- logo or graphic on media, front or back
Definition of tag usage type
- identifying chip
only its N° is useful, the database is on a server,
- tag that identifies and carries information : like a counter, the last 5 control dates: the chip serves as a data file, and no server is needed for this function; it has a memory zone that can carry data assigned to the attached product (e.g. best-before date) and deliver it to a third party, e.g. a customer, who can read it with an Rfid reader without having to use a shared file, and above all identify in a few seconds, in a batch of assembled products, the number and identity of products that have exceeded their best-before date, for example.
- authenticating chip
it has an identifier, its own information and, in addition, a signature which authenticates that the content has not been modified, that what it identifies is genuine - generally the tag is with a “void” visual security which makes it possible to see that the tag has been moved from its holder.
Chip types / frequencies / standards :
- High (13.56 MHz), low (125KHz) and UHF
- standards: please specify: (UHF Gen 2, Mifare ISO 14443A, NFC, etc…)
- chip format and use: please specify, this is important.
- plastic : any shape
- card : flexible, flexible or rigid
- textile, fabrics,
- animal husbandry
- medical monitoring
- PPE monitoring, washing and cleaning
Environmentally-friendly, washable Rfid tag fixing
- screw, rivet, nail (trees, wood),
- weld-on, glue-on, self-adhesive, sew-on,
- insertable, injectable (plastics)
- medical: swallowable (sheep), hypodermic (subcutaneous), injectable (syringe).
The tag attachment part is a major point of the project: small products may require lengthy research and testing: plan to send us samples and the conditions of use and handling of these products.
- As far as the environment is concerned, it is useful to specify from the outset the storage and usage conditions under which RFID tags will be used and handled, and whether they will be exposed to humidity, aggressive cleaning products or disinfectants.
Qualification of Rfid projects
Samples sent by post can be offered on a case-by-case basis, but project qualification and integration tests (in metal objects, for example), custom tag design and reading tests are carried out on a quotation basis. (see the example of the tag embedded in a cork below) are proofs of concept tailored to your needs and are invoiced (“POC” term)as a means of transmitting knowledge.
Rfid principle: a reminder of the technical basics
Most Rfid projects are based on passive tags: they don’t emit without a reader. It is the reader who supplies them with the energy that “wakes them up”, and they respond to the reader’s questions (their identifier, for example) and exchange data.
- An inlay consists of a chip attached to an antenna.
- A “tag” (also known as a “transponder”) is an inlay protected in a protective medium: plastic, glass or paper.
Basically, each chip has a unique number (identifier) which it sends back to the reader.
Then, as an option, this chip can have memory zones.
The data on the tag, i.e. the chip, can be fixed (definitive) or rewritable (R/W): this means you can store history or tracking data for objects that pass from one person or company to another, without having to exchange files between computer systems. It’s a memory that can be transmitted from person to person, with the ability to be read (or protected by a password or key) like a small USB key, without the need for a USB. If you’re working on a single project, chips with a unique identifier are all you need.
Depending on the chip, zones can be read-protected or encrypted (e.g. Hitag-S), making it possible to carry out authentication projects for valuable products.
Reading distances are therefore proportional to the power of the reader’s antenna: in practice, from a few millimeters (like “NFC”: Near Field Contact) to a few meters like UHF.
There are also active tags.
battery-powered tags, which transmit without the need for a reader. They can be seen from a greater distance: several dozen meters.
Size of user memory zones:
A tag with user memory is a small file that accompanies the product. Its primary use is to transfer information from a supplier to a customer, for example, product by product.
Well, small enough: as the price of the tag is related to the size of the memories, it’s obvious that the memory zones aren’t very big, and you have to compete with ingenuity and integrate the coding into the ERP upstream to accommodate the necessary on-board data: we start at 128 bits, or 16 bytes, so a date (DLUO or DLC) for example (2 bytes) and 14 alphanumeric characters, or 28 numeric characters…and that’s plenty! We can go up to 1Kb, but that’s becoming rare and quantities are limited.
Encoding consists of writing the data into the user’s memory zone.
Don’t confuse RFID technology with GPS transmitters, which can be tracked by satellites (which we don’t do), or with IoT (Internet of Things) terrestrial wide-wave networks: which we also integrate.
The advantage of the Rfid label is that it can be printed (barcode, visually-readable description) and encoded (electronic chip) by a special, yet affordable printer, according to a file.
For example, if you receive goods with best-before dates, item numbers and batch numbers on file: you can print this information on the label, readable by the eye, imagers and Rfid readers simultaneously in a single pass, and the code on the product when it’s unpacked. We supply blank labels that you personalize with your printer according to a program we create for you.
The identification process with non-paper tags is complicated by the fact that visual and electronic personalization takes place in 2 passes. The first pass is carried out by the tag supplier by silk-screen or laser printing on the tag with a unique fixed barcode and human number chosen from a page of numbers with or without an alphanumeric mantissa.
The second pass requires both an imager and Rfid reader with a program for encoding and associating the barcode N° with the chip N° (which is unique) and the product data to be stored on it. Programming is done tag by tag with a reader (which also encodes) with a nearby (programmed) field. This phase requires a customized program that sends the registered and associated data up to the general system (ERP).
As you can see, supplying tags is a complete, complex and far from straightforward project, and therefore a paid service.
