Idouble-checked the Compatibility Page and the iPhone 14 Pro is compatible with the Square Magstripe reader with lightning connector. I suggest starting out with the troubleshooting steps listed here. If this doesn't improve things, please reach out to Support directly by logging into your Square account and heading here for further assistance.

I had the same problem. I contacted Square as described in the steps and did everything they asked. They sent me to apple. I did what apple asked, didn't work, and the advanced tech's phone call was disconnected and no one called me back.

As a sheet twisting in the wind, I decided to give it a try to see if it'd still take a payment with the hardware while it flashed this message. I inserted the reader while not in the app, was able to selected other device and lo and behold no more flashing message. This was too simple to fix and no one knew what to do.

Hello everyone

i am new to powerapp

i am trying to make application with barcode reader to scan barcode on the shelf of medication and view expiry dates stored in my list already and update it

my issue is : I want the barcode reader to show the scanned code in the textbox and conduct searching in gallery and at same time i want the text box to search manually also my medicine name

i tried a lot but nothing success

Hi @mmollet , I have followed you step but failed on the last one, finally nothing come out after scan the barcode. Could you please let me know which step I did wrong? Thanks in advance. I am very new on Power Apps...

This would go in the search box as the default text. What it does is it checks if the scannedvalue is blank. If it is blank then it means that we have no scanned anything to search for so we want to show the entire unfiltered list. If there is an object in that scannedvalue then we want to show that in this textinput so that the gallery filters correctly.

Basically the gallery is filtering based on the value in the text input so we are just controlling that. if the scanner wasnt used then the user can type to search but if the scanner was used then it will search/filter based on that scanned value instead. The user can still backspace that and search by their own values as well.

Now add the variable scannedValue to your text input box or label or wherever you want the scanned value to be seen. If you want it to also search/filter your gallery then you can try the following in the items property:

Clojure is a homoiconic language, which is a fancy term describing the fact that Clojure programs are represented by Clojure data structures. This is a very important difference between Clojure (and Common Lisp) and most other programming languages - Clojure is defined in terms of the evaluation of data structures and not in terms of the syntax of character streams/files. It is quite common, and easy, for Clojure programs to manipulate, transform and produce other Clojure programs.

That said, most Clojure programs begin life as text files, and it is the task of the reader to parse the text and produce the data structure the compiler will see. This is not merely a phase of the compiler. The reader, and the Clojure data representations, have utility on their own in many of the same contexts one might use XML or JSON etc.

One might say the reader has syntax defined in terms of characters, and the Clojure language has syntax defined in terms of symbols, lists, vectors, maps etc. The reader is represented by the function read, which reads the next form (not character) from a stream, and returns the object represented by that form.

Since we have to start somewhere, this reference starts where evaluation starts, with the reader forms. This will inevitably entail talking about data structures whose descriptive details, and interpretation by the compiler, will follow.

'.' has special meaning - it can be used one or more times in the middle of a symbol to designate a fully-qualified class name, e.g. java.util.BitSet, or in namespace names. Symbols beginning or ending with '.' are reserved by Clojure. Symbols containing / or . are said to be 'qualified'.

Integers can be indefinitely long and will be read as Longs when in range and clojure.lang.BigInts otherwise. Integers with an N suffix are always read as BigInts. Octal notation is allowed with a 0 prefix, and hexadecimal notation is allowed with a 0x prefix. When possible, they can be specified in any base with radix from 2 to 36 (see Long.parseLong()); for example 2r101010, 052, 8r52, 0x2a, 36r16, and 42 are all the same Long.

Characters - preceded by a backslash: \c. \newline, \space, \tab, \formfeed, \backspace, and \return yield the corresponding characters. Unicode characters are represented with \uNNNN as in Java. Octals are represented with \oNNN.

Map literals can optionally specify a default namespace context for keys in the map using a #:ns prefix, where ns is the name of a namespace and the prefix precedes the opening brace { of the map. Additionally, #:: can be used to auto-resolve namespaces with the same semantics as auto-resolved keywords.

