 meter. EPC UHF tags are typically 1-2 meters reliable read. Far field range is very complex and it is possible to have multipath reflection arrangements where 10 meters may work... sometimes. With illegally high power transmitters, and large antennas, far field tags can be reliably read to tens of meters or more for non-commercial designs. Semi-passive RFID's can be read over hundreds of meters. Active RFID's are limited only by their transmit power and antenna design.