Keys that are keywords or symbols with a namespace are not affected except for the special namespace _, which is removed during read. This allows for the specification of keywords or symbols without namespaces as keys in a map literal with namespace syntax.

The keyed values in the map are assigned unevaluated to the relevant fields in the defrecord. Any defrecord fields without corresponding entries in the literal map are assigned nil as their value. Any extra keyed values in the map literal are added to the resulting defrecord instance.

The behavior of the reader is driven by a combination of built-in constructs and an extension system called the read table. Entries in the read table provide mappings from certain characters, called macro characters, to specific reading behavior, called reader macros. Unless indicated otherwise, macro characters cannot be used in user symbols.

Metadata is a map associated with some kinds of objects: Symbols, Lists, Vector, Sets, Maps, tagged literals returning an IMeta, and record, type, and constructor calls. The metadata reader macro first reads the metadata and attaches it to the next form read (see with-meta to attach meta to an object):

^:a 1 :b 2 [1 2 3] yields the vector [1 2 3] with a metadata map of :a 1 :b 2.

A shorthand version allows the metadata to be a simple symbol or string, in which case it is treated as a single entry map with a key of :tag and a value of the (resolved) symbol or string, e.g.:

^String x is the same as ^:tag java.lang.String x

Another shorthand version allows the metadata to be a keyword, in which case it is treated as a single entry map with a key of the keyword and a value of true, e.g.:

^:dynamic x is the same as ^:dynamic true x

A regex pattern is read and compiled at read time. The resulting object is of type java.util.regex.Pattern. Regex strings do not follow the same escape character rules as strings. Specifically, backslashes in the pattern are treated as themselves (and do not need to be escaped with an additional backslash). For example, (re-pattern "\\s*\\d+") can be written more concisely as #"\s*\d+".

For Symbols, syntax-quote resolves the symbol in the current context, yielding a fully-qualified symbol (i.e. namespace/name or fully.qualified.Classname). If a symbol is non-namespace-qualified and ends with '#', it is resolved to a generated symbol with the same name to which '_' and a unique id have been appended. e.g. x# will resolve to x_123. All references to that symbol within a syntax-quoted expression resolve to the same generated symbol.

For Lists/Vectors/Sets/Maps, syntax-quote establishes a template of the corresponding data structure. Within the template, unqualified forms behave as if recursively syntax-quoted, but forms can be exempted from such recursive quoting by qualifying them with unquote or unquote-splicing, in which case they will be treated as expressions and be replaced in the template by their value, or sequence of values, respectively.

The key in each pair is a tag that will be recognized by the Clojure reader. The value in the pair is the fully-qualified name of a Var which will be invoked by the reader to parse the form following the tag. For example, given the data_readers.clj file above, the Clojure reader would parse this form:

by invoking the Var #'my.project.foo/bar on the vector [1 2 3]. The data reader function is invoked on the form AFTER it has been read as a normal Clojure data structure by the reader. For your own data reader functions, you should report errors by throwing instances of RuntimeException with messages providing error information.

Reader tags without namespace qualifiers are reserved for Clojure. Default reader tags are defined in default-data-readers but may be overridden in data_readers.clj / data_readers.cljc or by rebinding *data-readers*. If no data reader is found for a tag, the function bound in *default-data-reader-fn* will be invoked with the tag and value to produce a value. If *default-data-reader-fn* is nil (the default), a RuntimeException will be thrown.

Clojure 1.4 introduced the instant and UUID tagged literals. Instants have the format #inst "yyyy-mm-ddThh:mm:ss.fff+hh:mm".NOTE: Some of the elements of this format are optional. See the code for details.The default reader will parse the supplied string into a java.util.Date by default. For example:

Since *data-readers* is a dynamic var that can be bound, you can replace the default reader with a different one. For example, clojure.instant/read-instant-calendar will parse the literal into a java.util.Calendar, while clojure.instant/read-instant-timestamp will parse it into a java.util.Timestamp:

If no data reader is found when reading a tagged literal, the *default-data-reader-fn* is invoked. You can set your own default data reader function and the provided tagged-literal function can be used to build an object that can store an unhandled literal. The object returned by tagged-literal supports keyword lookup of the :tag and :form:
